What direction does energy transfer to the direction of a light wave

Answer:

4 x 10⁶m/s²

Explanation:

Given parameters:

Initial velocity  = 0m/s

Time  = 0.0001s

Final velocity  = 400m/s

Unknown:

Acceleration of the object  = ?

Solution:

Acceleration is the rate of change of velocity with time;

 Acceleration  = [tex]\frac{Final velocity - Initial velocity }{Time }[/tex]  

 Acceleration  = [tex]\frac{400 - 0}{0.0001}[/tex]   = 4 x 10⁶m/s²

Answer:

Explanation:

Take for example you place two eggs in the water. One starts to sink and one remains floating. They have the same volume but the one that sinks is cracked just a little, which as soon as it hits the water, water starts to go in the egg. Then that changes the volume of the egg. (I've done this expirement before) It can also be the way you place the object in the water, or one object has been in the water longer. The buoyancy can be the way they are positioned/placed in the water. One may be more absorbant to the water as well.

I hope you understand what I am trying to say.

Answer: Gamma rays (violet) have the shortest wavelengths and the highest frequencies.

Explanation: The wavelength of the gamma rays is less than 0.01 nanometers. The frequency of a wave is inversely proportional to its wavelength. That means that waves with a high frequency have a short wavelength, while waves with a low frequency have a longer wavelength.

The electromagnetic waves have the shortest wavelength and the highest frequency is Gamma rays (violet).

Gamma radiation, from gamma rays (γ), is a type of electromagnetic radiation usually produced by radioactive elements. Gamma rays, due to their high energy, are able to penetrate matter more deeply than alpha or beta radiation.

Gamma ray is a type of high frequency electromagnetic radiation usually produced by radioactive elements.

Answer:

The internal energy of a substance is equal to the total amount of potential energy and kinetic energy of ALL the particles in the substance.

For example, when the temperature increases (more temperature means more energy), the kinetic energy of the particles in the substance increases.

And when we reach a point near a change of phase (like near fusion point) there is energy used to break the bonds between the particles, then we have an increase in potential energy.

Then we could write the internal energy as:

U = ∑(KEₙ) + ∑(PEₙ)

Where ∑(KEₙ) and ∑(PEₙ) are the sums of the kinetic energy and potential energy of all the particles in the substance.

The equation that best summarizes the internal energy (U) of a substance that has both kinetic and potential energy is U = ∑(KEₙ) + ∑(PEₙ).

Therefore, equation that best summarizes the internal energy (U) of a substance that has both kinetic and potential energy is U = ∑(KEₙ) + ∑(PEₙ).

Answer:

The answer is long- term goal

Explanation:

Answer:

h = 3.3 m (Look at the explanation below, please)

Explanation:

This question has to do with kinetic and potential energy. At the beginning (time of launch), there is no potential energy- we assume it starts from the ground. There, is, however, kinetic energy

Kinetic energy = [tex]\frac{1}{2}[/tex]m[tex]v^{2}[/tex]

Plug in the numbers = [tex]\frac{1}{2}[/tex](4.0)([tex]8^{2}[/tex])

Solve = 2(64) = 128 J

Now, since we know that the mechanical energy of a system always remains constant in the absence of outside forces (there is no outside force here), we can deduce that the kinetic energy at the bottom is equal to the potential energy at the top. Look at the diagram I have attached.

Potential energy = mgh = (4.0)(9.8)(h) = 39.2(h)

Kinetic energy = Potential Energy

128 J = 39.2h

h = 3.26 m

h= 3.3 m (because of significant figures)

Answer:

d = 1.65 m

Explanation:

Given that,

The speed of a ball, v = 3 m/s

A ball rolls a level table that is 1.5 m above the floor.

We can find how long the ball is in free fall. We can use the second equation of kinematics as follows :

[tex]s=ut+\dfrac{1}{2}gt^2[/tex]

u is the initial speed in the vertical direction

So,

[tex]s=\dfrac{1}{2}gt^2\\\\t=\sqrt{\dfrac{2s}{g}} \\\\t=\sqrt{\dfrac{2\times 1.5}{9.8}} \\\\t=0.55\ s[/tex]

Now, using the formula of velocity.

[tex]v=\dfrac{d}{t}\\\\d=vt\\\\d=3\times 0.55\\\\d=1.65\ m[/tex]

So, the landing spot is at 1.65 m from the table.

Answer:

Height of wall (Perpendicular) = 11.31 ft (Approx)

Explanation:

Given:

Base Distance (Base) = 4 feet

Height of ladder (Hypotenuse) = 12 feet

Find:

Height of wall (Perpendicular)

Computation:

Perpendicular = √Hypotenuse² - Base²

Height of wall (Perpendicular) = √12² - 4²

Height of wall (Perpendicular) = √144 - 16

Height of wall (Perpendicular) = √128

Height of wall (Perpendicular) = 11.31 ft (Approx)

Answer:

Final velocity v = 4 m/s

Explanation:

Given:

Initial velocity u = 0 m/s

Acceleration a = 0.16 m/s²

Distance s = 50 m

Find:

Final velocity v

Computation:

Using; v² = u² + 2as

v² = (0)² + 2(0.16)(50)

v² = 16 m/s

v = 4 m/s

Final velocity v = 4 m/s

Answer:

If I’m correct 300 joules

Explanation:

Answer:

4.5m

Explanation:

Distance is the total length of path traveled or covered by a body.

So distance is a scalar quantity, it only has magnitude but no direction.

Therefore:

Total distance = 3 m + [tex]\frac{1}{2}[/tex](3)

So;

        3 + 1.5  = 4.5m

Total distance covered 4.5m by the body.

The chemical process which requires energy is breaking bond in KOH and HBr. Hence, option C is correct.

The capacity to perform work is known as energy in physics. Potential, kinematic, thermodynamic, electromagnetic, chemical, nuclear, and other types are all possible.

As energy is transferred through one body to another, there is also heat and work. As a result, heat transfer may result in thermal energy, whereas labor done may result in mechanical power.

As per the given reaction in the question,

KOH + HBr - KBr + H20

Here, in this reaction the chemical process which requires the energy is at the time of breaking of bonds in KOH and HBr at that time the energy is required.

Therefore, it is concluded that breaking bonds in KOH and HBr i.e., option C is correct.

Earth's rotation and spherical shape cause winds to veer to the right (in the northern Hemisphere) or to the left (in the southern Hemisphere) of the direction they want to go.  This is known as the Coriolis effect.

If you didn't know that you're on a rotating Earth, and you looked at the patterns of the winds, you'd think there's some kind of force that's making the airflow veer to the right or left of the direction it actually wants to go.  This is known as the Coriolis force.  It's a"pseudo force", because it doesn't really exist.  It only LOOKS like it's there, because of the Earth's rotation and spherical shape..

The statement "Earth's rotation causes winds to veer to the west or to the east" is true about the Coriolis effect.

Fluid materials such as wind and ocean currents take different directions depending on the hemisphere, this movement of deviation is called the Coriolis effect.

Therefore, we can conclude that the force that tends to deflect the trajectory of objects moving across the entire earth's surface is known as the Coriolis effect.
