Answer:
457.8394 K
Explanation:
= Escape velocity = 2.38 km/s
T = Temperature
R = Gas constant = 8.314 J/mol K
M = Molar mass = 2.016 g/mol
The rms velocity of a molecule is given by
Here,
The temperature of the hydrogen molecule would be 457.8394 K
Answer:
static friction is developed between 2 surfaces in state of rest so i think answer is c.Even though the wheel is in motion, the patch of the tire in contact with the ground is stationary relative to the ground, so it is static rather than kinetic friction.
Answer:
Charge,
Explanation:
A moving particle encounters an external electric field that decreases its kinetic energy from 9650 eV to 8900 eV as the particle moves from position A to position B The electric potential at A is 56.0 V and that at B is 19.0 V. We need to find the charge of the particle.
It can be calculated using conservation of energy as :
q = -20.27 e
Hence, this is the required solution.
Good morning,
the answer you r looking for is (B) electromagnetic radiation.
hope i helped
