Answer:
The speed of the particle is 34.66 m/s.
Explanation:
Given that,
Mass of particle = 50 g
Charge of particle = 4.0 mC
Velocity = 25 m/s
Electric field = 60 N/C
Time = 5.0 sec
We need to calculate the speed in y direction
Using formula of speed

Where, a = acceleration


Put the value in to the formula


We need to calculate the speed of the particle

Put the value into the formula


Hence, The speed of the particle is 34.66 m/s.
Find the intensity of the electromagnetic wave described in each case.
(a) an electromagnetic wave with a wavelength of 645 nm and a peak electric field magnitude of 8.5 V/m.
(b) an electromagnetic wave with an angular frequency of 6.3 ✕ 1018 rad/s and a peak magnetic field magnitude of 10−10 T.
If he stops running the tea is still going to be moving so it will spill on him.
Answer: unequal forces
Explanation: in order for something to accelerate it must speed up or slow down . When unequal forces react it casuse a change in motion which is also know as acceleration .
