A student in the lab has a 17 kg mass attached to a horizontal spring on a frictionless track as shown. The position labeled "O m" represents the unstrained position of the spring. The student initially moves the block so that it compresses the spring,
where the initial position is shown. The student releases the block from rest and starts a timer. The block moves to the
maximum position shown before returning to its initial position. The student counts the number of times that the block
returns to its initial position and finds that it takes 25.9 s for the block to return 14 times.

What is the magnitude of the maximum acceleration for this object in m/s2)?

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.

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
