A spring on a horizontal surface can be stretched and held 0.2 m from its equilibrium position with a force of 16 N. a. How much work is done in stretching the spring 3.5 m from its equilibrium position? b. How much work is done in compressing the spring 2.5 m from its equilibrium position?

a  

b  

Explanation:

Generally the force constant is mathematically represented as

substituting values given in the question

=>  

=>  

Generally the workdone  in stretching the spring 3.5 m is mathematically represented as

=>    

=>    

Generally the workdone  in compressing the spring 2.5 m is mathematically represented as

=>      

=>      

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.

im sorry i dont know
