A car speeds at 21.5 m/s. The force of resistance remains constant at 375 N during this time. What is the average power developed by the car’s engine?

answer; (d) spontaneous processes are characterized by the overall conversion of order to disorder;

the ima (higher than 1m) will be greater than the ima with the height of 1m.

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.
