Which number would most likely increase if the amount of recycled materials decreased?

which of the laws of motion states to every action there is an equal but opposite reaction letter a Newton's first law see Newto

nataly862011 [7]

Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects.

What has to be different to allow refraction to occur?

lidiya [134]

A. the medium

For refraction to occur, there has to be change from one medium to another. For example rays of light would refract as the travel from air to water.

Nikolas had an idea that he could use the compressed carbon dioxide in a fire extinguisher to propel him on his skateboard.

Serggg [28]

Answer:

Newton's third law of motion

Explanation:

Newton's third law of motion: every action has an equal and opposite reaction. Nikolas is using the compressed carbon dioxide to push him on his skateboard. Once the gas is released, it applies force that'll push him in the opposite direction, forward.

Why can a strong man not hold a weight on a chain completely straight?

marysya [2.9K]

The strong man cant hold a weight on a chain completely straight due to the gravity and the mass of the chain/chair,

An electric motor spins at 1000 rpm and is slowing down at a rate of 10 t rad/s2 ; where t is measured in seconds. (a) If the mo

REY [17]

Answer:

a) The tangential component of acceleration at the edge of the motor at $t = 1.5\,s$ is -1.075 meters per square second.

b) The electric motor will take approximately 3.963 seconds to decrease its angular velocity by 75 %.

Explanation:

The angular aceleration of the electric motor ( $\alpha$ ), measured in radians per square second, as a function of time ( $t$ ), measured in seconds, is determined by the following formula:

$\alpha = -10\cdot t\,\left[\frac{rad}{s^{2}} \right]$ (1)

The function for the angular velocity of the electric motor ( $\omega$ ), measured in radians per second, is found by integration:

$\omega = \omega_{o} - 5\cdot t^{2}\,\left[\frac{rad}{s} \right]$ (2)

Where $\omega_{o}$ is the initial angular velocity, measured in radians per second.

a) The tangential component of aceleration ( $a_{t}$ ), measured in meters per square second, is defined by the following formula:

$a_{t} = R\cdot \alpha$ (3)

Where $R$ is the radius of the electric motor, measured in meters.

If we know that $R = 7.165\times 10^{-2}\,m$ , $\alpha = 10\cdot t$ and $t = 1.5\,s$ , then the tangential component of the acceleration at the edge of the motor is:
