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
the answer is spiral galaxies
Answer:
240000 mph² or miles/hour²
Explanation:
<em>Use the formula</em>
<h3>acceleration = change in velocity ÷ time</h3>
change in velocity = 300 mph - 0 mph (final velocity - intial velocity)
time = 0.00125 hours
<em>Substitute the values into the formula:</em>
acceleration = 300 ÷ 0.00125 = 240000 mph²
Answer:
true
Explanation:
the wavelength of AM radio is 10 m whereas FM has 1 m
Answer:
PE = M g H gravitational potential energy
KE - 1/2 M V^2 kinetic energy
PE = KE kinetic energy equal to initial gravitational energy
