Answer:

The water above receives energy as it falls down the short waterfall. This energy was stored as potential energy in the gravitational field of the Earth and came out of storage as the water dropped. This energy which came out of the gravitational field ended up being expressed as the kinetic energy of the water. That is, the water gains kinetic energy as it drops. An ounce of water is going faster when it hits the bottom of the waterfall than it was when it went over the top of the waterfall

Explanation:

The drops of water contain the most gravitational potential energy at the top before they start falling.

At the top of the waterfall

At the top of the waterfall, the water drops have the most gravitational potential energy before they start falling as the water at the peak of the waterfall is higher in the Earth's gravitational field and has gravitational potential energy. The potential energy is converted to kinetic energy when it falls. As a result, energy is not created; it was always there, stored as potential energy.

Potential energy is energy that is stored and is determined by the relative positions of various pieces of a system. Kinetic energy is the energy that an item or particle has as a result of its movement.

Answer:

Dinesh should put the fulcrum 2 m from himself and 7 m from the package.

Explanation:

Let the fulcrum be x meters from Dinesh's end.

The sum of clockwise moment must balance the sum of anti-clockwise moment.

Taking a moment about the fulcrum

(Force exerted by Dinesh) × (Distance of Dinesh from the fulcrum) = (Weight of the package) × (Distance of the package from the fulcrum)

Force exerted by Dinesh = 1127 N

Distance of Dinesh from the fulcrum = x m

Weight of the package = 322 N

Distance of the package from the fulcrum = (9 - x) m

1127 × x = 322 (9 - x)

1127x = 2,898 - 322x

1127x + 322x = 2,898

1449x = 2898

x = (2898/1449) = 2 m

Hence, Dinesh should put the fulcrum 2 m from himself and 7 m from the package.

The power of the light bulb is 15 watts.

Power in physics is defined as the rate of energy per unit time or in other words the work done by any electrical appliance per unit time. Power is expressed as -

P = E/T where E is Energy and T is the time period.

Given that the light bulb emits 30 J light energy in 2 seconds.

We have E = 30J and T = 2 seconds.

Therefore power(P) = Energy(E) / Time(T)

∴  P = 30 / 2 = 15 watts

Thus the power of the light bulb is 15 watts.

Answer:

Explanation:

current measures charge flowing per second .

A current of .867 A means charge of .867 coulomb is flowing per second

charge flowing per minute = .867 x 60

= 52.02 coulomb

one electrons carries a charge of 1.6 x 10⁻¹⁹ Coulomb

So no of charge flowing per minute

= 52.02 / 1.6 x 10⁻¹⁹

= 32.5 x 10¹⁹ .

The acceleration of the bag of sand is [tex]1\ m/s^2[/tex].

Explanation:

We have,

Mass of a bag of sand is 100 kg

Weight of the bag of sand is 100 N

It is required to find the acceleration of the bag when it is dropped. The weight of an object is given by :

[tex]F =ma[/tex]

When it is dropped, a = g

[tex]g=\dfrac{F}{m}\\\\g=\dfrac{100}{100}\\\\g=1\ m/s^2[/tex]

So, the acceleration of the bag of sand is [tex]1\ m/s^2[/tex].

The order of the surface temperature of the stars, starting from the highest to the lowest is Y > X > W > Z.

Wien's displacement law states that, the black-body radiation curve for different temperatures will have different peaks of wavelengths and the wavelength is inversely proportional to the surface temperature.

Here,

According to Wien's displacement law,

The wavelength of the star is inversely proportional to its surface temperature.

λ [tex]\alpha[/tex] 1/T

where T is the surface temperature.

Therefore, the star with lowest wavelength will have the highest surface temperature.

Consider the wavelengths of each stars given,

The increasing order of their wavelengths can be written as,

λ(Orange) > λ(Yellow) > λ(White) > λ(Blue)

Therefore the increasing order of their surface temperatures will be,

T(Blue) > T(White) > T(Yellow) > T(Orange)

Hence,

The order of the surface temperature of the stars, starting from the highest to the lowest is Y > X > W > Z.

Answer:

Potential energy

441 joules

Explanation:

The flower pot is not moving so it does not have kinetic energy. Anything that is still and a distance from the ground does have potential energy.

Amount of energy: p=mggh

p=1.5(9.8)(30)=441 joules

The flower pot's energy is measured in potential energy since it is remaining stationary and the energy is stored,  the flowerpot is not moving about so it is not kinetic energy.

The formula for potential energy is:

GPE = mgh

The m stands more mass, the g stands for gravitational energy (9.8m/s^2) and the h stands for height.

Our values for the following terms are:

M = 1.5kg

G = 9.8m/s^2

H = 30 meters

Now, we can plug it into our formula to solve for the amount of potential energy.

GPE = 1.5(9.8)(30)

First, let's multiply the gravitational energy and the height.

30 x 9.8 = 294

Then, multiply the mass by the result.

1.5 x 294 = 441

Therefore, the potential energy of the flowerpot is 441J.

Answer:

As the height is negative , image is inverted. This means it is inverted and real

Answer:

It is Potential and corresponding to

90

J

.

Explanation:

Potential Energy is energy stored in the system and ready (potentially) to be changed into, say, Kinetic Energy through movement.

The general expression for Gravitational Potential Energy is:

U=mgh

where:

mg is the weight; h is the height relative to a certain reference level (the ground in this case) choosen to have zero Potential Energy.

With your data we get:
