A very powerful vacuum cleaner has a hose 2.36 cm in diameter. With no nozzle on the hose (no change to hose area), what is the

weight of the heaviest brick it can lift? The atmospheric pressure is 1.00 atm=101,300 Pa. Ignore the buoyancy force of the air on the brick.

Answer:

Explanation:

Pressure=Force/Area

Force=Pressure * Area

Force=1.013\times 10^5 \times 3.14\times (1.03\times 10^{-2})^2\\\\=33.7N

How are a wave's energy and the wave's amplitude related?
dem82 [27]
Answer:
Energy is proportional to the square of the amplitude

Explanation:
The energy of a certain wave is defined using its magnitude.
The two quantities are related directly. This means that as the amplitude of the wave increases, its energy increases and vice versa.

Energy is directly proportional to the square of the magnitude of the wave. This means that:
If we have new amplitude = 2 * old amplitude
We will have new energy = (2)² * old energy = 4 * old energy

Hope this helps :)
