I believe it is D. Earth spinning on it's axis.
The black squirrel has zero kinetic energy (if it's not moving) and lower gravitational potential energy than the red squirrel or zero gravitational potential energy if the ground is assumed to be zero gravitational potential line.

Answer:
Magnitude of net force will be 432.758 N
Explanation:
We have given x component of acceleration
And vertical component of acceleration
Mass of the ball m = 0.40 kg
So net acceleration
Now according to second law of motion
Force = mass × acceleration
So F = 0.40×1081.896 = 432.758 N
Answer:
C is halved
Explanation:
The frequency and the wavelength of a wave are related by the equation:
where
v is the speed of the wave
f is the frequency
is the wavelength
From the equation above, we see that for a given wave, if the wave is travelling in the same medium (and so, its speed is not changing), then the frequency and the wavelength are inversely proportional to each other.
Therefore, if the frequency doubles, the wavelength will halve in order to keep the speed constant:
