To solve that we get given that a wave generator produces three waves per second at a wavelenght of 1.2 meters.

To tackle this you can use the formula v= f * lambda (speed = frequency * wavelength)...

This can be solved in 2 main sections: the first to find the acceleration of the car, and then the second to find how long it spends accelerating. To find the acceleration, Newton's 2nd Law (F=ma) can be ...

Reflection: a wave hits a surface, and bounces back into the medium it was originaly in

Refraction: a wave enters a medium with a different refractive index to the original medium it was travelling...

A force is any influence that causes an object to undergo a specific change. Resulting unbalanced forces can cause changes in speed, shape or direction, whereas equal or balanced forces result in an equil...

This question asks students to recall the equation Work done = Force x Distance. 

In this question, students must multiply 200 by 5, with the answer being 1000 Joules. 

It is important that ...
