<span>umm it gives 1/v + 1/20 = -1/10 and v = -20/3 cm. Magnification = |v/u|=1/3.</span>
Answer with Explanation:
We are given that
Mass of rock=m
Maximum height=h
a.At maximum height, velocity,v=0
We know that
Height,h=h/4
Again,
Where
b.When height,h=3h/4
Answer:
Explanation:
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
M = Mass of the star
m = Mass of object at a distance r
r = Radius = 25 km
N = 14 rev/s
The gravitational force of will balance the centripetal acceleration
Velocity is given by
The mass of the neutron star is
Answer:
B
Explanation:
the reason the small turtle has more momentum is because it was less an example is I have two rocks a rock that weighs 1 oz and another rock that weighs half a pound the one that is half a pound Falls faster in the one that weighs an ounce Falls last hopefully that makes sense
