Explanation:

Answer:

Energy exists in different forms, all of which can be classified as either potential energy or kinetic energy. Potential energy is energy stored in an object due to its position or arrangement. Kinetic energy is energy of an object due to its movement - its motion.

so it would be the other way around

Explanation:

Answer:

As an object falls it gains kinetic energy whilst losing potential energy.

Answer:

Force

Explanation:

The mass of an object is the quantity of matter it contains. It is measured in kilograms.

Acceleration is the ratio of the change in the velocity of an object to the change in time. It is measured in m/[tex]s^{2}[/tex].

When the mass of an object is multiplied with its acceleration, this gives the average force applied on the object. As force is defined as agent that can change the state of an object.

i.e     F = m × a

where F is the force, m is the mass of the object and a its acceleration.

The two major classes of force are; contact force and field force.

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 .

Answer:

4.2

Explanation:

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:

I'm confused did you not get an answer at all

Answer:

There are 2 hydrogen atoms for every oxygen atom. The hydrogen will take up more space and is pushing the water lower in the test tube.

Explanation:

To find out what water is made of, we may have to look at its chemical formula, which is H2O. This basically tells us that the water molecule is composed of two elements: hydrogen and oxygen or, more precisely, two hydrogen atoms (H2) and one oxygen atom (O). Hydrogen and oxygen are gases at room temperature. Splitting water into its two components is much easier to do by a process called water electrolysis. Making hydrogen or oxygen this way seems simple. In water electrolysis, the source of energy used is electricity. An easy way to generate electricity is with a battery. Because pure water is not good at conducting electricity, however, electrolysis requires the addition of an electrolyte, such as salt or acid. The electrolyte dissolves in water and separates into ions (electrically charged particles) that move through the solutions and are able to conduct electricity this way.

As electrolysis progresses, the water level at the negative terminal becomes about half that of the positive terminal, meaning that we have collected double the amount of hydrogen gas compared with oxygen. The difference is due to the fact that one water molecule has two hydrogen atoms to one oxygen atom, as explained above. This means it takes two water molecules (2 H2O) to make one oxygen molecule (O2). At the same time, however, two molecules of water (2 H2O) can make two molecules of hydrogen (2 H2). Hence the answer.

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:

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:

U=3⋅30=90J

If the displacement is increasing as a function of time, then velocity is positive.

Since, V=d/t

so, Velocity is directly proportional to time.

Answer:

B

Explanation:

Answer:

hey friend, you haven't mentioned the statements...

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: B. 44.64 g

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

Mass of reactants = mass of iron + mass of oxygen = mass of iron + 34.7 g

Mass of product = mass of iron oxide = 79.34 g

As Mass of reactants = Mass of product

mass of iron + 34.7 g = 79.34 g

mass of iron = 44.64 g

Thus 44.64 g of iron was used in the reaction
