Answer:
C) Momentum
Explanation:
Refers to an objects mass in motion.
Answer:
Common temporary magnets include nails and paperclips, which can be picked up or moved by a strong magnet. Another type of temporary magnet is an electromagnet which only retains magnetism when an electrical current is running through it.
Explanation:
Answer: 
Explanation:
Given
The voltage of the battery is 
Current through the battery is 
(a) Power is the product of voltage and current
Power dissipates is given by
(b) Energy delivered
Answer:
Varies from point to point on the surface of the material.
Explanation:
Diffusion reflection is the reflection of light due to irregular reflection angles on the material surface. It might be as a result of microscopic irregularities on the material surface or just plain non reflecting ability of the material.
Isothermal process<span> is a </span>change<span> of a </span>system<span>, in which the </span>temperature<span> remains constant: Δ</span>T<span> = 0. So, if the thermodynamic process takes place at a constant temperature so that the internal energy of a system remains unchanged than this process is isothermal.
</span><span>The Joule's second Law states that the internal energy of a fixed amount of an ideal gas depends only on its temperature. So, isothermal processes are of great interest for ideal gasses.</span>
