The part of a longitudinal wave where the particles are spread apart is called a______?

Answer:  water vapor

Explanstion

When water is heated it evaporates, which means it turns into water vapor and expands. At 100℃ it boils, thus rapidly evaporating. And at boiling point, the invisible gas of steam is created. ... Those drops of water are called condensation

The steam coming off the pot of boiling water is an example of Water vapor.

Water throughout a gaseous condition, particularly in the atmosphere and at temperatures lower than the boiling point. This same basic ingredient for cloud as well as rain production is water vapor throughout the environment.

It also serves to maintain the Earth's temperature by reflecting and dispersing solar energy as well as absorbing infrared heat from this same Planet.

Thus the response above is correct.

Friction force is a force that opposes relative motion of two bodies that have contacting surfaces

Yes, the velocity of the book will change as it moves across the surface with friction

Reason:

According to Newton's first law of motion, a body will remain at rest or move with a constant speed in a straight line unless acted on by a force

Friction force, f = Normal reaction, N × Coefficient of friction, μ

A surface with friction has frictional force that opposes the relative motion of an object in surface contact across it

When an object such as a book moves across a surface with friction, the friction force acts on the book having a velocity, opposing the motion of the book, therefore, slowing down the book

Therefore, the velocity of the will change (reduce) as it moves across the surface with friction

  The largest diameter is   [tex]d =  0.523 \ m [/tex]

b

The number of revolution is   [tex]n  =  2.132 *10^{4}[/tex]

Explanation:

From the question we are told that

   The kinetic energy of the electron is  [tex]K =  6.5 MeV =  6.5 *10^6 * 1.60 *10^{-19} = 1.04 *10^{-12} \  J[/tex]

    The magnetic field is  [tex]B  =  1.4 \  T[/tex]

       The time is  [tex]t =  1 ms =  1*0^{-3} \  s[/tex]

Generally the kinetic energy of the proton is mathematically represented as

           [tex]KE  =  \frac{1}{2}  *  m * v^2[/tex]

Here m is the mass of the  proton with a value  [tex]m = 1.672 *10^{-27} \  kg[/tex]

    =>  [tex]v  = \sqrt{ \frac{2 *  K }{ m} }[/tex]

=>      [tex]v  = \sqrt{ \frac{2 *  1.04 *10^{-12}  }{ 1.672 *10^{-27}} }[/tex]

=>      [tex]v  = 3.5271 * 10^{7} \  m/s [/tex]

Generally the radius of the largest orbit is mathematically represented as

       [tex]r =  \frac{ m *  v}{ B  *  e}[/tex]

Here e is the charge on a proton with the value [tex]e =  1.60 *10^{-19} \  C[/tex]

         [tex]r =  \frac{ 1.672 *10^{-27} * 3.5271 * 10^{7} }{  1.4  *    1.60 *10^{-19} }[/tex]

=> [tex]r = 0.261 \ m [/tex]

Generally the diameter is

     [tex]d =  2 *  r[/tex]

=>       [tex]d =  2 *  0.261[/tex]

=>       [tex]d =  0.523 \ m [/tex]

Gnerally the period of revolution round the orbit is mathematically represented as

       [tex]T  = \frac{2 \pi  *  m }{B  *  e}[/tex]

=>    [tex]T  = \frac{2 * 3.142  *  1.672 *10^{-27}  }{1.4 *  1.60 *10^{-19}}[/tex]

=>    [tex]T  =  4.691 *10^{-8} \  s [/tex]

Generally the number of revolution is mathematically represented as

      [tex]n  =  \frac{t}{T}[/tex]

     [tex]n  =  \frac{1*10^{-3}}{4.691 *10^{-8} }[/tex]

      [tex]n  =  2.132 *10^{4}[/tex]

This problem occurs with C. only defective spherical mirrors.

Spherical mirrors can be either concave or convex, depending on their shape. A perfect spherical mirror is one that has a consistent curvature across its surface, which allows all the light rays that strike it to properly converge or diverge and focus at the focal point.

However, a defective spherical mirror is one that does not have a perfect curvature across its surface. This can happen due to manufacturing errors or damage to the mirror. When a spherical mirror is defective, the light rays do not properly focus at the focal point, leading to distorted or blurred images.

On the other hand, parabolic mirrors have a unique shape that allows them to reflect incoming light rays to a single focal point, providing a sharper and clearer image compared to spherical mirrors.

Therefore, the correct answer is C. only defective spherical mirrors, as they are the ones that do not properly focus the light rays at the focal point.

Answer:

About 199.864 grams, 4.406 lbs.

Explanation:

By definition, Weight is a measure of the force of gravity pulling down on an object. it is measured in newtons (N), the common unit for measuring force.

Weight is called the action exerted by the force of gravity on the body.

The mass (amount of matter that a body contains) of an object will always be the same, no matter where it is located. Instead, the weight of the object will vary according to the force of gravity acting on it.

The formula that allows you to calculate the weight of any body is:

P = m×g

where:

Then, the weight of an object is the force of gravity on the object, that is, the weight will vary according to the force of gravity that acts on it. So the correct answer is:

Weight is a measure of the force of gravity pulling down on an object. it is measured in newtons (N), the common unit for measuring force.

Answer:

To get your answer multiply 637N by 10N/kg to get 6370kg

The mass of an object weighing 637 N on earth is 65 kg. The acceleration due to gravity on mars is 3.72 m/s². Then its weight on mars is 241.8 N.

The gravitational force is the force by which an object attracts other object into its center of mass. Earth attracts every objects into its surface and that is why we are all standing on the ground and experience a weight.

The acceleration due to gravity is the acceleration to the downward motion by gravitational force for an object.  The weight of an object is the sum of its mass and acceleration due to gravity of the planet in which the object is placed.

The acceleration due to gravity of earth = 9.8 m/s²

then mass of person weighing 637 N = 637 N/9.8 m/s² = 65 Kg

acceleration due to gravity of mars = 3.72  m/s²

then weight of the mass 65 kg = 65 kg × 3.72  m/s² = 241.8 N.

Therefore, the person will weight 241.8 N at mars.

Given that,

A truck drives to a rock quarry at a speed of 20 m/s. The truck takes on a load of rocks, which doubles its mass, and leaves at the same speed of 20 m/s.

To find,

Comparison of the kinetic energy of the truck as it left the quarry with its kinetic energy on the way to the quarry.

Solution,

Kinetic energy of an object is given by:

[tex]K=\dfrac{1}{2}mv^2[/tex]

m is the mass of the truck

[tex]K=\dfrac{1}{2}m\times (20)^2\\\\K=200m\ J[/tex]

If mass is doubled and speed is same i.e. 20 m/s, neew kinetic energy is given by :

[tex]K=\dfrac{1}{2}\times (2m)\times 20^2\\\\K=400m\ J[/tex]

It can be seen that when mass of truck is doubled, its kinetic energy gets doubled.

Answer: D

Explanation: Took the test

Answer:

1,110,114.6 J

Explanation:

The height is 1857m, the mass is 61 kg, and the accelaration is 9.8 m/s^2. Plug in the equation GPE=h*m*a and you get 1,110,114.6.

h= height

m= mass

a= accelaration

GPE= gravitational potential energy

If you are at the grand canyon standing at the edge of a ledge 1857 meters high you have a mass of 61 kilograms, then your gravitational potential energy at the edge of the cliff would be 1111247.37 Joules.

Mechanical energy is the combination of all the energy in motion represented by total kinetic energy and the total potential energy stored energy in the system which is represented by total potential energy.

As total mechanical energy is the sum of all the kinetic as well as potential energy stored in the system.

ME = KE + PE

The total gravitational potential energy at the edge of the cliff would be

PE = m × g × h

PE =61 × 9.81 × 1857

PE =1111247.37 Joules

Thus, the total gravitational potential energy at the edge of the cliff would be  1111247.37 Joules.

Answer:

This is because a thermometer is only meant for measuring temperature and temperature is not a measure of thermal energy

Explanation:

The reason is because a thermometer is designed and calibrated to measure the temperature of a body.

Although the thermal energy of a body is somehow related to its temperature, the thermal energy of a body is not entirely dependent on the temperature of the body

The thermal energy of a body deals with its heat. While thermal energy basically deals with the amount of heat, temperature deals with the flow from one point to another along the body

So what this means is that since thermometer measures this flow, it cannot be used to ascertain the level of heat ( thermal energy) in the body
