the movement of heat or electricity through ________. __________ are good conductors, particularly __________. (fill in the blanks)

Answers

materials, metals, gold

Final answer:

The movement of heat or electricity occurs through materials called conductors, with metals like copper and silver being excellent examples due to their high number of free electrons that facilitate this transfer.

Explanation:

The movement of heat or electricity through materials. Metals are good conductors, particularly copper and silver.

Good electrical conductors are often good heat conductors, too. This is because large numbers of free electrons can carry electrical current and can transport thermal energy. Materials like copper, aluminum, gold, and silver are excellent conductors of both electricity and heat due to their high number of free electrons, which allow them to transfer thermal energy efficiently. On the other hand, insulators such as wood, plastic, and rubber are poor heat conductors because they lack these free electrons.

Understanding the conduction of electricity and heat is fundamental in industries and applications that require efficient energy transfer, including electronic components and cooking utensils. Metals are frequently employed in these applications; for example, metals like copper are used in wires for electricity transmission, while cooking utensils are made of metals because of their superior heat conduction abilities.

B.
0.16 meters
C.
0.32 meters
D.
1.8 meters

Answers

Answer:

vertical distance, s = 0.16 meters

Explanation:

It is given that,

An amateur player is about to throw a dart with an initial velocity of 15 meters/second onto a dartboard.

Dashboard is placed at a distance of 2.7 meters.

Calculating time from velocity and distance i.e. [tex]t=\dfrac{d}{s}=\dfrac{2.7}{15}\ s=0.18\ s[/tex]

Using second equation of motion for finding vertical distance :

[tex]s=ut+0.5gt^2[/tex]

Here, u = 0 (for vertical velocity )

[tex]s=0.5gt^2[/tex]  

[tex]s=0.5\times 10\times (0.18)^2[/tex]        

s = 0.162 meters

or s = 0.16 meters

Hence, the vertical distance by which the player will miss the target if he throws the dart horizontally, in line with the dartboard is 0.16 meters.

A hockey player hits a puck so that it comes to rest in 9 s after sliding 30 m on the ice. Determine (a) the acceleration in terms of ,​(4 marks) (b) the initial velocity and acceleration of the puck.​(5 marks)

Answers

Answer:

a) Acceleration, a = -u/9, where u is the initial velocity

b) Acceleration = 0.741 m/s², Initial velocity = 6.67 m/s

Explanation:

 We have equation of motion, v = u + at, where v is the final velocity, u is the initial velocity, a is the acceleration and t is the time taken.

a)  We have v = 0 m/s, t = 9 s

 So,    0 = u + a x 9

      Acceleration, a = -u/9, where u is the initial velocity

b) We have equation of motion , [tex]s= ut+\frac{1}{2} at^2[/tex], s is the displacement, u is the initial velocity, a is the acceleration and t is the time.

 s = 30 m , u = -9a, t =9 s

 So,  [tex]30= -9a*9+\frac{1}{2} *a*9^2\\ \\ 30=-40.5a\\ \\ a=-0.741m/s^2[/tex]

u = -9a = 6.67 m/s

So acceleration = 0.741 m/s², Initial velocity = 6.67 m/s

Final answer:

The answer explains how to calculate the acceleration of the puck given the distance it traveled and the time taken. It further details how to find the initial velocity of the puck using the acceleration obtained earlier.

Explanation:

A. To determine the acceleration of the puck, we can use the equation:

a = 2x / t^2

Substitute the values given: x = 30m and t = 9s.

b. To find the initial velocity of the puck, we first calculate the acceleration using the formula a = Δv / t, where Δv = final velocity - initial velocity.

Then, knowing the acceleration from part (a), we can calculate the initial velocity using the equation v = u + at, where v is the final velocity, u is the initial velocity, a is the acceleration, and t is the time taken.

Select the correct words from the drop-down menus to complete the sentence. The work of a machine can never exceed the work because uses some of the work.

Answers

Answer: The work OUTPUT of a simple machine can never exceed the work INPUT because FRICTION uses some of the work.


Explanation:


This concept is related to ideal machines and efficiency.


Only ideal machines can convert all the work input into useful work (work ouput).


The efficiency is a concept that tells you the proportion of input work that is transformed into output work.


         Efficiency = (output work / input work) × 100


Ideal machines, those where friction does not exist, have a 100% efficiency, and so ideal machines convert all the input work into useful output work.


Real machines have a efficiency less than 100%. Friction lowers the efficiency and the work outpu is less than the work input, because friction uses work which is converted, mostly, into heat energy or sound energy.


You push on a large box with 120 N of force, but it doesn’t move. How large is the friction force?

Answers

the friction force should be 120
Final answer:

The friction force is equal to 120 N. This is based on Newton's First Law. The friction force balances the pushing force, thus keeping the box stationary.

Explanation:

When you push on a large box with 120 N of force and it does not move, it means that the friction force opposing your push is equal to the pushing force. This is based on Newton's First Law of Motion which states that an object in motion tends to stay in motion and an object at rest tends to stay at rest unless acted upon by an unbalanced external force. Friction is the resisting force that occurs between two surfaces in contact when one or both of the surfaces are moved or attempt to move. In this case, the friction force is 120 N because it precisely offsets the applied force, keeping the box stationary.

Use Kepler’s laws and the period of the Moon (27.4 d) to determine the period of an artificial satellite orbiting very near the Earth’s surface.

Answers

Answer:

[tex]T_2 = 1.40 hours[/tex]

Explanation:

As per kepler's law of time period we know that

square of time period is proportional to the cube of the distance

so here we can say

[tex]\frac{T_1^2}{T_2^2} = \frac{r_1^3}{r_2^3}[/tex]

so we know that

for moon

[tex]T_1 = 27.4 days[/tex]

[tex]r_1 = 384,400 km[/tex]

[tex]r_2 = 6370 km[/tex]

now from above formula we have

[tex]\frac{27.4^2}{T_2^2} = \frac{384,400^3}{6370^3}[/tex]

[tex]T_2 = 0.058 days[/tex]

[tex]T_2 = 1.40 hours[/tex]

Using Kepler's third law and the period of the Moon, we find that an artificial satellite very close to Earth has a period of approximately 1.41 hours. This involves comparing the orbital radii and periods using the proportional relationship given by Kepler's law. Substituting values and simplifying yields the final period.

To determine the period of an artificial satellite orbiting very near the Earth’s surface using Kepler’s laws, we will use Kepler's third law, which states that the square of the orbital period (T) is proportional to the cube of the average orbital radius (r). Given the following:

The Moon’s orbital period,  [tex]T_1[/tex] = 27.3 daysThe Moon’s average orbital radius, [tex]r_1[/tex] = 3.84 × 108 mThe radius of the Earth, rE = 6,380 km = 6.38 × 106 mThe altitude of the artificial satellite above the Earth’s surface = 0 m (since it is very near)

Now, add the radius of the Earth to get the orbital radius of the satellite, r2 = rE + 0 = 6.38 × 106 m. According to Kepler’s third law ([tex]T_2[/tex] ∝ [tex]r_3[/tex]), we have:

([tex]T_1[/tex] / [tex]T_2[/tex])2 = ([tex]r_1[/tex] / [tex]r_2[/tex])3

Substitute the known values:

(27.3 / [tex]T_2[/tex])2 = (3.84 × 108 m / 6.38 × 106 m)3

Simplifying the right side:

(27.3 / [tex]T_2[/tex])2 = (60.19)3(27.3 / [tex]T_2[/tex])2 = 217,000

Taking the square root of both sides to solve for [tex]T_2[/tex] :

27.3 / [tex]T_2[/tex] = 465.76[tex]T_2[/tex] = 27.3 / 465.76[tex]T_2[/tex] ≈ 0.0586 days

Converting days to hours (1 day = 24 hours):

[tex]T_2[/tex] ≈ 1.41 hours

Therefore, the period of an artificial satellite orbiting very near the Earth’s surface is approximately 1.41 hours.

Compare how newton understood gravity to how Einstein describes Gravity

Answers

Action= Reaction newton understood gravity
Gravitional wave into the all the universe Einstein describes

Final answer:

Gravity according to Newton is a pulling force between objects with mass, while Einstein's general relativity posits gravity as the warping of spacetime by mass. While Newton's theory works well for less extreme situations, Einstein's accommodates oddities in strong gravitational fields and explains anomalies like Mercury's orbit that Newton's law could not.

Explanation:

Understanding Gravity: From Newton to Einstein

In his universal law of gravitation, Sir Isaac Newton described gravity as a force that pulls any two objects with mass toward one another, proportional to the product of their masses and inversely proportional to the square of the distance between their centers. This concept allowed Newton to explain both the motion of falling objects on Earth and the celestial movements of planets and moons. Objects are drawn towards each other along a line connecting their centers, similar to an invisible 'tug of war.'

Albert Einstein's theory of general relativity, on the other hand, provided a revolutionary understanding of gravity. Instead of viewing gravity as a force, Einstein described it as the warping of spacetime by mass. Massive objects distort the fabric of spacetime, creating what we perceive as gravitational attraction, akin to how a heavy object placed on a stretched-out sheet would cause it to curve and objects around it to roll towards the impression.

Newton's theory operates exceptionally well for everyday phenomena and has been crucial for developments like space travel. However, Einstein's general relativity illuminates peculiar behaviors in strong gravitational fields, such as around black holes, and accounted for the precession of Mercury's orbit, a detail classical physics could not explain. While Einstein's model modifies Newton's, both theories address the observed accelerations of massive bodies influenced by gravity.

It is essential to note that while Einstein's theory adjusts Newton's laws, it does not render them obsolete. Einstein's predictions coincide with Newton's in situations of weaker gravitational fields - a testament to the accuracy of Newton's calculations in familiar conditions. This congruence illustrates Einstein's respect for the robustness of Newtonian physics while extending our understanding to the cosmos's most extreme environments.

So, the right option is (C) which wrong regarding the transmutation.

Final answer:

In the examples given, the transmutation process either involves the emission of particles or the bombardment with neutrons, which leads to a change in the atomic number and transforms the element into a different one. The exception is option C) where Potassium-38's release of a beta particle results in its transformation into Argon-40, not Argon-38 as stated.

Explanation:

Transmutation in chemistry refers to the process wherein an atom of one element is changed into an atom of another element through a nuclear reaction. Of the options provided: A) Uranium-238 emitting an alpha particle to form Thorium-234, B) Uranium-238 being bombarded with a neutron to produce Uranium-239, and D) Plutonium-239 bombarded with two neutrons to produce Americium-241 and a beta particle, are all examples of transmutations. These include the emission of particles or bombardment with neutrons leading to change in the atomic number and forming a different element. However, option C) Potassium-38 releasing a beta particle to form Argon-38 is not an example of a transmutation.

[tex]d_1 = - 37.5 \hat i + 64.9\hat j[/tex]

Other displacement is given as

[tex]d_2 = 155 km[/tex] 60 degree due East of North

[tex]d_2 = 155 sin60 \hat i + 155 cos60 \hat j[/tex]

[tex]d_2 = 134.2 \hat i + 77.5 \hat j[/tex]

now we need to find the net displacement

[tex]d = d_1 + d_2[/tex]

[tex]d = (-37.5 + 134.2)\hat i + (64.9 + 77.5)\hat j[/tex]

[tex]d = 96.7\hat i + 142.4\hat j[/tex]

so it is given as

[tex]d = 172.1 km[/tex]

and its direction is given as

[tex]\theta = tan^{-1}\frac{96.7}{142.4} = 34.1 degree[/tex]

Trade winds near equator blows in curve path instead of straight path. This is because of earth rotation. This effect of earth rotation that cause wind to move in curve motion is called Coriolis effect. These kind of wind blows at the northeast of the North hemisphere and southeast of the South hemisphere. The trade wind are warm and it blows due to rising of hot air from equator.

Final answer:

Trade winds don't blow straight toward the equator because the Coriolis effect causes deflection to the right in the northern hemisphere, forming northeast trade winds, and to the left in the southern hemisphere, forming southeast trade winds.

Explanation:

The trade winds don't blow straight toward the equator due to the influence of the Coriolis effect, which is caused by the rotation of the Earth. In the northern hemisphere, air moving toward the equator is deflected to the right, creating the northeast trade winds. Conversely, in the southern hemisphere, air moving toward the equator is deflected to the left, resulting in the southeast trade winds. These winds converge near the equator in the Intertropical Convergence Zone (ITCZ), leading to very wet conditions and the formation of the world's great rainforests.

Answers

Final answer:

The potential energy gained by driving the car from sea level to Nu’uanu Pali lookout is approximately 3,589,260 joules.

Explanation:

To calculate the potential energy gained by driving your car from sea level up to the Nu’uanu Pali lookout, we can use the formula: PE = mgh, where m is the mass of the car, g is the acceleration due to gravity, and h is the change in height. In this case, the mass is 1000 kg, g is approximately 9.81 m/s², and h is 366 m. Plugging in the values, we get:

PE = 1000 kg * 9.81 m/s² * 366 m = 3,589,260 joules

So, driving your car up to the Nu’uanu Pali lookout increases its potential energy by approximately 3,589,260 joules.

#SPJ2

Final answer:

Objects move or stay still based on Newton's first law of motion or the law of inertia, which states that an object will continue its current state of rest or constant motion unless an external force acts upon it.

Explanation:

What causes objects to move or stay still can be explained by Newton's first law of motion, also known as the law of inertia. This law states that every object will continue to be in a state of rest or move at a constant speed in a straight line unless it is compelled to change by an outside force. For example, if you slide a book on a table, it eventually stops because of the friction (an outside force) between the book and the table.

Similarly, an object moving in an elliptical path, such as a planet, must be subjected to a constant force that keeps changing its direction. Newton proposed this force to be gravity. So, if you throw a ball (a small scale example), it eventually drops to the ground because of the gravitational pull of the earth.

Therefore, without an external force, a stationary object stays put, and a moving object keeps moving at the same speed and in the same direction.

When Amelia apply brakes the car will start reducing its speed and then finally stop

So here as per Newton's First law we can say all object continue its state of motion until and unless some unbalanced external force act upon its.

This property is due to inertia of the object which is the property of mass. Here inertia is the property which resist the change in state of motion of an object.

If brakes are applied and an object stops after some time (let say t = 5 s) and on applying brakes other object stop in other time (let say t = 10 s) then if other object took longer time to stop then it means its inertia will be more.
