Answer:
F = 48 [N]
Explanation:
To solve this problem we must use Newton's third law, which tells us that the sum of forces on a body must be equal to zero, that is, the body is in static equilibrium or in equilibrium.
ΣF = 0
24 + 24 - F = 0
F = 24 + 24
F = 48 [N]
Note: Jeff's force should be equal to the sum of Sally and Misha's forces, but in the opposite direction.
The slope of an object is given relative to an origin.
Answer:
F = 29.484 N
Explanation:
The force on the rod can containing the current placed in external magnetic field is:
F = BIL
where,
B = magnitude of the field
I = current in the loop
L = length
then,
F = 7.80 * 18.0 * 0.21
F = 29.484 N
The correct answer is A: controlled for useful work
