A crate is pushed up a ramp at an angle of 30 degree by a 300 N force. How much power is spent in raising the crate to a height

of 0.98 m 15s ? Assume that the coefficient of friction between the surfaces of the crate and ramp is 0.30 and the crate moves up the ramp at a constant speed.

What is the gravitational force between two 1 kg objects that are 1 m apart?
lapo4ka [179]

Answer:

F=6.67\times 10^{-11}\ N

Explanation:

Given that,

The masses of two objects, m₁ = m₂ = 1 kg

The distance between masses, d = 1 m

We need to find the gravitational force between two masses. The force is given by the relation as follows :

F=G\dfrac{m_1m_2}{d^2}\\\\F=6.67\times 10^{-11}\times \dfrac{1\times 1}{(1)^2}\\F=6.67\times 10^{-11}\ N

So, the force between two masses of 1 kg is 6.67\times 10^{-11}\ N.

A cyclist is riding his bike up a mountain trail. When he starts up the trail , he is going 8 m/s. As the trail gets steeper, he
Mrac [35]

Acceleration = (change in speed) / (time for the change)

change in speed = (speed at the end) - (speed at the beginning)

Our cyclist's change in speed = (3 m/s) - (8 m/s) = -5 m/s

Acceleration = (-5 m/s) / (60 seconds)

<em>Acceleration = -1/12 m/s²</em>

Correlation alone_____ causation A.proves B.complicates C. Disproves D. does not prove
tatuchka [14]

Answer:

D.

Explanation:

This is the essence of “correlation does not imply causation”. When there is a common cause between two variables, then they will be correlated. This is part of the reasoning behind the less-known phrase, “ There is no correlation without causation ”.

Why is Radiology important in the medical field?
juin [17]

Answer:

Radiology plays a huge role in disease management by giving physicians more options, tools, and techniques for detection and treatment. Diagnostic imaging allows for detailed information about structural or disease-related changes. With the ability to diagnose during the early stages, patients may be saved.

A car initially at rest undergoes uniform acceleration for 6.32 seconds and covers a distance of 120 meters. What is the approxi
Alja [10]
The approximate acceleration of the car would be <span>3.00

</span>How? We have to use the formula to find the velocity.

v = d/t = 120/6.32

v = 19

Then plug the factor into the acceleration formula to find the acceleration:

a = v/t = 19/6.32

a = 3.00

So, the approximate acceleration of the car would be 3.00
