Answer:
68.9233231661
Explanation:
Just put it into your calculator, shift sin should do it but it will come up like this: 
which is the same as arcsin
1 volt = 1 joule per coulomb
50 volts = 50 joules per coulomb
50 joules/coulomb times 6 coulombs = 300 joules
Bottom of the water tower
Explanation:
When holes are drilled through the wall of a water tower, water will spurt out the greatest horizontal distance from the hole closest to the bottom of the water tower.
This is because the near the bottom of the tower is the greatest compared to other parts of the tower.
- The pressure increases with depth.
- As the depth of water increases, the column of water above exerts more pressure on the one below.
- Therefore, water will spurt out more from the bottom of the tower compared to the top of the tower.

ANSWER:
250 J
STEP-BY-STEP EXPLANATION:
F = 20N is required to stretch the spring by 4 meters
We know that the force is equal to:
We solve for k (spring constant):
The work done in stretching the spring is given by the following equation (in this case the stretch is 10 meters:
The work required is 250 joules.
Answer:B
Explanation:
Calculate speed using equation:V=S/t
S=980 km ------------ distance Boston-Detroit
t=2h --------------------- time
v=?
------------------------
V=S/t
V=980km/2h
V=490km/h
