A periodic wave travels from one medium to another. Which pair of variables are likely to change in the process? A. velocity and
dezoksy [38]

Answer:

A. velocity and wavelength

Explanation:

  • When a wave travels from one medium to another it undergoes a change in direction and this is referred to as refraction.
  • Refraction is the bending of a wave or a change in direction of a wave as it travels from one medium to another. Refraction is accompanied by change in velocity and wavelength of a wave.
  • Velocity of a wave is proportional to the wavelength of the wave therefore, if the velocity of a wave changes the the wavelength will also change proportionally to the velocity.

A sound wave with a frequency of 300 hertz is traveling a medium at a speed of 320 meters/second. What is it’s wavelength
user100 [1]
Wavelength = (speed) / (frequency)

Wavelength = (320 m/s) / (300 / sec)

Wavelength = (1 and 1/15) m/s

Jeff is pushing a rock up a hill with a force of 85 N. If Chris comes to help and Chris can push with a force of 60 N, what is t
Oksanka [162]

Answer:

F = 145 N

Explanation:

Given that,

Force applied by Jeff is 85 N and the force applied by Chris is 60 N. Both forces are acting in the same direction to push a rock up a hill. It means that net force is equal to the sum of these two forces.

So,

Net force on the rock = 85 N + 60 N

= 145 N

Hence, the net force on the rock is 145 N.
