Answer:
Less than 18000N
Explanation:
Given
This question will be answered using Newton's third law.
Understanding this law, it implies that reaction force is equal and opposite to the force exerted.
This implies that;
If the force exerted on the ball is 18000N
the force exerted is -18000N
So, the option that answers the question is less than 18000N because -18000N < 18000N
A. supplies energy to make charge flow
Current always returns to the negative terminal.
<u>Explanation</u>:
Current flows from a positive to a negative terminal. It is due to the flow of negative electrons to positive side. The current flows from a high potential to a low potential. There is high concentration of electrons at the positive terminal and low concentration at the negative terminal. When the circuit is complete the electrons move from a high concentration to low concentration i.e; from positive terminal to negative terminal.
Answer:
Answer is (C)
Explanation:
<u>For</u><u> </u><u>acceleration</u>
• If the motion is vertically, then acceleration is 9.8 m/s²
» Upward motion, acceleration is negative (-9.8)
» Downward motion, acceleration is positive (+9.8)
<u>For</u><u> </u><u>velocity</u>
You can see yourself in a mirror because light rays<span> bounce off its shiny surface. Light rays come from everything you can see, including yourself. You see things when </span>the light<span>rays from them enter yours eyes. Some of the light rays that come from yourself strike the mirror. The mirror reflects the rays because it is very smooth. The rays come back to your and enter your eyes.</span>
