The closeness of measured values to an accepted value is the BLANK of the data ?

Answers

Answer 1
Answer: accuracy

Justification:

Any measure of a physical data is subject to errors. The errors can be of different kind.

The closer is a measure to the real or accepted value the more accurate the measure is.

For example, if you measure the length of a sheet of paper letter size and you know that the accepted value is 11 inches, then you can tell how accurate your measure is comparing with 11 inches.

Many times the measure is affected by the accuracy of the instrument used (the divisions), but it is also subject to human errors, and may be errors due to the method of measuring.

Describe how a lever can increase the force applied without changing the amount of work being done

Answers

A lever increases applied force by offering a mechanical advantage, which redistributes the force over a longer distance but does not change the overall work done, as work is the product of force and distance which remains constant.

A lever can increase the force applied without changing the amount of work being done by reallocating the distance over which the force is applied. The mechanical advantage provided by a lever allows a smaller input force to lift a heavier load. However, as with all machines, the lever does not change the amount of mechanical work done. This means that a lever that increases force will decrease the distance that the load moves, and the product of the force applied and the distance moved (work) remains constant. The mechanical advantage of the lever is the ratio of these forces, and it demonstrates how a simple machine outputs the same amount of work with a reduced effort force by increasing the distance over which the effort force is applied.

In practice, for instance, when we use a crowbar to lift a heavy object, we apply a small force over a larger distance at one end of the lever (the effort arm), and the crowbar applies a larger force over a shorter distance at the other end (the resistance arm) to lift the object. The work done remains the same since it is the product of force and distance.

According to newton's 2nd law of motion, what is the relationship between mass and acceleration? provide an example to clarify your response.

Answers

In Newton's second law of motion there's a relationship between mass and acceleration. The relationship is that if an object has more mass, then its accelerates faster; however, lighter objects accelerate slower. This law says that outside forces cause the objects to accelerate and the amount of acceleration is relative to the net force and is vice versa proportional to the mass of the object. I hope this helps and I'm sorry if it doesn't!
Final answer:

The relationship between mass and acceleration according to Newton's second law of motion is that acceleration is directly proportional to the net external force and inversely proportional to the mass of the object. So, larger mass leads to smaller acceleration for the same applied force.

Explanation:

According to Newton's second law of motion, the acceleration of a system is directly proportional to and in the same direction as the net external force acting on the system, and inversely proportional to its mass. This essentially means that the larger the mass of an object, the smaller its acceleration will be when a net external force is applied, due to the object's increased inertia. For example, if you try to push a car and a bicycle with the same amount of force, the car (which has a greater mass) will accelerate slower than the bicycle (which has less mass).

a. Hot air balloons use radiation to rise
b. Hot air balloons use conduction to rise
c. hot air balloons use convection to rise
d. hot air balloons use air resistance to rise


Is the answer answer C?,

Answers

C. Hot air balloons use convection to rise.
hot air balloons rise due to convection. Hot air is less dense than cool air; the heated air causes the balloon to rise simply because it is lighter than an equal volume of cold air. the transfer of heat from flame to air is the convection process.

Materials having resistance changes as voltage or current varies are called:

Answers

I believe they are called nonohmic materials. According to ohms law the current trough a current carrying conductor is directly proportional to the potential difference (voltage) at a constant resistance.  Non-ohmic conductors or materials are those materials that do not obey the ohms law, their resistance increases as the current increases. Ohmic materials are those that obeys the ohms law such that the voltage and current are proportional- doubling the potential difference doubles the current.

Example of figurative language the toast jumped out of the toaster. What effect of the argument can go with the example of figurative language

The efficiency of a ramp is 75%. if the amount of work input is 240 j, what is the amount of useful work output?

Answers

the correct answer should be 180 J

Answer:

180

Explanation:

If the work input equals 240 then we follow the equation for work output.

Work output = (work input x efficiency)/100%

Work output = (240 x 75%)/100%

Work output = 180/100%

Work output = 180

Wendy makes a graphic organizer to help herself apply Ohm’s law to electric circuits.



Which formulas belong in the regions marked X and Y?

Y: Req = R1 + R2 + R3
X: Req = R1 + R2 + R3
Y: I =
X: I = I1 = I2 = I3
Y: V = V1 + V2 + V3
X: I =
Y: V = V1 = V2 = V3

Answers

The answer is answer choice B. 
Final answer:

In a series circuit represented by Ohm's law, the correct formulas to use are I = I1 = I2 = I3 for region X and Req = R1 + R2 + R3 for region Y, indicating that current remains constant through components and resistances are additive.

Explanation:

Wendy is working with Ohm's law and electric circuits and needs to know which formulas apply to regions marked X and Y in her graphic organizer. Ohm's law describes the relationship between voltage (V), current (I), and resistance (R) in an electrical circuit and is given by V = IR. When multiple resistors are present in a circuit, their total or equivalent resistance (Req) and the total current depend on whether they are arranged in series or parallel.

In a series circuit, the total current (I) remains the same through all the components, and the voltages across each component add up. Hence, I = I1 = I2 = I3 which would be the correct formula for region X. For region Y, in a series circuit, the equivalent resistance (Req) is simply the sum of all individual resistances, thus Req = R1 + R2 + R3 is the correct formula.

However, in a parallel circuit, the voltage across all components is the same and the currents through each component add up to the total current, which is represented by I = I1 + I2 + I3, but this does not apply to the original question.

A 50 kg astronaut ejects 100 g of gas from his propulsion pistol at a velocity of 50 m/s.what is his resulting velocity

Answers

The total momentum of the system (astronaut+gas) must be conserved.
We can assume the astronaut is still before the gas starts to be ejected, therefore its speed is zero and its momentum is zero as well.
After the gas starts to be ejected, the total momentum of the system is:
[tex]p=m_A v_A + m_G v_G[/tex]
where [tex]m_A=50 kg[/tex] is the mass of the astronaut, [tex]v_A[/tex] is the speed of the astronaut, [tex]m_G=100 g=0.1 kg[/tex] is the mass of the gas and 
[tex]v_G=50 m/s[/tex] is the speed of the gas.
Since the momentum must be conserved, and the initial momentum was zero, then it must be [tex]p=0[/tex]. Using this information, we can find the value of [tex]v_A[/tex], the speed of the astronaut:
[tex]0=m_Av_A + m_G v_G[/tex]
[tex]v_A=- \frac{m_Gv_G}{m_A}=- \frac{(0.1 kg)(50 m/s)}{50 kg}=-0.1 m/s [/tex]
where the negative sign means that the astronaut starts to move in the opposite direction of the ejected gas.

Final answer:

Applying the conservation of momentum, the 50 kg astronaut ejecting 100 g of gas at 50 m/s in space will have a resulting velocity of 0.1 m/s in the opposite direction.

Explanation:

To calculate the resulting velocity of the 50 kg astronaut after ejecting 100 g of gas at a velocity of 50 m/s, we apply the principle of conservation of momentum, assuming a frictionless environment such as space. Before ejection, the astronaut and the gas are stationary, so their combined momentum is 0 kg*m/s. After the ejection, the momentum remains 0 kg*m/s, which means that the momentum gained by the astronaut is equal and opposite to the momentum of the ejected gas.

The mass of the ejected gas is 0.1 kg (100 g) and its velocity is 50 m/s, giving it a momentum of 0.1 kg * 50 m/s = 5 kg*m/s. To find the astronaut's velocity (v_astronaut), we use the equation:

Momentum of astronaut = - (Momentum of gas)

50 kg * v_astronaut = - (0.1 kg * 50 m/s)

This simplifies to:

v_astronaut = - (0.1 kg * 50 m/s) / 50 kg

Calculating this gives:

v_astronaut = - (5 kg*m/s) / 50 kg

So, v_astronaut = -0.1 m/s. The negative sign indicates the direction opposite to the ejected gas.

Therefore, the astronaut's resulting velocity is 0.1 m/s in the direction opposite to the direction of the ejected gas.

If a 375 mL sample of water was cooled from 37.5 C to 0 C how much heat wad lost in joules

Answers

1 mL = 1 gram
Q=375*4.179*37.5
The equation for heat is  
Q = m*Cp*del(T) where 
 Q = heat in Joules
 m = mass in kg
 Cp = the heat capacity of water at a constant pressure = 4,184 J/kgC
 del(T) = the change in temperature in either K or degrees C 
 1 liter of water = 1 kg at standard temperature and pressure. 
 375 mL water x (1 kg/1L water) = 0.375 kg water. 
 Q = (0.375 kg water)(4184 J/kgC)(37.5 C - 0 C) = 58,800 Joules.

What mass of electrons would be required to just neutralize the charge of 5.0 g of protons? (the mass of a proton is 1.67262×10−24g, and the mass of an electron is 9.1×10−28g.)?

Answers

To  neutralize the charge of 1.0g of electrons?

Answer:

[tex]m = 2.72 \times 10^{-3} g[/tex]

Explanation:

total number of protons in 5 gram of total mass is given as

[tex]N = \frac{m}{m_p}[/tex]

here we have

[tex]N = \frac{5}{1.67262 \times 10^{-24}}[/tex]

[tex]N = 2.99 \times 10^{24}[/tex]

now to neutralize the charge we require same amount of negatively charge electrons

so we have

[tex]m = N(m_e)[/tex]

[tex]m = (2.99 \times 10^{24})(9.1 \times 10^{-28})[/tex]

[tex]m = 2.72 \times 10^{-3} g[/tex]

How much work does the electric field do in moving a proton from a point with a potential of +155 v to a point where it is -65 v ? express your answer in joules?

Answers

The work done by the electric field is equal to the loss of electric potential energy of the proton in moving from its initial location to its final location:
[tex]W=-\Delta U = -q \Delta V = -q (V_f -V_i)[/tex]
where [tex]q=1.6 \cdot 10^{-19}C[/tex] is the proton charge, [tex]V_f = -65 V[/tex] and [tex]V_i=+155 V[/tex] are the voltages in the final and initial locations. Substituting, we get
[tex]W=-(1.6 \cdot 10^{-19}C)(-65 V-(+155 V))=3.5 \cdot 10^{-17}J[/tex]

The electric field does -3.52 times 10⁻¹⁷ joules of work in moving a proton from a potential of +155 V to -65 V.

To calculate the work done by the electric field in moving a proton from a point with a potential of +155 V to a point with a potential of -65 V, you need to use the following formula:

Work (W) = q times triangle V, where q is the charge of the proton and triangle V is the change in electric potential (voltage).

The charge of a proton (q) is 1.60 times 10⁻¹⁹ C. The change in electric potential (triangle V) is the final potential minus the initial potential, which is (-65 V) - (+155 V) = -220 V.

So the work done by the electric field is:

W = (1.60 times 10⁻¹⁹ C) times (-220 V) = -3.52 times 10⁻¹⁷ J.

The negative sign indicates that the work is done by the electric field, not by an external force.

F = 11,918 N
V = 713 m/s
t =?

2) Principles and formulas

Impulse and conservation of momentum

I = F.t = Δp

Δp = mΔv

Work is force times distance times the cos of the angle between the two vectors. In this situation there is no distance covered or change in distance, therefore no work can be done. It does take energy from that person to hold the weight, but no work is actually done by holding anything stagnant.

A girl attaches the end of her jump rope to the trunk of a tree. What evidence exists that the rope is a transverse wave?

Answers

Final answer:

The motion of moving the jump rope up and down creates transverse waves where the rope moves perpendicular to the direction of wave propagation. When waves from opposite ends meet, they interfere and superpose, forming various resulting wave patterns.

Explanation:

When a girl attaches the end of her jump rope to the trunk of a tree, evidence that the rope can support a transverse wave is observed by moving the free end of the rope up and down. This motion would cause the rope to move perpendicular to the direction of the wave's travel, which characterizes a transverse wave.

If there were two transverse waves created from opposite ends, with one wave traveling towards the other, one would anticipate seeing a superposition of the two waves when they meet. This interaction, where two waves overlap and combine, is an example of wave interference. The resultant wave pattern can vary depending on the relative phases and amplitudes of the interacting waves, illustrating concepts such as constructive or destructive interference.

Monochromatic light with a wavelength of 384 nm passes through a single slit and falls on a screen 86 cm away. If the distance of the first-order dark band is 0.22 cm from the center of the pattern, what is the width of the slit?

Answers

This is a Fraunhofer single slit experiment, where the light passing through the slit produces an interference pattern on the screen, and where the dark bands (minima of diffraction) are located at a distance of

from the center of the pattern. In the formula, m is the order of the minimum, [tex]\lambda[/tex] the wavelenght, [tex]D[/tex] the distance of the screen from the slit and [tex]a [/tex] the width of the slit.

In our problem, the distance of the first-order band (m=1) is [tex]y=0.22 cm[/tex]. The distance of the screen is D=86 cm while the wavelength is [tex]\lambda = 384 nm=384 \cdot 10^{-7}cm[/tex]. Using these data and re-arranging the formula, we can find a, the width of the slit:
