The formula of Momentum should be used; P=mv, we’ve known the number of the momentum(P) and mass(m), and then we can find velocity(v).
Answer:
The acceleration of a 2 kg box acted on by a net force of 2 N is solved by using Newton’s second law of motion in the form acceleration = F_net / mass. Since the mass of the box is 2 kg and the net force is 2 N, the acceleration of the 2 kg box is 1 m/s^2.
The appropriate response is Emotion-centered coping. It is a particular system that was produced in the 1980s by the clinicians Susan Folkman and Richard Lazarus, and these methods concentrate on changing one's passionate response to an unpleasant or disquieting circumstance, for example, getting a finding of a terminal disease.
Answer:
The planet that is farther from the star must have a time period greater.
Explanation:
We can determine the ratio of the period's planet with the radius of the circular orbit in the star's equatorial plane:
(1)
Where:
r: is the radius of the circular orbit of the planet and the star
T: is the period
G: is the gravitational constant
M: is the mass of the planet
From equation (1) we have:
(2)
Where k is a constant
From equation (2) we have that of the two planets, the planet that is farther from the star must have a time period greater.
I hope it helps you!
