Answer:
see that the correct one is D
Explanation:
In this problem the satellite is subjected to the universal force of attraction
F = G M m / r²
using Newton's second law with centripetal acceleration you can find the angular velocity of the satellite
F = m a
F = m w² r
G M / r³ = w²
and w = 2π / T
In this case, the satellite is in a two-dimensional movement, where the free fall of the satellite is compensated by the horizontal displacement, for which it is always at a distance from the earth, remaining at the same point.
When reviewing the different statements we see that the correct one isD
Many animals rely on their sense to alert them about changes in temperature. <span>Some ways that animals adapt for the seasons include migration, hibernation and physical changes that help them survive the differences in the weather. Hope this helps.</span>

Answer:
<em>7.45 10^5N.</em>
Explanation:
according to newtons second law of motion;
Fapp is the applied force
Fr is the resistive force
m is the mass of the luxury
a is the acceleration
Since the huge luxury liner move with constant velocity, then acceleration is zero i.e a = 0. The equation becomes;
This shows that the applied force will be equal to the resistive force if the velocity is constant.
Given Fr = 7.45 10^5 N therefore the resistive force will also be 7.45 10^5N.
<em>Hence the magnitude of the resistive force exerted by the water on the cruise ship is 7.45 10^5N.</em>
