We now have two tappers that are tapping the surface of the water together. They are tapping in sync (both are hitting the surfa

ce at the same time). A small cork is sitting in the tank at the position of the small brown circle. As the stars continue to tap and the ripples from each star continue to move outward, what will happen to the cork

Answer:

The cork moves up and down.

Explanation:

The cork moves up and down because of the waves produce due to tapping the surface of water. The cork experience movement due to placed on the water surface so when the wave passes through the medium by tapping of water, movement of cork also occur. Cork has high volume and lower mass so it floats on the water surface and experience movement due to waves.

Why would it be desirable to use an energy resource that does not produce greenhouse gases?
Art [367]

C. Greenhouse gases contribute to climate change

Explanation:

It is desirable to use an energy source that does not produce greenhouse gases because these gases contributes a whole lot to climate change.

Over the years, studies have shown that the primary use of fossil fuels have significant lead to changes in the climate.

  • Greenhouse gases are produced during the combustion of fossil fuels.
  • The most important gas produced in this process is the carbon dioxide.
  • The greenhouse gases prevents long range radiation from leaving the earth.
  • They waves interacts with the gases and warms the earth surface.
  • Anomalous concentration of the gases causes more warming of the earth surface.
  • This leads to a change in climate.

. A 1.00 kg rock is thrown up into the air from ground level at a speed of 8.00 m/s. The ball travels up
Liula [17]

Answer:

p = -8 kg-m/s

Explanation:

Given that,

Initial speed of the rock, u = 8 m/s

Mass of the rock, m = 1 kg

The ball travels up  to a maximum height, then returns to the ground.

We need to find the rock's momentum as it strikes the  ground. Let v be the final speed of the rock. Its final speed is as same as initial speed i.e. 8 m/s but in negative direction. So

p = mv

p = 1 kg × (-8 m/s)

= -8 kg-m/s

So, the rock's momentum as it strikes the  ground is (-8 kg-m/s).
