Answer: See below
Explanation:
The Earth attracts the falling object with the same intensity of gravity as the object attracts the Earth, according to Newton's law of gravitation. The displacement of the two bodies, however, is inversely proportional to their respective masses.
Example: The Earth attracts a ball that falls 3 metres from the ground, even though the ball's mass is insignificant in comparison to the Earth's. Similarly, the ball draws the Earth with the same power, but the Earth's mass is enormously more than the ball's. As a result, the Earth collides with a billionth of a millimetre ball (or even less). Restart the Earth's descent on the ball you'll never see again.

Answer:
v = 0.33 m/s
Explanation:
The final velocity of the skier and boat can be calculated by conservation of the lineal momentum:
<u>Where:</u>
m1: is the mass of the water skier = 62.0 kg
m2: is the mass of the boat = 775 kg
v1i: is the initial velocity of the water skier = 4.50 m/s
v1f: is the final velocity of the water skier = ?
v2i: is the initial velocity of the boat = 0
v2f: is the final velocity of the boat = ?
Since the final velocity of the skier is the same that the final velocity of the boat, we have:
Therefore, the final velocity of the skier and boat is 0.33 m/s.
I hope it helps you!
Answer:
C
Explanation:
There are two forces on the table: weight and normal force. Newton's second law:
∑F = ma
N - mg = 0
N = mg
N = (23.5 kg) (9.81 m/s²)
N = 230 N
<span>That could be letter B: flowchart. Flowchart diagrams
can be used to easily service an electronic circuit board with ICs because they
let you see the flow of the current as you could imagine it. You can use
different shapes to further your explanation and illustration on how the
electricity flows from a source, to its medium to the switches. You could also
decide on flowcharts and be able to see where that decision leads you and you
could also try to learn different decision methods which is basically
illustrated on the chart.</span>
