Heat

Explanation:

Because chemical energy is stored, it is a form of potential energy. When a chemical reaction takes place, the stored chemical energy is released. Heat is often produced as a by-product of a chemical reaction – this is called an exothermic reaction.

Hope this helped.

Explanation:

Answer Should be B.

Its in Form of Heat.

The force of gravity between two masses increases as they are moved closer together.

option D.

Newton's law of universal gravitation states that the magnitude of the force between two masses is directly proportional to the product of the two masses and inversely proportional to the square of the distance between them.

F = GM²/R²

where;

The force of gravity between two masses increases as they are moved closer together. This is because gravity is an attractive force that depends on the distance between the masses.

Answer:

RT = 54 Ohms

Explanation:

Given the following data;

Resistance = 18 Ohms

Voltage = 12 Volts

To find the equivalent resistance (RT) of the circuit;

For a series connection, the formula is;

RT = R1 + R2 + R3

RT = 18 + 18 + 18

RT = 54 Ohms

Or

RT = 3*R

RT = 3 * 18

RT = 54 Ohms

Answer:

Star, hydrogen and energy

Explanation:

A star is a large ball of gas that generates its own energy by fusing hydrogen atoms to make helium. It is held together by its own gravity. This process emits a tremendous amount of energy, and some of the energy is in the form of light.

The energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. When the core is hot enough, nuclear fusion commences. Fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.

Actually Welcome to the concept of Net force on a body.

We know that net force on a body is the force that is calculated from all direction and added , if there is any force remained at last, then the forces are unbalanced,

and if the net force on a body is Zero, then it is a balanced force,

here,

Force to left on skier = 50 N

Force to right on skier = 40 N

hence the net force = left force - right force

Net force = 50 - 40 ==> 10 N

hence the Net force is 10 N in the left direction of the skier.

Answer:

W = 0 J

Explanation:

The amount of work done by gas at constant pressure is given by the following formula:

[tex]W = P\Delta V[/tex]

where,

W = Work done by the gas

P = Pressure of the gas

ΔV = Change in the volume of the gas

Since the volume of the gas is constant. Therefore, there is no change in the volume of the gas:

[tex]W = P(0\ m^3)\\[/tex]

W = 0 J

Answer:

418.18 feet

Explanation:

Applying,

v = d/t.................. Equation 1

Where v = velocity, d = distance, t = time.

make d the subeject of the equation

d = vt............ Equation 2

From the question,

Given: v = 57.4 mi/h, t = 4.96 s = (4.96/3600) h = 1.38×10⁻³ h

Substitute these values into equation 2

d = (57.4×1.38×10⁻³)

d = 0.0792 mi

Converting from miles to feet

d = (0.0792×5280) feet

d = 418.18 feet

Answer:

720 Joules

Explanation:

Given: 60 W light bulb powered by 620,000 J of energy. 20 percent efficient in converting electrical energy into light energy

To find: how many joules of light energy does this light bulb produce each time?

Formula: [tex]E = \frac{hc}{A}[/tex]

Solution: The total amount of energy generated by the light bulb every minute is 3600 Joules. If the light bulb is only twenty (20) percent efficient in converting that energy to visible light energy, that would be twenty percent of the total.

E (Joules) = P (Watts)  X  t (seconds)

E = 60 W  X  60 seconds

E = 3600 Joules of energy

20% of 3600 = 720 Joules

Therefore, it produces 720 joules of light each time.
