It is the velocity of the object.
The correct answer is C. more mass and less distance between two objects.
The outward push of the core created by nuclear fusion and the inward pull of gravity from the core
Answer: 4.29 m/s
Explanation:
Given
Depth of the well, s = 8.23 m
Time taken to reach the well, t = 0.93 s
Speed of sound = 343 m/s
To solve this, we would be using one of l the laws of motion.
S = ut + 1/2gt², where
S = depth of the well
u = initial speed of toss
g = acceleration due to gravity
t = time taken to reach the well
We would then have
8.23 = 0.93 u + 1/2 * 9.8 * 0.93²
8.23 = 0.93 u + 4.9 * 0.8649
8.23 = 0.93 u + 4.23801
0.93 u = 8.23 - 4.23801
0.93 u = 3.99199
u = 3.99199 / 0.93
u = 4.29 m/s
Therefore, the initial speed of the coin is 4.29 m/s
The equal and opposite reaction to the gravitational force of the Earth pulling down on a man standing on the beach is the gravitational force of the man pulling up on the Earth. <em>(A)</em>
To put it in other words ... which should begin to blow your mind if you just take a moment to think about them ...
Your weight on Earth is exactly equal to the Earth's weight on YOU.
