Give three properties that are the same for radio waves and microwaves

They travel at the same speed through air.They travel at the same speed through a vacuum.They are both transverse waves. Other answers that are accepted: they can be reflected, refracted, diffracted, and abs...

Draw a distance-time, speed-time, and acceleration-time graph for an object moving at a constant velocity of 5m/s for 10 seconds.

We know that the object is moving at 5m/s already telling us that the distance the object has travelled increases with time. Plotting distance on the y axis against time on the x axis we therefore expect a s...

A typical question is about energy transfer - Explain the process of convection and give an example of where we can find them

Molecules in the air encounter an energy source, they gain energy and begin to heat up which causes them to vibrate faster and become less dense which causes them to rise. As they rise, they begin to lose en...

How does Ice make drinks Ice cold?

Ice, in it's solid form, is at a maximum temperature of zero degrees Celsius. You might expect that a small volume of Ice might cool say a 25 degree drink to somewhere halfway between 0 and 25. This is not o...

a) A car weighs 1500kg, if it is travelling at 7m/s, how much kinetic energy does it have?

To determine the kinetic energy of the car, we need to use the formula for kinetic energy. The formula is KE=(1/2)mv^(2) where m is the mass of the object (in kg) and v is the speed of the object (in meters ...
