Explanation:
Convergent boundaries (where plates collide) and divergent boundaries (where plates split apart).
Answer:
Explanation: The planet average distance = 42300km
Kepler's 3rd Law also known as the Harmonic Law states that;
for each planet orbitting the sun, its side real period squared divided by the cube of the semi-major axis of the orbit is a constant.
A planet, mass m, orbits the sun, mass M, in a circle of radius r and a period t. The net force on the planet is a centripetal force, and is caused the force of gravity between the sun and the planet.
Please find the attached file for the solution
Its either B. force or A. net force but I will go with force because forces can either push or pull I hope it help you.
Answer:
Explanation:
At first, you have to get the acceleration value from the given data.
s= 45m
u= 0 m/s
t = 6s
a = ?
45 = 0+ 0.5 × a × 6²
45 = 0.5 × 36 × a
45 = 18a
a = 2.5 m/s²
Now, you can use F=ma equation
F = ?
m = 1200kg
a = 2.5 m/s²
F = 1200 × 2.5
F = 3000 N
C. hydrogen accreted onto a white dwarf from a close companion rapidly fuses to helium, releasing a large amount of energy.
The accreted material, composed mainly of hydrogen, is compacted on the surface of the white dwarf due to the intense gravitational force on that place. As material accumulates, The white dwarf becomes increasingly hot, until it reaches the critical temperature for ignition of nuclear fusion.
