:)
a wave with a frequency of 600 hz is traveling at a speed of 200 m/s.
what is its wavelength?
a. 3 meters b. 1200 meters c. 0.75 meters d. 0.33 meters

i think the answer is a and b

i wish you luck

t = 1/400 h   ⇔ 0.0025 h ⇔ 9s ⇔ 0.15 m

any of the answers are correct.

explanation:

to push or pull an object in a certain direction is known as force. a force in moving an object from one place to another.

force depends on the mass of an object. so, more is the mass of an object more will be the force required to move the object.

thus, we can conclude that the use of force to move an object is push or pull.
