The total mechanical energy is the sum of the kinetic energy and the potential energy. It is easier to solve for the potential energy in this case because we are given with the position of the apple.
PE = mgh
Substituting the mass, acceleration due to gravity and the height,
PE = (0.1 kg)(9.8 m/s²)(1 m) = 0.98 J
Then, we solve for the velocity at that point. The distance it had traveled is 0.5 meters.
d = v²/g ; 0.5 = v²/9.8 m/s²
v = 2.213 m/s
Then, solving for KE
KE = 0.5mv²
Substituting,
KE = 0.5(0.1 kg)(2.213 m/s)² = 0.245 J
Adding the two mechanical forces will give us an answer of 1.225 J. Thus, the answer is the first choice.
Answer:
CMB is landmark evidence of the Big Bang origin of the universe. When the universe was young, before the formation of stars and planets, it was denser, much hotter, and filled with an opaque fog of hydrogen plasma.
Answer:
Germanium
Explanation:
Germanium is a chemical element that is grayish white metalliod
Resistor X is the same material and thickness as resistor Y, but it is twice as long. The resistance of resistor X is double that of resistor Y.Option 2 is correct.
<h3>What is resistance?</h3>
Resistance is a type of opposition force due to which the flow of current is reduced in the material or wire. Resistance is the enemy of the flow of current.
The relation of the resistance with the length and thickness is;
For the given case;
Resistor X has the same thickness and is made of the same material as resistor Y but has twice the length. Resistor X has twice the resistance of resistor Y.
Hence,option 2 is correct.
