The current in an alternating circuit varies in intensity with time. If I
represents the intensity of the current and t represents time, then the relationship between
I and t is given by  where I is
measured in amperes and t is measured in seconds. Find the maximum value of I and the
time it takes for I to go through one complete cycle. a. | The maximum value of I is 20 amperes; one complete cycle takes 
seconds. | b. | The maximum value of I is 160 amperes; one complete cycle takes  seconds. | c. | The maximum value of I is 40 amperes;
one complete cycle takes  seconds. | d. | The maximum value of
I is 20 amperes; one complete cycle takes  seconds. | e. | The maximum value of
I is 40 amperes; one complete cycle takes

A weight is hung from a spring and set in motion so that it moves up and down
continuously. The velocity v of the weight at any time t is given by the equation
 where v is measured in meters per
second and t is measured in seconds. Find the maximum velocity of the weight and the amount of
time it takes for the weight to move from its lowest position to its highest position. a. | The maximum velocity is 5.5 meters per second ; the time it takes for the weight to
move from its lowest position to its highest position is  seconds. | b. | The maximum velocity
is 5.5 meters per second ; the time it takes for the weight to move from its lowest position to its
highest position is  seconds. | c. | The maximum velocity
is 22 meters per second ; the time it takes for the weight to move from its lowest position to its
highest position is  seconds.. | d. | The maximum velocity
is 22 meters per second ; the time it takes for the weight to move from its lowest position to its
highest position is  seconds. | e. | The maximum velocity
is 4.5 meters per second ; the time it takes for the weight to move from its lowest position to its
highest position is  seconds. |
