Marco is conducting an experiment. he knows the wave that he is working with has a wavelength of 32.4 cm. if he measures the frequency as 3 hertz, which statement about the wave is accurate?

a. the wave has traveled 32.4 cm in 3 seconds.
b. the wave has traveled 32.4 cm in 9 seconds.
c. the wave has traveled 97.2 cm in 3 seconds.
d. the wave has traveled 97.2 cm in 1 second.

d.The wave has traveled 97.2 cm in 1 second.

Explanation:

As we know that the speed of the wave is given as

so we will have

frequency of the wave is given as

now we know that

so wave will travel 97.2 cm in 1 s

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
