Answer:
9.4 x 10⁴ m/s
Explanation:
In circular or elliptical orbits , the angular momentum is conserved because torque is zero.
mr₁v₁ = mr₂v₂
2.2 x 10¹¹ x 1.8 x 10⁴ = 4.2 x 10¹⁰ v₂
v₂ = 9.42 x 10⁴ m/s.
= 9.4 x 10⁴ m/s
The muscular system is responsible for controlling the skeletal muscles and the muscles of the internal organs, including the heart, stomach and intestines. It connects with the nervous system and receives input from efferent neurons, allowing it to respond to external or internal stimuli.
