Name two examples of deposition.

2 answers:

The reverse of deposition is sublimation and hence sometimes deposition is called desublimation. One example of deposition is the process by which, in sub-freezing air, water vapor changes directly to ice without first becoming a liquid.

<span>some examples of deposition are when streams deposit sediments into deltas and alluvial fans.

Also, wind deposits sand when wind velocity decreases because it cannot carry enough particles

Next, glaciers deposit all sizes of sediment. They leave a big pile of rocks called moraine. Moraine usually is deposited in lakes called terminal moraines.

Lastly, water deposits sediments in an ocean bedrock into layers. The layers are based on the size of the particle. The bottom layer will be filled with large sediments and the top layer will be filled with loose sediments such as sand and pebbles.</span><span>

A 750-kg car moving at 23 m/s brakes to a stop. Assume that all the kinetic energy is transformed into thermal energy. The brake

ahrayia [7]

Answer:

The temperature of the brakes is 29.38°C.

Explanation:

Given that,

Mass of car = 750 kg

Speed = 23 m/s

Mass of iron = 15 kg

We need to calculate the kinetic energy of car

Using formula of kinetic energy

$K.E=\dfrac{1}{2}mv^2$

$K.E=\dfrac{1}{2}\times750\times23^2$

$K.E=198.375\ kJ$

We need to calculate the temperature of the brakes

Using formula of energy

$K.E=mc\Delta T$

Put the value into the formula

$198.375=15\times0.450\times\Delta T$

$\Delta T=\dfrac{198.375}{15\times0.450}$

$\Delta T=29.38^{\circ}C$

Hence, The temperature of the brakes is 29.38°C.

What is The force of gravity between the Aeneas and earth

Margaret [11]

Answer:

Since Venus and Earth are almost the same size and have about the same mass, the surface gravity on Venus is almost the same as the surface gravity on Earth. The surface gravity on Venus is about 91% of the surface gravity on Earth, so if you weigh 100 pounds on Earth, you would weigh 91 pounds on Venus.

How is wave movement affected by the various mediums it may travel through?

Juliette [100K]

Answer:

speed is affected by the medium in wich the wave travels.

Explanation:

The speed of a wave is affected when traveling in different medium, depending on the medium in which the wave travels it can go faster or slower, or not even be able to travel in that medium.

For light waves, the denser the medium through which the wave travels, the slower it will go through it, as there is more resistance to the light particles.

And in waves like sound, which instead of particles is a vibration or disturbance in the medium, they travel faster in denser mediums such as metal, because the disturbance is transmitted more efficiently thanks to how close together that the particles are in the metal, This is why sound does not travel in a vacuum; there are not even particles to transmit the vibration.

A satellite is in a circular orbit around a planet. A second satellite is placed in a different circular orbit that is farther a

irinina [24]

The speed of the second satellite is less than the speed of the first satellite.

<h3>What is speed?</h3>

The speed of any moving object is the ratio of the distance covered and the time taken to cover that distance.

Given is a satellite is in a circular orbit around a planet. A second satellite is placed in a different circular orbit that is farther away from the same planet.

When the distance from the center of the orbit increases, the time to complete the orbit will be greater.

Thus, the speed of the second satellite is less than the speed of the first satellite.
