What force is needed to give a 0.25-kg arrow an acceleration of 196 m/s2?

What is the speed of the sound wave if the frequency is 70 hertz and the wavelength is 0.4 meters

How did the electron change the model of the atom?

A world-class runner can complete a 100m dash in about 10s. past studies have shown that the runners in such a race accelerate uniformly for a time t (u) and then run at a constant speed for the remainder of the race.

Who made the very first solar cell and in what year?

What are some examples of tools or objects that apply force?

You push a 45 kg wooden box across a wooden floor at a constant speed of 1.0 m/s. The coefficient of kinetic friction is 0.25. Now you double the force on the box. How long would it take for the velocity of the crate to double to 2.0 m/s

A student in her physics lab measures the standing-wave modes of a tube. The lowest frequency that makes a resonance is 20 Hz. As the frequency is increased, the next resonance is at 60 Hz. What will be the next resonance after this? A. 80 Hz B.

For a satellite to stay in orbit around Earth, it has to be moving forward very fast all the time. What force will make it fall to Earth if it goes too slowly?
