which produces the greater change in kinetic energy (assume that all of the work goes into kinetic energy)? group of answer choices . exerting a 10 n horizontal force through a distance of 5 m exerting a horizontal force of 40 n through a distance of 1m exerting a horizontal force of 20 n through a distance of 2 m exerting a 30 n horizontal force through a distance of 1.5 m

Answers

Answer 1

Since we know that kinetic energy equals work done, kinetic energy will produce more in the first scenario.Because the first case's work was more than the second, kinetic energy exists.

Does kinetic energy vary as a result of work?

According to the work-energy theorem, the net work performed by forces acting on an item equals the change in kinetic energy.

When does kinetic energy become more significant?

The kinetic energy of an object, in contrast to potential energy, is relative to other fixed and moving things that are present in its immediate vicinity. For instance, if the object is positioned at a higher height, its kinetic energy will be higher

Calculate the energy of a single photon at the transmitted frequency.


A)3.55 × 10-28 J/photon

B)3.55 × 10-31 J/photon

C)6.63 × 10-30 J/photon

Answers

Answer: A

Explanation: E=hv, E-energy, h-Planck constant, v-frequency
E=6.63×10^(-34)*535*10^3=3.55*10^(-28) (J) Photon energydoesn't depend on the power of radio station

The energy of a single photon at the transmitted frequency is

A)3.55 × 10^(-28)J/photon

What is the energy of a single photon?

Energy of photon can be rewritten as

E=hv,

Where, h is planck's constant  

λ is the wavelength of photon  

Where f is the frequency of photon  

Thus, the energy of a single photon at the transmitted frequency obtained by using the formula, Energy (E) is equal to Planck's constant (h) times the frequency.

E=6.63×10^(-34)× 535×10^3

E =3.55 × 10^(-28) (J)

A young boy swings a yo-yo horizontally above his head so that the yo-yo has a centripetal acceleration of 200 m/s^2. If the yo-up’s string is 0.33 m long, what is the yo-up’s tangential speed?

Answers

Answer:

v = 8.12 m/s

Explanation:

The centripetal acceleration of the yo-yo is given by the following formula:

[tex]a_c = \frac{v^2}{r}\\\\v^2 = a_cr\\v = \sqrt{a_cr}[/tex]

where,

v = tangential speed = ?

ac = centripetal acceleration = 200 m/s²

r = radius = length of string = 0.33 m

Therefore, using the given values in the formula, we get:

[tex]v = \sqrt{(200\ m/^2)(0.33\ m)}[/tex]

v = 8.12 m/s

Answers

Answer:

c) It gets positively charged

Explanation:

If an electrically neutral body is loaded with protons so it gets positively charged because proton has positive charge. When the protons is added to the neutral body, it can't remain neutral because the quantity of positive charges increases in the nucleus and it gets positively charged while on the other hand, the atom from which protons are taken will acquire negative charge due to presence of more number of electrons and we know that electrons has negative charge.

22. The energy of an electromagnetic wave and it's frequency are related by the following equation:

E = hf

Where:

E => is the energy

h => is the Planck's constant

f => is the frequency

From the equation i.e E = hf, we can conclude that the energy of a wave is directly proportional to it's frequency. This implies that an increase in the frequency of the wave will lead to an increase in the energy of the wave and also, a decrease in the frequency will lead to a decrease in the energy of the wave.

23. Gamma ray and radio wave are both electromagnetic waves. All electromagnetic waves has a constant speed of 3×10⁸ m/s in space.

Thus, gamma ray and radio wave have the same speed in space.
