V= frequency x wavelength
The average velocity of a microwave is 3x10^8m/s.
3x10^8m/s= (.05m) x frequency
f= 6x10^9Hz
Answer:
24mph
Explanation:
it really depends how high but the average speed for that quick will be atleast 24mph if not try 42mph if it is wrong
Answer:
This system uses angular momentum and torque to do work on objects, typically against the force of gravity. The wheel and axle simple machine is closely related to gears.
I thinks or know it is A or B cuz magnets and metal attract

<span>If both surfaces are convex the lens is thicker at its center than its edges. A lens with one surface convex and one concave is called meniscus. Some lenses change the direction of the rays enough to cause the rays in a bundle to emerge convergent, that is, converging toward a common point. Whatever the mix of surfaces, if the lens is thicker at its center than its edges it is called a converging lens (having positive focal length). If it is thinner at its center than its edges it is called diverging (having negative focal length).</span>
