Answer:
the answer is the spinning of the moon lets us see different amounts of light
Explanation:
you wanna know why uh yes ok lets cut to the magic so when the moon.
That's true.
Newton's law of universal gravitation says that the gravitational
force between two objects is
F = G · M₁ · M₂ / D² .
There's no note under the equation that says "only up to
this certain distance, and zero any farther than that".
The equation is true no matter how gigantic the distance
is between the objects.
Answer:
Explanation:
Given
Required
Determine the density
First, we need to convert mass to kg
Next, we need to convert volume to m^3
Density is then calculated as follows:
H = v 0 y 2 2 g . h = v 0 y 2 2 g . This equation defines the maximum height of a projectile above its launch position and it depends only on the vertical component of the initial velocity.
Answer: 45000 m/s^2
Explanation:
First, we know:
Bullet's Initial Velocity (Vo) = 0 m/s
Distance Travelled (D) = 1 m
Final Velocity (Vf) = 300 m/s
We need to know the bullets acceleration to reach the final velocity on that distance. Because the bullet stars from rest, his Initial Velocity is equal to zero.
We dont know on how much time it takes for the bullet, but we know the acceleration on the barrel is constant.
We can use the following equation for this
Because Vo is zero, the equation simplify, so we have.
Searching for the accelaration we obtain
Changing values
This is the acceleration needed to reach the velocity at the end of the barrel.
