Explain why the law of conservation of energy can mean that we do not have unlimited sources of energy.
oee [108]
<span>The law of conservation of energy states that energy can neither be created nor destroyed - it can only be converted from one form to another. It basically means that energy can't just appear, but has to be converted from existing energy; for example, the chemical energy in petrol is turned into electrical energy to power a car.Remember the total energy of universe is constant,,and no more energy can be drawn from out if we collect all universe's energy at a single point(its the big bang energy splitted during </span>

Marat540 [252]

Answer:

c.The atoms in the solid would be vibrating in position.

Explanation:

The properties of solid, liquid and gas which makes them different ares the intermolecular interactions between particles and the thermal energy.

Solids molecules are fixed in their position and may show vibrations.

Liquid molecules can move slowly as they have inter-molecular forces in between solid and gas,

Gas molecules can move vigorously here and there due very weak inter-molecular interactions and high thermal energy.

Thus the answer would be the atoms in the solid would be vibrating in position.

Tom pushes on a 50-kilogram box with a force of 25 newtons. Assuming the surface on which the box moves is frictionless, at what
zhannawk [14.2K]

Assuming the surface on which the box moves is frictionless, the rate at which the box accelerate is equal to 0.5 m/s^2.

<u>Given the following data:</u>

  • Mass of box = 50 kilogram
  • Force = 25 newtons.

To determine the rate at which the box accelerate, assuming the surface on which the box moves is frictionless:

Mathematically, Newton's Second Law of Motion is given by the formula;

Force = mass \times acceleration

Making acceleration the subject of formula, we have:

Acceleration =\frac{Force}{mass}

Substituting the given parameters into the formula, we have;

Acceleration = \frac{25}{50}

Acceleration = 0.5 m/s^2

Answer:

Increase the concentration of the solution

Explanation:

Increasing the solute would increase the concentration. Increasing the solvent would decrease the concentration. For instance, if your lemonade was too tart, you would add more water to decrease the concentration
