<span>a. We can find the velocity when the camera hits the ground.
v^2 = (v0)^2 + 2ay = 0 + 2ay
v = sqrt{ 2ay }
v = sqrt{ (2)(3.7 m/s^2)(239 m) }
v = 42 m/s
The camera hits the ground with a velocity of 42 m/s
b. We can find the time it takes for the camera to hit the ground.
y = (1/2) a t^2
t^2 = 2y / a
t = sqrt{ 2y / a }
t = sqrt{ (2)(239 m) / 3.7 m/s^2 }
t = 11.4 seconds
It takes 11.4 seconds for the camera to hit the ground.</span>
Answer:
C. William James

If someone left a movie theater, it is most likely because he likes watching movies there. A better place to interview would be on the streets, as it’s less biased there
Answer:
carrier power is 7.8 kW
Explanation:
given data
power = 10 kW
modulation percentage = 75 %
to find out
carrier power
solution
we will use here power transmitted equation that is
power = 
.................1
put here value in equation 1 we get carrier power
10 = 
carrier power = 7.8
so carrier power is 7.8 kW
