A person prevents a 7,500N car with its brakes released from moving on a hill by pushing the car uphill with a force of 25,000N for 2 seconds. How much work is done?

falling water hydro = water .. spectcular places these plants are

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this

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.
