Answer:
I really hope this is right I think this is Diffuse I'm sorry if its worng
Ride in a car down the street: constant velocity,
come to a red light: negative acceleration,
wait for the green light: zero velocity,
<span>start off again: </span>positive acceleration
The answer here would be the force of gravity Hope I could help! :)
Answer:
Explanation:
An object is drop from a height, then it is in direction of gravity
g is +ve
When an object drop from a height, the initial velocity is 0,
U=0
Given that h=4.4×10^7m
V=?
g=9.81m/s^2
Then using equation of motion
V^2=U^2+2gh
V^2=0+2×9.81×4.4×10^7
V^2=86.33×10^7m/s
Take square root of both side
V=29381.63m/s
Now to km/s, divide by 1000
Since 1km=1000m
V=29.38km/s
Answer
The wavelength for 550 kHz signal is
λ = 545.45 m
The wavelength for 1600 kHz signal is
λ = 187.5 m
The wavelength for 88 MHz signal is
λ = 3.41 m
The wavelength for 108 MHz signal is
λ = 2.78 m
