Momentum can be defined by the formula p=m*V (where m is mass and V is velocity) so if we plug in these numbers:
p = 2kg * 6m/s
p = 12 kgm/s
Answer:
As the distance between a satellite in a circular orbit and the central object increases, the period of the satellite <em>increases</em> .
Explanation:
Answer:
Option C is correct.
Explanation:
Force between two charges = k q₁q₂ / r² , k is constant q₁ , q₂ are charges with separation of r .
= (9 x 10⁹ x 2.5 x 10⁻⁵ x 2.5 x 10⁻⁵) / .5²
= 56.25 x 10⁻¹ / .25
= 22.5 N
23 N .
Force will be attractive as the charges are opposite in nature .
