when an electron travels at a speed of 1.00 x 10^3 m/s it has a wavelength of 727 nm. what would be the wavelength of hydrogen molecule when it travels with the same speed

What are the necessary conditions for fusion?

The electric field direction is defined by the direction of the force felt by (select one of the following answers): 1. a negative charge. 2. a positive charge. 3. both positive and negative charges.

In a system with only a single force acting upon a body, what is the relationship between the change in kinetic energy and the work done by the force? answers: work is equal to the change in kinetic energy.work depends on the square of the change in potential energy.work is equal to the negative of the change in kinetic energy.work is equal to the square of the change in kinetic energy
