Answer:
At the very bottom, whnere the sag is the greatest, Jay’s acceleration is upward.
Explanation:
As Jay lands on the trampoline, Jay’s motion was dowward, the trampoline was opposing his motion and hence, caused him to reach an initial halt position. Afterwards, the trampoline causes Jay to move back into the air and therefore, the change in velocity vector act in upward direction. The acceleration vector is always align towards the change in velocity vector's direction.
Visibly you can see that the two copper are different sizes so the mass and volume are different. No information is given about the temperature but they are side by side so you can assume they're both room temp. The density is a ratio of mass per volume. The density will remain the same unless the two are different purities or physical states.
Answer:
Both of the stunt professionals will sustain injuries of the same seriousness
Explanation:
We are being told that both stunt professionals are standing from the same height, therefore they will attain the same equivalent speed at the bottom if we are to look at it from the principle of conservation of energy.
Now; According to principle of momentum; the momentum at which the first stunt professional A hits the ground be equal as the momentum with which stunt professional B will hit the wall.
Thus; both of the stunt professionals will sustain injuries of the same seriousness
<h2>Answer:</h2>
- Circuit A is a series circuit
- The total resistance in Circuit A is greater than that in Circuit B
<h2>Explanation:</h2>
A series circuit is a closed circuit in which the current follows in only one path. In a series circuit, the current through each load is the same and the total voltage across the circuit is the sum of the voltages across each load. If one component of a series circuit becomes nonfunctional, the rest of components do not work. So the circuit A is a series circuit.
Explaining the second statement :
Each resistor in a series circuit has the same amount of current flowing through it, whereas the current flowing through each resistor in a parallel circuit is different, depending on the resistance. So we can say that when resistors are connected in parallel, more current flows from the source than flow for any of them individually, so the total resistance is lower.
