Answer:
A lens
Explanation:
A lens forms images when light passes Through it bending the rays of in the process.A phenomena called refraction and the speed of light changes in the process because it enters a medium since it's wavelength is reduced.
Positive positive side naturally because protons always move to positive side and electron always move to negative side
Answer:
F=4040.81 N
Explanation:
Given that
Time ,t= 2.45 ms
Mass ,m= 0.055 kg
v= 1.8 x 10² m/s = 180 m/s
We know that rate of change in the linear momentum is known as force.
Momentum P = m v

Therefore force F


F=4040.81 N
Therefore force on the ball will be 4040.81 N
