A block is on a frictionless table, on earth. The block accelerates at $5.3\text{}\frac{m}{{s}^{2}}$ when a 10 N horizontal force is applied to it. The block and table are set up on the moon. The acceleration due to gravity at the surface of the moon is $1.62\text{}\frac{m}{{s}^{2}}$. A horizontal force of 5N is applied to the block when it is on the moon. The acceleration imparted to the block is closest to:

a) $2.9\text{}\frac{m}{{s}^{2}}$

b) $3.2\text{}\frac{m}{{s}^{2}}$

c) $3.4\text{}\frac{m}{{s}^{2}}$

d) $2.7\text{}\frac{m}{{s}^{2}}$

e) $2.4\text{}\frac{m}{{s}^{2}}$

An exceptional standing jump would raise a person 0.80 m off the ground. To do this, what force must a 66-kg person exert against the ground? Assume the person crouches a distance of 0.20 m prior to jumping, and thus the upward force has this distance to act over before he leaves the ground.

Four very long, current-carrying wires in the same plane intersect to form a square with side lengths of 45.0 cm, as shown in the figure blelow. The currents running through the wires are 8.0 A, 20.0 A, 10.0 A, and I.

Part A

Find the magnitude of the current I that will make the magnetic field at the center of the square equal to zero.

Part B

What is the direction of the current I (up or down)?
