A single movable pulley is used to lift load of 4000N to the height of 50cm .If the efficiency of the pulley system is 75%, calculate the effort distance, effort applied, input work, output work and loss of energy in the simple machine.

he . if i may ask what i your question exactly?

explanation:

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.
