Answer:

It's energy will double.

Explanation:

This is because energy, E, is related to frequency, f, by:

E = hf

Where h = Planck's constant

So, double frequency will be 2f

=> E(2f) = 2hf = 2E.

Hence, energy is doubled.

Describe what happens to the particles of a liquid, in terms of movement and kinetic energy, as it is cooled to its freezing poi
nataly862011 [7]
As a system is cooled to its freezing point, the kinetic energy of the particles in the system will lower so the movement are much slower. Cooling means taking out heat from the system. This process is a physical change because it is only the phase of the system is changed and it is still the substance after the process.

A 5.00 kg crate is on a 21.0 degree hill. Using X-Y axes tilted down the plane, what is the y-component of the normal force?
Rama09 [41]

Answer:

The y-component of the normal force is 45.74 N.

Explanation:

Given that,

Mass of the crate, m = 5 kg

Angle with hill, \theta=21^{\circ}

We need to find the y component of the normal force. We know that the y component of the normal force is given by :

F_y=F\ \cos\theta\\\\F_y=mg\ \cos\theta\\\\F_y=5\times 9.8\ \cos(21)\\\\F_y=45.74\ N

So, the y-component of the normal force is 45.74 N. Hence, this is the required solution.

A future space explorer has been kidnapped and is held prisoner on a planet in our solar system. With nothing else to do, our pr
DIA [1.3K]

To develop this problem we will apply the linear motion kinematic equations. Specifically, the second law that describes the position of a body as a function of its initial velocity, time and acceleration.

y = ut+\frac{1}{2}gt^2

Here,

u = Initial velocity

t = Time

g = Acceleration due to gravitation

If we replace the values to find the gravitational acceleration we have then,

1.7m = 0+\frac{1}{2} g*0.36^2

g= 26.2346m/s^2

Recall that the force of gravity on the planet Jupiter is 24.79 m / s² so the measure is closer to this planet. It is likely that you are in Jupiter.
