Answer:
1 . What happens when you drop the stone?
Depending on the weight from which the stone was dropped, the glass might well break
2 depending on the size and weight and shape on the stone the glass might well break
3 depending on the density on the stone the stone might when float on the water

Answer:
solution:
to find the speed of a jogger use the following relation:

Here C =constant of integration.

now we have the relation to find the position and time for the jogger as:

Here
x is measured in miles and t in hours.
(a) To find the distance the jogger has run in 1 hr, we set t=1 in equation (2),
to get:

differentiate
equation (1) with respect to time.
we have to eliminate x from the equation (1) using equation (2).
Eliminating x we get:

Answer: 13.2678 kg
Explanation: Well, 13.2678 kg is 29.25 in mass and kg.
Answer:The actual answer is heat.
Explanation:There is always water under a forming hurricane, the strength of the hurricane depends on the heat of the water since heat is a raw form of energy. It can transfer to the storm.
Answer:
(answer a)
Explanation:
Recall the formula for the Coulomb force:
which in our case gives:
which agrees with answer a)
