Answer:
Explanation:
By energy conservation and work energy theorem we can say that after bullet hits the block, it will move on the rough floor and comes to rest
so here work done by frictional force = change in kinetic energy
so we know that
now by momentum conservation we have
This is because the pressure is so much larger at 3000 meters than it is at sea level. Hope this helps.
Answer:
4.91 years
Explanation:
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
M = Mass of star
v = Oribital velocity of star
T = Oribital time period
R = Radius of orbit
Mass of the star is
Orbital period of the faster planet is 4.91 years
