A light bulb used in homes converts electrical energy into light energy  The amount of light energy output by the lamp in 9.0 hours of use is 23.4 J.

The ability of an atom's charged particles to initiate an activity or move an object is known as electrical energy.

The proportion of the device's useful energy transferred to the device's total energy input.

The input power of the light bulb = 52 w.

In 9.0 hours of use.

Hence,

52 x 9.0 = 468 J

The following equation calculates efficiency as a percentage and is represented as follows:

Efficiency is calculated as (Usable Energy Output/Total Energy Input) x 100%.

The lightbulb's efficiency is 5.0%.

(The light energy output/ 468) x 100% = 5%

So, the light energy output = 23.4 J

Therefore, the amount of light energy output by the lamp in 9.0 hours of use is 23.4 J.

Answer:

250mn

Explanation:

Answer:

-0.75 m

Explanation:

The displacement of the girl is given by x = x₀cosωt where x₀ = maximum displacement of swing = 1.5 m, ω = angular frequency = π/3 rad/s and t = time of swing = 4 s

Substituting the values of the variables into the equation, we have

x = x₀cosωt

x = (1.5 m)cos(π/3 rad/s × 4 s)

x = (1.5 m)cos(2π/3)

x = (1.5 m)cos120°

x = 1.5 m × -0.5

x = -0.75 m

So, the girl is 0.75 m to the left of the equilibrium position 4 seconds into the motion.

Answer:

The ball and the wall experience the same force.

Explanation:

According to the third law of Newton, which states that "for every action, there is an equal and opposite reaction", this means that when an object 1 acts on object 2 with a certain force, object 2 also acts on object 1 with the same magnitude of force but in an opposite direction.

According to this question, a ball hits a wall with a certain force. This means that the wall will react on the ball with the same force magnitude, but in an opposite manner. Hence, the ball and the wall experience the same force.

Answer:

Frequency

Explanation:

A period is the number of revolutions in a minute.

[tex] Period = \frac {time}{number \; of \; oscillations}[/tex]

Also, frequency can be defined as number of oscillation per unit time.

Mathematically, frequency is given by the formula;

[tex] Frequency = \frac {number \; of \; oscillations}{time}[/tex]

Thus, we can deduce that frequency of an oscillation is the inverse of the period (time) of oscillation.

Mathematically, period is expressed as;

[tex] Period = \frac {1}{frequency}[/tex]

This ultimately implies that, an object's period of oscillation can always be used to solve for frequency.

Answer:

A is the correct answer 0.158

158 Milligrams of salt are on the table there would be 0.158 grams of salt on the table, therefore the correct answer is option A.

A unit of measurement is a specified magnitude of a quantity that is established and used as a standard for measuring other quantities of the same kind. It is determined by convention or regulation.

As given in the problem 158 Milligrams of salt are on the table, then we have to find out how many grams of salt is on the table,

1000 milligrams = 1 gram

1 milligram = 1 / 1000 grams

158 milligram = 158 × 1 / 1000 grams

                      =0.158 grams

Thus, there would be 0.158 grams of salt on the table, the correct answer is option A.

Answer:

The pressure exerted by the girl is 245,000 N/m²

Explanation:

Given;

mass of the girl, m = 50 kg

area of the girl's shoe, A = 0.002 m²

The pressure exerted by the girl is calculated as follows;

[tex]P = \frac{F}{A} \\\\Where;\\F \ is \ the \ force \ exerted \ by \ girl's \ weight\\\\P = \frac{F}{A} = \frac{mg}{A} = \frac{50 \times 9.8}{0.002} = 245,000 \ N/m^2[/tex]

Therefore, the pressure exerted by the girl is 245,000 N/m²

Pressure will decrease whenever the surface area increases, and when the weight of the object is reduced.

[tex] \color{green} {\huge \circ \degree \degree} \boxed{\normalsize{ \mathrm{ \underline{ \color{red}pressure \: \: will \: \: decrease}}} } \: \: \huge \color{green}\degree \degree \circ[/tex]

We know that,

[tex]\large \boxed{ \mathrm{pressure = \frac{mass}{area \: \: of \: \: surface}} }[/tex]

Now, we can observe that the area of surface is inversely proportional to the pressure, Therefore pressure will change opposite to the change in surface area in contact.

So, if we increase the surface area then there would be decrease in magnitude of pressure.

The star is bigger than our sun. The correct option is 1.

The flow chart of the life cycle of a star indicates that the star starts as a nebula, which is a cloud of gas and dust. The nebula can collapse due to gravitational forces and form a protostar. The protostar can then continue to contract and heat up until it reaches a temperature and density at which nuclear fusion can occur, leading to the star entering the main sequence phase.

The size of a star is determined by its mass, and the more massive a star is, the bigger it will be. Based on this information, we can infer that if a star follows the life cycle shown in the flow chart, starting from a nebula and eventually reaching the main sequence, it must be at least as massive as our sun or even more massive, since only stars with sufficient mass can become main sequence stars.

the power output P = 1484 W

Explanation:

Power P  = Force× speed

Given that motor of a battery-powered scooter can maintain a speed of 5.3 m/s by providing a force of 280 N.

Therefore,the power output of the motor P = 280×5.3 = 1484 W

Hence, the power output P = 1484 W

Answer:

R = 25 Ohms

Explanation:

Given the following data;

Voltage (p.d) = 15 V

Current = 0.6 A

To find the resistance of the wire;

Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.

Mathematically, Ohm's law is given by the formula;

[tex] V = IR[/tex]

Where;

V represents voltage measured in voltage.

I represents current measured in amperes.

R represents resistance measured in ohms.

[tex] R = \frac {V}{I} [/tex]

Substituting into the equation, we have;

[tex] R = \frac {15}{0.6} [/tex]

R = 25 Ohms

the Moon passes between Earth and the Sun Even though the Moon is much smaller than the Sun, because it is just the right distance away from Earth, the Moon can fully block the Sun's light from Earth's perspective This completely blocks out the Sun's light

Answer:

It's all about perspective. The moon is far closer to the Earth than the Sun is, so they appear roughly the same size. If they were closer to each other, then obviously the moon wouldn't be large enough to cover a substantial amount of the sun's light. But given the huge distance both between them and the moon and the earth, to us they look relatively the same.
