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
