what is photoelectric effect​

Answers

[tex]{\underbrace{\sf{PHOTO-ELECTRIC~EFFECT }}}[/tex]

The photoelectric effect is a phenomenon in which electrons are ejected from the surface of a metal when light is incident on it. These ejected electrons are called photoelectrons. It is important to note that the emission of photoelectrons and the kinetic energy of the ejected photoelectrons is dependent on the frequency of the light that is incident on the metal’s surface.

Answer:

Photoelectric effect is the phenomenon in which electrically charged particles are released from or within a material when it absorbs electromagnetic radiation. The effect is often defined as the ejection of electrons from a metal plate when light falls on it.

A car has a mass of 1000 kg and is travelling at a speed of 26 m/s. Calculate the kinetic energy of the
car. Use the word equation below to help you.
kinetic energy = 0.5 x mass x (speed)?

Answers

Answer:

338,000 J

Explanation:

The kinetic energy of an object can be found by using the formula

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

m is the mass

v is the velocity

From the question we have

[tex]k = \frac{1}{2} \times 1000 \times {26}^{2} \\ = 500 \times 676 \\ = 338000[/tex]

We have the final answer as

338,000 J

2.) Explain why the starting angle doesnt impact the time it takes the pendulum to swing back and forth?​

Answers

The starting angle θθ of a pendulum does not affect its period for θ<<1θ<<1. At higher angles, however, the period TT increases with increasing θθ.

The relation between TT and θθ can be derived by solving the equation of motion of the simple pendulum (from F=ma)

−gsinθ=lθ¨−gain⁡θ=lθ¨

For small angles, θ≪1,θ≪1, and hence sinθ≈θsin⁡θ≈θ. Hence,

θ¨=−glθθ¨=−glθ

This second-order differential equation can be solved to get θ=θ0cos(ωt),ω=gl−−√θ=θ0cos⁡(ωt),ω=gl. The period is thus T=2πω=2πlg−−√T=2πω=2πlg, which is independent of the starting angle θ0θ0.

For large angles, however, the above derivation is invalid. Without going into the derivation, the general expression of the period is T=2πlg−−√(1+θ2016+...)T=2πlg(1+θ0216+...). At large angles, the θ2016θ0216 term starts to grow big and cause

Answer:

16.7s

2x10^1 s (if you need a 1 significant digit answer)

Explanation:

The formula for average velocity is

Vavg = Δd/Δt

Fill in the known values

6m/s = 100m/Δt

Rearrange the equation

Δt = 100m/6m/s

Δt = 16.7s

A lamp is labelled '230 V, 100 W'. How many joules of electrical energy is changed to thermal energy and light if the lamp is switched on for 2 hours?

Answers

Given;

V = 230V

Power, P = 100W

time, t = 2hrs = 7200s

from,

P = IV

and Energy, E= Pt

E = 100*7200

E = 720000 Joules

E = 720KJ

Answer:

Formula  E(J) = P(W) × t(s)

3600 Seconds in an hour

7200 seconds in two hours.

watts = 100

100 x 7200 = 720000

Explanation:

Watts to joules calculation

The energy E in joules (J) is equal to the power P in watts (W), times the time period t in seconds (s):

E(J) = P(W) × t(s)

Energy cannot be created or destroyed, only converted from one form to another. These conversions can be shown in Sankey diagrams. Efficiency is a measure of how much useful energy is converted. Attachment 1

Modern energy-saving lamps and LEDs (light-emitting diodes) work in a different way. They transfer a greater proportion of electrical energy as light energy. Attachment 2

From the diagram, you can see that much less electrical energy is transferred, or 'wasted', as heat energy from the energy-saving lamp. It's more efficient than the filament lamp.

Calculating efficiency

The efficiency of a device, such as a lamp, can be calculated:

efficiency = useful energy out ÷ total energy in (for a decimal efficiency)

or

efficiency = (useful energy out ÷ total energy in) × 100 (for a percentage efficiency)

The efficiency of the filament lamp is 10 ÷ 100 = 0.10 (or 10%). This means that 10 per cent of the electrical energy supplied is transferred as light energy (90 per cent is transferred as heat energy).

The efficiency of the energy-saving lamp is 75 ÷ 100 = 0.75 (or 75 per cent). This means that 75 per cent of the electrical energy supplied is transferred as light energy (25 per cent is transferred as heat energy).

Note that the efficiency of a device will always be less than 100 per cent. Occasionally the power is shown in W instead of the energy in J. The equations are the same – just substitute power for energy:

efficiency = useful power out ÷ total power in (for a decimal efficiency)

or

efficiency = (useful power out ÷ total power in) × 100 (for a percentage efficiency)

This is the Sankey diagram for a typical energy-saving lamp:

They have just learned that the ship's crew is planning mutiny against the captain and officers. Clayton had recently intervened to prevent the captain from harming a crew member, Black Michael. "Deuced cheerful outlook, Alice," said Clayton. "You should warn the captain at once, John. Possibly the trouble may yet be averted," she said. "I suppose I should, but yet from purely selfish motives I am almost prompted to 'keep a still tongue in my 'ead.' Whatever they do now they will spare us in recognition of my stand for this fellow Black Michael, but should they find that I had betrayed them there would be no mercy shown us, Alice." "You have but one duty, John, and that lies in the interest of vested authority. If you do not warn the captain you are as much a party to whatever follows as though you had helped to plot and carry it out with your own head and hands." "You do not understand, dear," replied Clayton. "It is of you I am thinkingthere lies my first duty. The captain has brought this condition upon himself, so why then should I risk subjecting my wife to unthinkable horrors in a probably futile attempt to save him from his own brutal folly? You have no conception, dear, of what would follow were this pack of cutthroats to gain control of the Fuwalda." "Duty is duty, John, and no amount of sophistries may change it. I would be a poor wife for an English lord were I to be responsible for his shirking a plain duty. I realize the danger which must follow, but I can face it with you." "Have it as you will then, Alice," he answered, smiling. "Maybe we are borrowing trouble. While I do not like the looks of things on board this ship, they may not be so bad after all, for it is possible that the 'Ancient Mariner' was but voicing the desires of his wicked old heart rather than speaking of real facts.
