These are the Kepler's laws of planetary motion.
This law relates a planet's orbital period and its average distance to the Sun. - Third law of Kepler.
The orbits of planets are ellipses with the Sun at one focus. - First law of Kepler.
The speed of a planet varies, such that a planet sweeps out an equal area in equal time frames. - Second law of Kepler.
Needs mass to be reasonably solvable, sorry
A.) True. Momentum is the mass of an object multiplied by its velocity.
It is defined as a mass in motion. It refers to the quantity of motion an object has.
Answer:
a = 40 [m/s²]
Explanation:
These kinds of problems can be solved using Newton's second law, which tells us that the sum of forces on a body is equal to the product of mass by acceleration.
∑F = m*a
where:
F = force = 6 [N]
m = mass = 0.15 [kg]
a = acceleration [m/s²]
![a=F/m\\a=6/0.15\\a=40[m/s^{2} ]](https://tex.z-dn.net/?f=a%3DF%2Fm%5C%5Ca%3D6%2F0.15%5C%5Ca%3D40%5Bm%2Fs%5E%7B2%7D%20%5D)
Answer:
Period is 1.57 seconds
Explanation:
From simple harmonic motion :

T = 2π√(2.5÷10)
T = 0.25 × 2π
T = 1.57 s
