Question

part A.) A producer wants to move a bridge prop with oscillating springs to another planet, hoping that it will make the oscillations change their period and thereby signifying to viewers there is a change in location. What do you tell him?

-answer choices

a.) The periods of the spring oscillations would not change appreciably unless the gravity on the planet were twice as large or twice as small as that on earth.

b.) The periods of the spring oscillations would not change.

c.) Viewers are too science illiterate to understand why the periods of spring oscillation are changing.

part B.)The same producer (unfortunately) tells you that he does not care about scientific accuracy. He just wants the springs to oscillate more rapidly.  twice as fast to be exact. Being the employee, you rapidly suggest that this can be achieved by:

-answer choices

a.) Increasing the m and k both by a factor of 4.

b.) Increasing the mass by a factor of 4.

c.) Shipping the producer to another planet. (This will not work but it may be a tempting choice.)

d.) Increasing the spring constant by a factor of 4.

Answer 1

A) T= 25 T As the value of a becomes twice, then only we alserve an appreciable change in the value of T. B) me are rafudly - as twice, so time period becomes half. So, 72 20 minut - so, to make the time period half, k should be 4 times option (d)
