It should be electromagnetic force
Answer: short displacement has shorter road and long displacement has longer displacement . now think your self Which one is right
Answer:
The change of the volume of the device during this cooling is
Explanation:
Given that,
Mass of oxygen = 10 g
Pressure = 20 kPa
Initial temperature = 110°C
Final temperature = 0°C
We need to calculate the change of the volume of the device during this cooling
Using formula of change volume
Put the value into the formula
Hence, The change of the volume of the device during this cooling is
Answer:
(A) Speed will be
(b) Change in kinetic energy =
Explanation:
We have given mass of proton
Acceleration of the proton
Initial velocity u = m/sec
Distance traveled by proton s = 3.90 cm = 0.039 m
(a) From third equation of motion we know that
(b) Initial kinetic energy
Final kinetic energy
So change in kinetic energy
