B. Reversing the current direction will cause the force deflecting the
wire to be perpendicular to the magnetic field but in the opposite
direction.
Answer:
v₂ = 48 mph
Explanation:
We know that,
Speed = distance/time
A German Shepherd takes 4 hours to cover a distance, if it travels at a speed of 36mph.
We need to find the speed to cover the same distance in 3 hours.
So, the new speed is 48 mph.
A. What is force because yeah are using force to pull back on the bow
For this item, I assume that the speed being talked about is that of falling objects. If the object is farther away from the Earth's center, the gravitational energy will have very little effect on it. The speed will therefore be little less.
Answer:
50.67
Explanation:
L = 4 m
Let the mass of small length dx is dm.
So, dm = ρ(x) dx
Integrate on both the sides within proper limits
m = 40 + 32 / 3 = 152 / 3 = 50.67
