Analyze the data to identify the mathematical relationship between the amplitude and energy of a mechanical wave. If mechanical wave A has an
amplitude of 2 cm and mechanical wave B has an amplitude of 3 cm, what
will be the relationship between the energy carried by the two waves?
Amplitude
Energy
A. Wave A has about 2.5 times more energy than wave B.
B. Wave A has about 2.25 times more energy than wave B.
C. Wave B has about 2.25 times more energy than wave A.
O D. Wave A has about 1.5 times more energy than wave B.

Determine el momento angular de un rueda de 3000g moviendose a 10m/s con un radio de giro de 400cm

What distance does a car travel as its speed changes from 0 to 20 m/s in 17 s at constant acceleration?

In an old-fashioned amusement park ride, passengers stand inside a 3.0-m-tall, 5.0-m-diameter hollow steel cylinder with their backs against the wall. the cylinder begins to rotate about a vertical axis. then the floor on which the passengers are standing suddenly drops away! if all goes well, the passengers will “stick” to the wall and not slide. clothing has a static coefficient of friction against steel in the range 0.60 to 1.0 and a kinetic coefficient in the range 0.40 to 0.70. part a what is the minimum rotational frequency, in rpm, for which the ride is safe? express your answer using two significant figures. f f = rpm
