The mass of a mass-and-spring system is displaced 10 cm from its equilibrium position and released. a frequency of 4.0 hz is observed. what frequency would be observed if the mass had been displaced only 5.0 cm and then released?

f = 4.0 Hz

Explanation:

The frequency of SHM in spring mass system is given as

now we can see that the frequency of SHM of spring mass system depends upon following parameters

1) mass of the object

2) spring constant

So here it does not depends on the displacement of the object from its mean position

So here the frequency will remain the same

So here

f = 4.0 Hz

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 body's situation won't change the forces are equal opposit and on the same body
