B they start moving around and stop staying in an orderly manner
The acceleration due to gravity on a large body is given by:
acceleration = (gravitational constant * mass of body) / radius²
For b, this is:
g = GM/r²
M = gr²/G
For a,
g(a) = 1/6 g
r(a) = 1/4 r
M(a) = g(a)r(a)²/G
M(a) = 1/6 g * (1/4 r)²/G
M(a) = gr²/96G
The fraction is given as:
M(a) / M = (gr²/96G) / (gr²/G)
M(a) / M = 1/96
The mass of planet a is 1/96 of the mass of planet b.
Answer:
The bird's average velocity is 4.00 m/s.
Explanation:
Given that,
Distance = 5190 km
Time
We need to calculate the bird's average velocity for the return flight
Using formula of average velocity
Where, d = position
t = total time
Put the value into the formula
Negative sign shows the bird is traveling in negative x -axis.
Hence, The bird's average velocity is 4.00 m/s.
Milankovitch cycles are based on the variations in the orbit of the Earth around the sun and the precession of the axis of the Earth. These cycles are used to explain the cold and warm climates cycles that characterizes during the ice age.The cycles in this are results of the changes in the orbit of the Earth around the sun which includes it eccentricity, shape, the tilt of the axis and its obliquity.
Answer:
1.70 J
Explanation:
The heat dissipated is the difference in the kinetic energies.
This is given by
and are the initial and final velocities.
With <em>m</em> = 0.175 kg,
The negative sign appears because energy is lost.
