Proton is accelerated to a speed of 0.93c, what is the 1. a proton has a mass of 1.673 x 10-27 kg. if the proton is accelerated to a speed magnitude of the relativistic momentum of the proton? a. 6.2 x 10-17 kg. m/s b. 1.3 x 10-18 kg. m/s c. 4.7 x 10-19 kg. m/s d. 5.9 x 10-24 kg. m/s e. 1.8 * 10-18 kg . m/s

Answer : The correct option is, (B)

Explanation : Given,

Mass of proton =

Speed of proton = 0.93 c

Formula used for relativistic momentum of the proton is:

where,

p = relativistic momentum of the proton

= mass of proton

v = speed of proton

c = speed of light =

Now put all the given values in the above formula, we get:

Therefore, the relativistic momentum of the proton is,

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.
