Answer 1

Answer:

Steps in the order they should occur:

Observes that there are acidic foodsAsks a question about food’s acidityCreates a hypothesis about the acidityPrepares to conduct the experimentThe student records the acidity of the food.Presents the results to the class

Explanation:


This question is addressed to reflect on the scientific method, and so it deals with the logical steps that are followed regularly in such process.


It is the observation of a natural phenomenum what sparks the whole process. In this case, the student observes that there are acidic foods.


After such observation, some minds, the curious minds, start to ask questions: why?, how?, when?, what happens if? Numerous questions might arise, it is the curiosity attitude, that accompanies the scientific mind. So, the student asks a question about food’s acidity.


The trained scientist then elaborate a hypothesis : a logical tentative prediction which relates a thesis and a conclusion, in the form if _________ then ________, addresed to answer the question. This hypotheisis must be testable, so it must contains objective variables, which can be verified through an experiment by measurements that can be replicated by any one. So, at this point fhe student creates a hypothesis about the acidity.


The next steps are:

Prepares to conduct the experiment: the student must select the independent, dependent and control variables, and plan the materials and equipment needed, the place, the time, the budget, and the special conditions to perform the experiment.The student records the acidity of the food: the experiment is run and the data is recorded, and analyzed, to drive a conclusion:Presents the results to the class: this is how science evolve. The presentation of the results is important because 1) permits the validation of the results by the community, and 2) permits that other scientist use the results to continue with the process, start with a new question, and, might be, to validate a theory or create a new one.

A copper penny has a mass of 3.1 g and a volume of 0.35 cm3. What is the density of copper? Be sure to show your work and include units.

Answers

Density = mass ÷ volume
Density = (3.1g) ÷ (0.35cm^3)
Density = 8.86g/cm^3

The density of copper that has a mass of 3.1 g and a volume of 0.35 cm³ is 8.86g/cm³

HOW TO CALCULATE DENSITY:

The density of a substance can be calculated by dividing the mass of the substance by its volume as follows:

Density (g/cm³) = mass (g) ÷ volume (cm³)

According to this question, copper has a mass of 3.1 g and a volume of 0.35 cm³, hence, the density can be calculated as follows:

Density (g/cm³) = 3.1g ÷ 0.35cm³

Density of copper = 8.86g/cm³

Therefore, the density of copper that has a mass of 3.1 g and a volume of 0.35 cm³ is 8.86g/cm³.

A car accelerates from rest at 3.6 m/s 2 . How much time does it need to attain a speed of 5 m/s?

Answers

car starts from rest

[tex]v_i = 0[/tex]

final speed attained by the car is

[tex]v_f = 5 m/s[/tex]

acceleration of the car will be

[tex]a = 3.6 m/s^2[/tex]

now the time to reach this final speed will be

[tex]t = \frac{v_f - v_i}{a}[/tex]

[tex]t = \frac{5 - 0}{3.6}[/tex]

[tex]t = 1.39 s[/tex]

so it required 1.39 s to reach this final speed

To calculate the time to reach 5 m/s from rest with an acceleration of 3.6 [tex]m/s^2[/tex], the kinematic equation v = u + at is used, where u is zero. Solving for t gives 1.39 seconds.

The question asks about the time it takes for a car to reach a certain speed given a constant acceleration, which falls under the subject of Physics.

To find the time required for the car to attain a speed of 5 m/s from rest with an acceleration of 3.6 [tex]m/s^2[/tex], you use the kinematic equation:

v = u + at

where v is the final velocity, u is the initial velocity, a is the acceleration, and t is the time. Since the car starts from rest, the initial velocity u is 0, and we can rearrange the formula to solve for time:

t = (v - u) / a

Plugging in the given values:

t = (5 m/s - 0 m/s) / 3.6 [tex]m/s^2[/tex] t = 5 / 3.6 t = 1.39 seconds

Thus, the car needs approximately 1.39 seconds to accelerate to 5 m/s.

What parts of clam are likely to be preserved?
A:Hard parts
B:soft parts
C:all parts
D:No parts

Answers

the answer is a. hard parts.

Final answer:

The hard parts of clams are most likely to be preserved as fossils. Soft parts rarely survive the fossilization process due to their rapid decay, and complete fossil preservation including soft parts is extremely rare.

Explanation:

When it comes to preservation, it is the hard parts of bivalves, which include clams, scallops, oysters, and mussels, that are more likely to be fossilized. These organisms have a shell composed of two parts that can open and close, which offers a durable structure capable of surviving long-term geological processes. The soft parts, such as the mouth, heart, intestine, gills, and stomach, typically decay and are rarely preserved; however, there are exceptional occurrences where conditions permit the preservation of soft tissues, as seen with some belemnite fossils, though this is extremely rare.

The alteration of hard parts is a common occurrence in fossil records, resulting in fossil preservation such as permineralization, recrystallization, replacement, carbonization, or dissolution. These processes affect the skeletal material of the hard parts, making them the principal components discovered in fossil records.

If a rock climber accidentally drops a 77.5-g piton from a height of 215 meters, what would its speed be just before striking the ground? ignore the effects of air resistance.

Answers

Let us list out what we know from the question.

Initial Velocity [tex]V_{i}  = 0[/tex] since the piton is 'dropped'.

Vertical Displacement of the piton D = 215 m

Acceleration due to gravity [tex]a = 9.8 m/s^{2}[/tex]

Final Velocity [tex]V_{f} = ?[/tex]

Using the equation, [tex]V^{2} _{f} = V^{2} _{i}  + 2aD[/tex] and plugging in the known values, we get

[tex]V^{2} _{f}  = 0^{2}  + 2(9.8)(215)[/tex]

Simplifying by taking square-root on both sides gives us [tex]V_{f} =  64.915 m/s[/tex]

Thus, the speed of the piton just before striking the ground is 65 m/s.

The speed of the piton just before striking the ground would be approximately 64.94 meters per second.

To determine the speed of the piton just before it strikes the ground, we can use the kinematic equation for an object in free fall under the influence of gravity, ignoring air resistance. The equation is:

[tex]\[ v = \sqrt{2gh} \][/tex]

Given:

- The mass of the piton (m) is [tex]\( 77.5 \, g \)[/tex] or [tex]\( 0.0775 \, kg \)[/tex] (since [tex]\( 1 \, g = 0.001 \, kg \))[/tex],

- The height (h) is 215 m.

We can plug these values into the equation:

[tex]\[ v = \sqrt{2 \times 9.81 \, m/s^2 \times 215 \, m} \] \[ v = \sqrt{2 \times 9.81 \times 215} \] \[ v = \sqrt{4217.7} \] \[ v \approx 64.94 \, m/s \][/tex]

At a distance of 0.75 meters from its center, a Van der Graff generator interacts as if it were a point charge, with that charge concentrated at its center. A test charge at that distance experiences an electric field of 4.5 × 105 newtons/coulomb. What is the magnitude of charge on this Van der Graff generator?

Answers

Since the Van de Graaff generator is given to behave like a point charge, we can use the equation for Electric Field, given as

[tex]E = \frac{kQ}{r^{2} }[/tex]

where, [tex]k = \frac{1}{4\pi ε₀}[/tex] = [tex]8.99 X 10^{9} \frac{Nm^{2} }{C^{2} }[/tex]

r is the distance between the generator and the test charge = 0.75 m

E is the magnitude of the Electric Field Strength = [tex]4.5 X 10^{5} N/C[/tex]

Rearranging the equation, making Q the subject of the formula, we have

[tex]Q = \frac{E.r^{2} }{k}[/tex]

Plugging in the numerical values and simplifying them gets us

[tex]Q = 0.2815 X 10^{-4} \\[/tex]

Thus, the charge on the Van de Graaff generator is 28.16 μC.

When the final velocity is less than the initial velocity, this is , options: speed time acceleration deceleration

Answers

When an object is having variable velocity then we can use the definition of acceleration to find it that rate of change in velocity is known as acceleration.

We can define it as

[tex]a = \frac{v_f - v_i}{\Delta t}[/tex]

here

[tex]v_f[/tex] = final velocity

[tex]v_i[/tex] = initial velocity

[tex]\Delta t[/tex] = time interval

now it is given here that final velocity is less than initial velocity after some time which means

[tex]v_f < v_i[/tex]

so here we can say acceleration will have negative value which shows it is opposite to the direction of velocity.

So this is the case of decreasing velocity which is known as deceleration.

So correct answer is

two objects each weighing 2kg are lifted through the same distance in 4s and 1s respectively. which scenario requires more work?

Answers

i believe it would be the same because time doesn't matter when calculating total work done.

Work=FxD

F=force

D=distance


Final answer:

The scenario that requires more work is when the force applied is greater.

Explanation:

Work is defined as the product of force and displacement.

The work done on an object is given by the formula: work = force × distance × cosine(θ), where θ is the angle between the force and displacement vectors.

In this case, both objects are lifted through the same distance. Therefore, the work done on each object is equal to the force applied to lift the object multiplied by the distance lifted.

The time taken to lift the object does not affect the work done.

So, the scenario that requires more work is when the force applied is greater.

D) As the internal energy increases a substance would go from solid to a liquid.




Answers

D. As the internal energy increases a substance would go from solid to a liquid.

hope this helps :)

Answer: Option (D) is the correct answer.

Explanation:

Internal energy is defined as the minimum amount of energy present within the molecules of a substance.

More is the internal energy within the molecules of a substance more will be the number of collisions between them.

As a results, the particles will move away from each other and this leads to change in state of matter from solid to liquid and liquid to gaseous state.

Thus, we can conclude that the relationship between the internal energy of a substance and its state of matter is that as the internal energy increases a substance would go from solid to a liquid.

A jet airliner moving initially at 548 mph
(with respect to the ground) to the east moves
into a region where the wind is blowing at
343 mph in a direction 67◦
north of east.
What is the new speed of the aircraft with
respect to the ground?
Answer in units of mph.

Answers

Let's choose the "east" direction as positive x-direction. The new velocity of the jet is the vector sum of two velocities: the initial velocity of the jet, which is

[tex]v_1 =548 mph[/tex] along the x-direction

[tex]v_2 = 343 mph[/tex] in a direction [tex]67^{\circ}[/tex] north of east.

To find the resultant, we must resolve both vectors on the x- and y- axis:

[tex]v_{1x}= 548 mph[/tex]

[tex]v_{1y}=0[/tex]

[tex]v_{2x} = (343 mph)( cos 67^{\circ})=134.0 mph[/tex]

[tex]v_{2y} = (343 mph)( sin 67^{\circ})=315.7 mph[/tex]

So, the components of the resultant velocity in the two directions are

[tex]v_{x}=548 mph+134 mph=682 mph[/tex]

[tex]v_{y}=0 mph+315.7 mph=315.7 mph[/tex]

So the new speed of the aircraft is:

[tex]v=\sqrt{v_x^2+v_y^2}=\sqrt{(682 mph)^2+(315.7 mph)^2}=751.5 mph[/tex]

Final answer:

The new speed of the aircraft with respect to the ground, taking into account the wind speed and direction, is approximately 744.91 mph.

Explanation:

To solve this problem, you should first break the wind's velocity into its eastward (x-component) and northward (y-component) using trigonometry. The eastward component is 343 mph x cos(67) = 134.87 mph, and the northward component is 343 mph x  sin(67) = 313.37 mph.

Now, you can add the eastward component of the wind speed to the initial speed of the jet airliner (548 mph + 134.87 mph = 682.87 mph). The northward component of the wind's speed remains the same (313.37 mph) since the plane was initially moving only eastwards with no northwards component.

 

The new speed of the aircraft with respect to the ground (or resultant velocity) can be found using Pythagoras' theorem: √[(682.87)^2 + (313.37)^2] = 744.91 mph.

In electric dryer consumes 6.0×10 6 jewel of energy when operating at 220 V for 30 minutes. During operation the dryer draws a current of approximately?

Answers

Final answer:

The electric dryer, which consumes 6.0×10⁶joules of energy at 220 V for 30 minutes, draws an approximate current of 15.15 amperes during operation.

Explanation:

To determine the current drawn by an electric dryer that consumes 6.0×10⁶ joules of energy while operating at a voltage of 220 V for 30 minutes, we use the relationship between power, voltage, and current given by the equation P = IV, where P is power in watts, I is current in amperes, and V is voltage in volts. First, we need to calculate the power used by the dryer. Power is the rate of energy consumption over time, so:

Power (P) = Energy (E) / Time (t)P = 6.0×10⁶ J / (30 * 60 s) = 6.0×10⁶ J / 1800 s = 3333.33 W

Next, we can calculate the current using the power:

Current (I) = Power (P) / Voltage (V)I = 3333.33 W / 220 V ≈ 15.15 A

Therefore, the electric dryer draws an approximate current of 15.15 amperes during operation.

The current drawn by the electric dryer is approximately [tex]\( {0.00421 \text{ A}} \)[/tex] (or 4.21 mA).

Given:

- Energy consumed [tex]\( E = 6.0 \times 10^6 \)[/tex] joules

- Operating voltage ( V = 220 ) V

- Operating time  t = 30  minutes

First, convert the operating time from minutes to seconds:

[tex]\[ t = 30 \text{ minutes} = 30 \times 60 \text{ seconds} = 1800 \text{ seconds} \][/tex]

Next, convert the energy consumed from joules to kilowatt-hours (kWh):

[tex]\[ E_{\text{in kWh}} = \frac{6.0 \times 10^6 \text{ J}}{3600 \text{ s}} \times \frac{1 \text{ kWh}}{3.6 \times 10^6 \text{ J}} \]\[ E_{\text{in kWh}} = \frac{6.0 \times 10^6}{3600 \times 3.6 \times 10^6} \text{ kWh} \]\[ E_{\text{in kWh}} = \frac{6.0}{12960} \text{ kWh} \]\[ E_{\text{in kWh}} \approx 0.000463 \text{ kWh} \][/tex]

Now, calculate the power P in kilowatts (kW):

[tex]\[ P = \frac{E_{\text{in kWh}}}{t_{\text{in hours}}} = \frac{0.000463 \text{ kWh}}{0.5 \text{ hours}} = 0.000926 \text{ kW} \][/tex]

Convert the power from kilowatts to watts (W):

[tex]\[ P = 0.000926 \text{ kW} \times 1000 = 0.926 \text{ W} \][/tex]

Now, use the formula ( P = VI ) to find the current ( I ):

[tex]\[ I = \frac{P}{V} \][/tex]

Substitute [tex]\( P = 0.926 \text{ W} \)[/tex][tex]\( P = 0.926 \text{ W} \)[/tex] P = 0.926 W and  [tex]\( V = 220 \text{ V} \)[/tex]:

[tex]\[ I = \frac{0.926}{220} \]\[ I \approx 0.00421 \text{ A} \][/tex]

Answers

Final answer:

The person is exerting an equal force of 150 N against the crate, as per Newton's Third Law of Motion, meaning the force exerted by the person is equal to the normal force of 150 N.

Explanation:

To determine how much force a person is currently exerting to lift a crate with a mass of 30 kg, given the normal force supplied by the floor is 150 N, we need to consider the equal and opposite force applied by the person. According to Newton's Third Law of Motion, if the normal force acting upward from the floor is 150 N, then the person must be exerting an equal amount of force in the opposite direction, which would also be 150 N in order to maintain static equilibrium (assuming no other vertical forces are acting on the system, such as acceleration or additional weights).

A 1.00-kg beaker containing 2.50 kg of oil (density = 916 kg/m3) rests on a scale. A 1.90 kg block of iron is suspended from a spring scale and completely submerged in the oil (Fig. P9.30). Find the equilibrium readings of both scales.

Answers

mass of iron block given as

[tex]m_1 = 1.90 kg[/tex]

density of iron block is

[tex]\rho = 7860 kg/m^3[/tex]

now the volume of the iron piece is given as

[tex]V = \frac{m}{\rho}[/tex]

[tex]V = \frac{1.90}{7860} = 2.42* 10^{-4} m^3[/tex]

Now when this iron block is complete submerged in oil inside the beaker the buoyancy force on the iron block will be given as

[tex]F_b = \rho_L V g[/tex]

here we know that

[tex]\rho_L[/tex] = density of liquid = 916 kg/m^3

[tex]F_b = 916* 2.42 * 10^{-4} * 9.8[/tex]

[tex]F_b = 2.17 N[/tex]

Now for the reading of spring balance we can say the spring force and buoyancy force on the block will counter balance the weight of the block at equilibrium

[tex]F_s + F_b = mg[/tex]

[tex]F_s + 2.17 = 1.90* 9.8[/tex]

[tex]F_s = 16.45 N[/tex]

So reading of spring balance will be 16.45 N

Now for other scale which will read the normal force of the surface we can write that normal force on the container will balance weight of liquid + container and buoyancy force on block

[tex]F_n = F_g + F_b[/tex]

[tex]F_n = (1 + 2.50)*9.8 + 2.17[/tex]

[tex]F_n = 34.3 + 2.17 = 36.47 N[/tex]

So the other scale will read 36.47 N

Final answer:

To find the equilibrium readings of the beaker and spring scale, use Archimedes' principle and the concept of buoyancy.

Explanation:

In this question, we are given a beaker containing oil and a block of iron that is submerged in the oil. We need to find the equilibrium readings of both the beaker and the spring scale. To solve this problem, we can use Archimedes' principle and the concept of buoyancy.

The equilibrium reading of the beaker can be found by calculating the weight of the beaker and the weight of the oil it contains. The weight of the beaker can be obtained by multiplying its mass by the acceleration due to gravity, while the weight of the oil can be calculated using its density and volume. The equilibrium reading of the spring scale can be found by calculating the buoyant force acting on the block of iron. The buoyant force is equal to the weight of the fluid displaced by the block of iron, which can be calculated using the density of the oil, the volume of the block, and the acceleration due to gravity.
