An object of mass m is placed on Spring A, which is compressed by distance x. The spring is released and the velocity of the pushed object as it leaves the spring is measured. The experiment is repeated with the same object on Spring B, which is compressed by the same distance x. The object travels faster when pushed by Spring B. What can be concluded?

A. Spring A had a higher elastic potential energy than Spring B.

B. Spring A's spring constant is higher than Spring B's.

C. Spring A's spring constant is lower than Spring B's.

D. Spring A has more mass than Spring B.

i need with 1.3.2 investigate cycling o2 and co2 apex

we need to see it

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.

answer is slate

hope this
