Density is defined as [mass] / [volume] .
The only choice listed with those physical dimensions is 'd' .
Answer:
condensing
Explanation:
Condensing is the word used to indicate the change of state of a substance from vapor to liquid, as in this case. During condensation, the substance releases thermal energy to the environment, therefore the kinetic energy of the molecules in the vapor decreases until they become closer to each other and they start to be affected by the intermolecular forces and so the substance becomes a liquid.
Explanation:
It is given that,
Radius of circular particle accelerator, r = 1 m
The distance covered by the particle is equal to the circumference of the circular path, d = 2πr
d = 2π × 1 m
(a) The speed of satellite is given by total distance divided by total time taken as :
Let t is the period of the particle.
d = distance covered
s = speed of particle
It is given that the charged particle is moving nearly with the speed of light
(b) On the circular path, the centripetal acceleration is given by :
Hence, this is the required solution.
