The best answer would be A
Answer:
A. Rocket A will travel farther horizontally than rocket B.
Explanation:
This is because from the x axis, 40 m/s at 90 degrees travels directly vertical. 40 m/s at 70 degrees is slightly horizontal, so it will travel further horizontally.
Answer:
The magnitude of the magneticfield B[T] at a point on the surface of the earth directly below the power line is B=1.496x10^(-6) T.
Explanation:
The distance from the wire to a point in the surface is the heigth of the wire.
The formula for the magnetic field on any point at distance R from a wire conducting alternating current is:

<span>a 205 kg mass object will weight 1143.43 lbs on Jupiter.
Looking up the surface gravity of Jupiter, you can find that it's 2.53 times that of earth. So the 205 kg object will weigh
205 * 2.53 = 518.65 kg on Jupiter.
Now we need to convert from kg to pounds. This is done by multiplying by 2.20462
518.65 kg * 2.20462 lb/kg = 1143.43 lb</span>
