A bowling ball has a mass of 7.2 kg and a weight of 70.6 N. It moves down the bowling alley at 1 m/s and strikes a pin with a force of 15.0 N. What is the force that the pin exerts on the bowling ball?
The answer is: 15.0 N
Answer:
Explanation:
The choices for this question are
Givens
However, to solve this we just need to use Newton's third law which states: "When an object exerts a force on another object, the second object will exert an equal and opposite force to the first object".
If the bowling ball strikes a pin with a force of 15N, then the pin will exert the same 15N on the bowling ball, but with the opposite direction. If the bowling force is positive, then the pin force will be negative.
Therefore, the right answer is the second choice 15N.
B. store electric charges.
C. increase circuit power.
D. measure the amount of current in the circuit.
Answer: B. store electric charges.

Answer:
Hydrogen and helium compounds.
Explanation:
We know that the solar System was formed around 4.6 billion years ago, due to the gravitational collapse of a giant interstellar molecular cloud.
This cloud is a type of interstellar cloud and its density and size permit the formation of molecules, most commonly molecular hydrogen.
Therefore the principal substances were found before planets began to form are hydrogen and helium compounds, besides Rocks, metals, most of them in gaseous form.
