Select the correct answer. A perlodic wave travels from one medlum to another. Which palr of varlables are likely to change In the process?
OA velocity and wavelength
OB. velocity and frequency
OC. frequency and wavelength
OD. frequency and phase
OE. wavelength and phase

velocity and wavelength likely to change in the process.

Explanation:

When an object passes from one medium to another, refraction occurs. Due to refraction, it changes iits direction. Some of the properties is changed when it undergoes refraction. The velocity of a wave and wavelength change in this process.

Hence, the correct option is (a) "velocity and wavelength".

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.
