Answer:

wind

water movement

hill

stop light.

Explanation:

Remember that acceleration can be positive or negative, in this examples A stop light can create a negative acceleration because you need to hit te breaks in order to stop, wind and water movement and hill will cause the car to accelerate because of the going downhill and the effect of the water on the car, that would cause acceleration.

A wheel rotates with a constant angular acceleration of  rad/s2. During a certain time interval its angular displacement is  r

Hatshy [7]

Answer:

The angular velocity at the beginning of the interval is $\pi\sqrt{2}\ rad/s$ .

Explanation:

Given that,

Angular acceleration $\alpha=\pi\ rad/s^2$

Angular displacement $\theta=\pi\ rad$

Angular velocity $\omega =2\pi\ rad/s$

We need to calculate the angular velocity at the beginning

Using formula of angular velocity

$\alpha =\dfrac{\omega^2-\omega_{0}^2}{2\theta}$

$\omega_{0}^2=\omega^2-2\alpha\theta$

Where, $\alpha$ = angular acceleration

$\omega$ = angular velocity

Put the value into the formula

$\omega_{0}^2=(2\pi)^2-2\times\pi\times\pi$

$\omega=\sqrt{2\pi^2}$

$\omega_{0}=\pi\sqrt{2}\ rad/s$

Hence, The angular velocity at the beginning of the interval is $\pi\sqrt{2}\ rad/s$ .

When beavers inhabit an area, they cut down trees and construct beaver dams, which slow the flow of rivers or streams. Which of

Airida [17]

Answer: H

Explanation:

When beavers dam a stream they slow the movement of water. Behind the beaver dam, a pond of still water is formed. This pond is then colonized by animals and plants that typically live in lakes rather than streams.

Which is evidence that a convergent boundary once existed

Vladimir79 [104]

Volcanic islands, Mountain ranges

Explanation:

A convergent margin is plate boundary in which plates comes together. There are different types of interactions that occurs around a place where plate converges.

An ocean-continent convergence creates a subduction zone in which the denser oceanic plate sinks beneath the less dense continental crust.
As the oceanic plate begins to subside, it can melt and form chains of volcanic island within the riding continents.
Also, where two plates of equal densities converge, none of them subsides and this leads to upbuilding.
The product can be seen as extensive mountain ranges on earth like the Andes and Himalayas.

During convection, heat warms up a fluid, making the fluid less dense so it begins to RISE. As the warm fluid moves, it begins t

Fiesta28 [93]

Answer:

True

Explanation:

Convection is a form of heat transfer that is predominantly common in fluids especially liquid and gas.

It occurs by the movement of a part of substance from one place to another based on density and temperature differences.

A typical convection cell is made up of a liquid that is heated. The liquid part close to the heat source becomes warmer and rises due to its low density. The part away from the heat source is more dense and begins to sink.

This analogy is commonly demonstrated in a boiling pot of water.
