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.

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

Explanation:

Answer:

B

Explanation:

It is true that a neutral atom has the same number of electrons as it does neutrons.

The neutrons are neutral particles, whereas the electrons are negatively charged particles.

Instead of neutrons, a neutral atom has an equal number of protons and electrons. Because they have no charge, neutrons are electrically neutral particles. The negative charge of the electrons in the electron shells encircling the nucleus in a neutral atom balances the positive charge of the protons in the nucleus. In a neutral atom, the number of protons and electrons is therefore identical, but the number of neutrons is variable.

Hence, It is true that a neutral atom has the same number of electrons as it does neutrons.

Answer:

10.9 m/s, −1.82 m/s

Explanation:

We have,

Anand gets into an elevator and travels 50 m straight up in a time of 5 s. He then travels in the opposite direction, straight down, for 70 m in a time of 6 s.

Total time of journey is 11 seconds.

Total distance is 50 m + 70 m = 120 m

Total displacement is 50 m - 70 m = -20 m

Average speed, [tex]s=\dfrac{120\ m}{11\ s}=10.9\ m/s[/tex]

Average velocity, [tex]v=\dfrac{-20\ m}{11\ s}=-1.82 \ m/s[/tex]

So, the correct option is (b) 10.9 m/s, −1.82 m/s.

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.

Force, [tex]F=2.88\times 10^{-3}\ N[/tex]

Explanation:

Charge 1, [tex]q_1=1\times 10^{-7}\ C[/tex]

Charge 2, [tex]q_2=-2\times 10^{-7}\ C[/tex]

Distance between charges, d = 0.25 m

It is required to find the force between charges. The charges are opposite the force between them is attractive. The force between charges is given by :

[tex]F=\dfrac{kq_1q_2}{d^2}\\\\F=\dfrac{9\times 10^9\times 1\times 10^{-7}\times 2\times 10^{-7}}{(0.25)^2}\\\\F=2.88\times 10^{-3}\ N[/tex]

So, the force between charges is [tex]2.88\times 10^{-3}\ N[/tex].

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.

Answer:

Gravitation.

Explanation:

The space where the planets are is absolutely empty, so there is no friction. The planets may have some magnetism, but magnetic forces are negligible when compared to the Gravitational force over the planets due to the Sun mass. The equation which describes the Sun's force is: F =  [tex]\frac{G.msun.mplanet}{r^{2} }[/tex] which is the famous Newton's gravitational law. Radiation from other stars doesn't contribute to the planets' motion, which is elliptical trajectory.
