In the equation for the gravitational force between two objects, the distance quantity or measurement must be squared. The formula for calculation the gravitational force between two objects is F = G*m1*m2/d^2. F is the gravitational force between the two objects. G is the constant gravity, m1 is the first object's mass, m2 is the second object's mass, and d is the distance between the two objects<span>.</span>

A 2-kg ball is moving with a speed of 4 m/s, and a 4-kg ball is moving with a speed of 2 m/s. What can you conclude about the of

Mila [183]

<h2>Kinetic energy of mass 4 kg ball is less than kinetic energy of mass 2 kg ball</h2>

Explanation:

Kinetic energy = 0.5 x Mass x Velocity²

For ball of mass 2 kg

Mass, m = 2 kg

Velocity, v = 4 m/s

Kinetic energy = 0.5 x 2 x 4² = 16 J

For ball of mass 4 kg

Mass, m = 4 kg

Velocity, v = 2 m/s

Kinetic energy = 0.5 x 4 x 2² = 8 J

Kinetic energy of mass 4 kg ball is less than kinetic energy of mass 2 kg ball

Two identical satellites orbit the earth in stable orbits. Onesatellite orbits with a speed vat a distance rfrom the center of t

Lelu [443]

Answer:

c) At a distance greater than r

Explanation:

If G= Gravitational constant

M= Mass of earth

r= distance from earth center

then orbital speed is ;

v = $\sqrt{\frac{GM}{r} }$

==> v²=GM/r

If speed of first satellite = V₁

==> V₁² = GM/r

==> r = GM/V₁²

If speed of second satellite say V₂ is less than V₁ then square of V₂ will be less than square of V₁ , and hence GM will be divided by less number in case of second satellite, and hence will give greater value of r as compared to first satellite.

So our answer is c
