Answer:
Explanation:
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
= Mass of sphere = 2000 kg
= Mass of other sphere = 2.1 kg
r = Distance between spheres
Force of gravity is given by
The gravitational force is
The gravitational force is
Physical change
Because it's changed by heat
Alkaline earth metals are found in group 2
Even though im ot giving you the whole answer I can tell you what to do and why to do it. If what you need is to find the Electric field of something you need to use the formula for that wich is E = kQ/r2 where k is a constant with a value of 8.99 x 109<span> N m</span>2/C2., Q is <span>a charge of magnitude and you have also the ratio. So replace the simbols with the data they give you. I know thi will help you</span>
Answer:
v = 98.4 m/s
Explanation:
As we know that the total angular momentum of the system is conserved
so here we will have
now plug in all data
