Climates near the equator are warmer than at the poles because
the sun's rays have greater energy at the equator
the sun's rays are more concentrated at the equator
ice at the poles absorbs the sun's rays
the equator is near a low-pressure belt

3. a lunar exploration vehicle was created by a research team. it weighs 3,000 kg on the earth. it needs an acceleration of 10 m/s2 on the moon. in order to have the same acceleration, what will be the net force acting on the vehicle on the earth?

If anyonee has done the momentum lab practical in physics can you give me the answers i am s lostt rnn : (

Determine the net charge of the predominant form of arg at (a) ph 1.0, (b) ph 5.0, (c) ph 10.5, and (d) ph 13.5
