Greater the collision
Explanation:
The greater the speed of gas particles in the containers, the greater the collision of gases with the container and between themselves.
- The speed of gas molecules increases when their kinetic energy increases.
- This causes a surge in collision between the particles and the wall of the container.
- A gas is composed of large number of molecules moving at different speeds.
- When the temperature of gases are increased, they gain more kinetic energy and their speed will increase.
- This leads to an increase in effective collision between gas particles.

Answer:
Average force = 67 mn
Explanation:
Given:
Initial velocity u = 0 m/s
Final velocity v = 67 m/s
Time t = 1 ms = 0.001 sec.
Computation:
Using Momentum theory
Change in momentum = F × Δt
(v-u)/t = F × Δt
F × 0.001 = (67 - 0)/0.001
F= 67,000,000
Average force = 67 mn
Answer:
B=9.1397*10^-4 Tesla
Explanation:
To find the velocity first we put kinetic energy og electron is equal to potential energy of electron
K.E=P.E
where :
m is the mass of electron
v is the velocity
V is the potential difference
eq 1
Radius of electron moving in magnetic field is given by:
eq 2
where:
m is the mass of electron
v is the velocity
q=e=charge of electron
B is the magnitude of magnetic field
Put v from eq 1 into eq 2
B=9.1397*10^-4 Tesla
