46) A bicyclist riding at 12 km/h doubles her speed traveling along a flat trail Which statement most accurately describes
a graph of her kinetic energy from the time she increases her speed?
A)
a straight line with y intercept at zero and a positive slope
B)
a parabolic line with y intercept at zero and a positive stope
C)
a straight line with y intercept at the kinetic energy when her speed is
increased, with a positive slope
a parabolic line with y intercept at the kinetic energy when her speed is
increased with a positive slope
D)

At a certain instant after jumping from the airplane a, a skydiver b is in the position shown and has reached a terminal (constant) speed vb = 52 m/s. the airplane has the same constant speed va = 52 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius ρa = 2330 m. (a) determine the velocity and acceleration of the airplane relative to the skydiver. (b) determine the time rate of change of the speed vr of the airplane and the radius of curvature ρr of its path, both as observed by the nonrotating skydiver.

What does si stand for, when referring to a system of measurement

Aloop of wire is in a magnetic field such that its axis is parallel with the field direction. which of the following would result in an induced emf in the loop? choose all that apply. a loop of wire is in a magnetic field such that its axis is parallel with the field direction. which of the following would result in an induced emf in the loop? choose all that apply. moving the loop outside of the magnetic field region. spin the loop such that its axis does not consistently line up with the magnetic field direction. change the magnitude of the magnetic field. change the diameter of the loop
