D. gravitational force. is your answer hope this helps
Answer:
Because of immense gravity
Explanation:
The formation of the Solar system was a very dynamic process. A lot of matter was thrown towards the outer solar system which further formed the Gas giants: Jupiter, Saturn, Uranus, and Neptune. The size of these outer planets is huge so is their gravity.
Because of their huge gravity a lot of matter which was scattered in the outer solar system got attracted towards them. This matter is what make the rings of the outer planets. Also, because of immense gravity they captured larger bodies thus making them their Moons.
Answer:
808.25 seconds
Explanation:
From the relation,
If t = time
v = velocity
l = length
The current density, J, of a charge is given by:
Where number of charge carriers per unit volume n = 8.49 * 10²⁸
Charge of the electron, q = 1.6 * 10⁻¹⁹
Cross sectional area of the wire, A = 0.21 cm² = 0.000021 m²
Equating (1) and (2)
Since t = l/v.......(3)
Put the formula for v into equation (3)
t = 808.25 seconds
Answer:
7.4 m
