Answer:

This question is  not complete

Explanation:

There are three ways in which heat is transferred, they are

  • Conduction: Here, heat is transferred from a hot object to a cooler object when both objects come in contact with one another. Here, there must be a contact between the two bodies. This is so because, the particles of the hot objects have a higher kinetic energy than the cooler object, and when they come in contact with the cooler ones, they transfer these energy to the cooler ones. Metals are generally good conductors of heat.
  • Convection: Here, heat is transferred in a liquid or a gas. Hot liquids or gases transfer there heat when they come in contact with cooler ones. There must be contact in this case also. For example, when a kettle of water is boiled, the water at the base of the kettle passes heat energy to the water at the top of the kettle.
  • Radiation: This does not require physical contact but a substance receives heat energy as a result of thermal radiation. For example, the sun produces heat but does not need to touch the metals on earth before they absorb the heat from the sun. So, heat is transferred without a medium or through open space here.

A car ends up colliding with a tree. Compare the force the car exerts on the tree with the force the tree exerts on the car.
Fynjy0 [20]

Answer: The force will exert into the tree causing it to absorb the compact hit by the car which means the car gets damaged severely but the tree maybe only has a tiny crack. Mark me as Brainliest! :)

A muon is traveling at 0.988
AlexFokin [52]

As per Einstein's relation of relativity

m = \frac{m_0}{\sqrt{1 - \frac{v^2}{c^2}}}

here we know that

m_0 = 207 m_e = 207 \times 9.11 \times 10^{-31} kg

m_0 = 1.88 \times 10^{-28} kg

now here we know that

v = 0.988 c

now from above equation mass of the muon is given as

m = \frac{1.88 \times 10^{-28}}{\sqrt{1 - 0.988^2}}

m = 1.22 \times 10^{-27} kg

now for the momentum of muon we can use

P = mv

P = 1.22 \times 10^{-27} \times 0.988(3 \times 10^8)

P = 3.62 \times 10^{-19} kg m/s

so above is the momentum of muon
