Answer:
No
Explanation:
Not all metals stick to magnets. Like aluminum. if you were to stick a magnet on to an aluminum it would fall off.
The relationship between the frequency and wavelength of a wave is given by the equation:
v=λf, where v is the velocity of the wave, λ is the wavelength and f is the frequency.
If we divide the equation by f we get:
λ=v/f
From here we see that the wavelength and frequency are inversely proportional. So as the frequency increases the wavelength decreases.
So the second statement is true: As the frequency of a wave increases, the shorter the wavelength is.
A. Wedge
and
B.Screw
A screw is like an inclined plane wrapped around a pole or rod.
and a wedge looks kind of looks like this / and is inclined.
Hope this helps!
Please mark me brainliest! Thanks!
Forces are needed to lift, turn, move, open, close, push, pull, and so on. When you throw a ball, you are using force to make the ball move through the air. More than one force can act on an object at the same time.
