During football practice, a football is kicked with a speed of 22 m/s at an angle of 60.0° relative to the positive x direction.

If you observe people moving by you at very high speed, you will say that their time runs slowly, their lengths are contracted in the direction of motion, and their masses are increased from their rest masses. What will they say about you?

How are the electric field lines around a positive charge affected when a second positive charge is near it?

How does the electric force between two charged particles change if the distance between them is decreased by a factor of 3?

Which best states the author's argument in catching sun rays? no power source is clean, free, and renewable. it costs too much to use solar energy for power. the use of solar energy can cause blackouts in big cities.
