Answer:
a) t = 9.16*10^{-18} s
b) y = 0.402 mm
Explanation:
(a) To find the time that the particle takes to pass trough the region between parallel plates, you take into account that the horizontal component of the velocity is constant in all trajectory of the particle. Then, you use the following formula:
x: length of the sides of the plates = 0.22m
v_x: horizontal component of the velocity = 2.4*10^6 m/s
(b) To find the vertical displacement of the particle you first calculate the acceleration of the particle generated by the electric force:
where you have used that the charge is 1.6*10^-19 C (charge of an electron).
With the values of the acceleration and time you use the following kinematic equation to calculate the vertical displacement:
Work = force x distance
Work= 60N x 15m
Work= 900 Newton-meter
Hello! I am not that good at these things but I think that the answer is A
Answer:
Time period,
Explanation:
We have,
The frequency of an FM radio station is 89.3 MHz.
It is required to find the period of the wave.
The reciprocal of frequency is called time period of a wave. It can be given by :
So, the period of the wave is .
When a system looses heat it is considered exothermic and vice-versa endothermic. But something that is considered cold to us can loose heat and become colder. It is therefore necessary to use a specific temperature when referring to the change.
