Which of the following are other rationing mechanism that emerge when a binding price ceiling is imposed in a market? (Select all that apply)

Two point charges are on the x-axis.  Charge q1 = 5.00 uC is at the origin and q2 = -3.00 uC is at x = 0.350 m.  b)  Find the direction of the electric field at a distance of 0.450 m directly above q2.

Two point charges are on the x-axis.  Charge q1 = 5.00 uC is at the origin and q2 = -3.00 uC is at x = 0.350 m.  a)  Find the magnitude of the electric field at a distance of 0.450 m directly above q2.

Two point charges are on the x-axis.  Charge q1 = -4.00 uC is at the origin and q2 = 3.00 uC is at x = 0.500 m.  a)  Find the magnitude of the electric potential at a distance of 0.350 m directly above q2.

A 6.70 uC point charge is released from rest in an electric field. If the mass of the charge is 0.00580 kg, and it gains a speed of 18.0 m/s as a result, what potential difference did the charge move through?

A flat rectangular loop of wire is placed between the poles of a magnet. It has dimensions w = 0.60 m and L = 1.0 m, and carries a current I = 2.0 A. The magnetic field due to the magnet is uniform and of magnitude 0.80 T. The loop rotates in the magnetic field and at one point the plane of the loop makes a 30° angle with the field. At that instant, what is the magnitude of the torque acting on the wire due to the magnetic field?

An electron moves with a speed of 8.0 × 10^6 m/s along the +x-axis.  It enters a region where there is a magnetic field of 2.5 T, directed at an angle of 60° to the +x-axis and lying in the xy-plane.  Calculate the magnitude of the acceleration of the electron. (e = 1.60 × 10^-19 C, me1 = 9.11 × 10^-31 kg)  

If the nominal interest rate is 5% and the rate of inflation is 10%, the real interest rate is

A cheetah leaps horizontally off a cliff with a speed of 6.30 m/s.  The cheetah lands a horizontal distance of 17.6 m from the base of the cliff. a) How fast is the cheetah going right before it lands?
