Answer: Option B: As the temperature increases, the kinetic energy of the particles increases.

Explanation: The temperature is a manifestation of energy.

This means that if a given object is increasing its temperature, then the energy of the object is also increasing. And one of the where the energy increases is by an increment in the kinetic energy of the particles in the object.

Then, if the temperature of an object increases, the kinetic energy of the particles also increases.

Answer:

As the temperature increases, the kinetic energy of the particles increases.

Explanation:

When the temperature of the substance increases, the velocity increases which makes the movement of the particles to speed up. This causes the particles to increase. Therefore, as the temperature increases, the kinetic energy of the particles also increases.

What is the maximum velocity (in m/s) of electrons ejected from a material by 85 nm photons, if they are bound to the material b

diamong [38]

The maximum velocity of electrons is v = 3.20 × 10¹⁵ m/s

The wavelength of photons λ = 85 nm

W = 4.66 ev

<h3>What is photoelectric effect and how velocity of photoelectrons is calculated?</h3>

The emission of electrons happened and absorbed through the electromagnetic radiation is said to be photoelectric effect.

Photoelectric cells, photodiodes works on the principle of photoelectric effect.

According to of photoelectric effect,

E = hν

Here, hc / λ = W + KE max

hc / λ = W + 1/2 mv² max

v² = sqrt of (( hc / λ - W) (2/m))

I cap denotes λ ,

substituting all the values,

v = sqrt of ( (6.623 × 10⁻³⁴ Js ) ( 3 × 10⁸ m/s) / (85 nm) - 4.66ev) (2/ 9.1× 10⁻³¹

v = sqrt of ((1.987800 × 10⁻²⁵ / 85 × 10 ⁹ ) - 4.66 ev ) ( 2.197 × 10³⁰)

v = sqrt of ((2.338588 × 10⁻³⁶) - 4.66 ev ) ( 2.197 × 10³⁰)3.2

v = 3.20 × 10¹⁵ m/s

Thus, the maximum velocity is calculated as v = 3.20 × 10¹⁵ m/s.

mechanical equivalent of heat Do the data for the second part of the experiment support or refute the second hypothesis

Ksivusya [100]

The data for the first part of the experiment support the first hypothesis.
As the force applied to the cart increased, the acceleration of the cart increased.
Since the increase in the applied force caused the increase in the cart's acceleration, force and acceleration are directly proportional to each other, which is in accordance with Newton's second law.

When we state something about the results on the basis whether the observed data supports the original hypothesis, we say that we are concluding the results.

What is the relationship between force and acceleration based on Newton's 2nd law?

Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

An earthquake in San Francisco produces a wave with a period of 0.80 seconds and a wavelength of 40 m., How long will it take fo

gtnhenbr [62]

Answer:

A) 3.11 Hrs

Explanation:

Wave speed is given by the formula

$Speed = \frac{wavelength}{Time\: period}$

now we will have

$speed = \frac{40}{0.80}$

$v = 50 m/s$

now the time taken by the wave to move the distance 560 km is given as

$t = \frac{distance}{speed}$

$t = \frac{560\times 10^3}{50}$

$t = 11200 s$

t = 3.11 hours

Which of these is a landform created due to erosion by glaciers? Delta Horn Sandbars Spit

Marina CMI [18]

Answer:

The answer is option B, horn.

Explanation:

The landform horn was formed because when glaciers erode down to form a sharp peak which is called a horn. All of the other options are false because none of those land forms are formed because of the erosion of glaciers
