What is law of conservation of energy ?

Law of conservation of energy is the principle of physics according to which the energy of interacting bodies or particles in a closed system remains constant.

Total energy of any system always remains constant . Also from law of conservation of energy it can be stated as energy can neither be created nor be destroyed ,it only transforms form one form to other form .

hence , option 1) : The total amount of energy in the universe remains constant.

4) Energy can be converted from one form to another.

5) Energy cannot be created or destroyed.

A roller coaster with a potential energy of 235,200 J sits at the top of a 30 m high hill. What is the mass of the roller coaster? (Formula: PE = mgh)

Answers

A roller coaster with a potential energy of 235,200 J and sits at the top of a 30 m high hill has a mass equivalent to 799.18 kg. Using the formula of PE = mgh, all of the values are already known, so direct substitution can be used. PE is the potential energy, m is the mass, g is gravitational constant (9.81 m/s2), and h is the height.

Answer: its 800 kg thank me later ;)

What is the current when the resistance is 5 ohms and the voltage is 10 volts?A. 10 – 5 = 5 amps

B. 10 ÷ 5 = 2 amps

C. 10 × 5 = 50 amps

D. 10 + 5 = 15 amps

Answers

Ohm's Law states V = IR
So,
I = V/R
The answer is B. 10/5=2 amps

The ability of solid rock to flow is called _____. convection plasticity seafloor spreading seismology

Answers

The ability of solid rock to flow is called Plasticity.

Plasticity is the deformation of a solid mateial which resulted in non reversible changes of shape in response to applied force.

Another example of plasticity is when you bend metal through a forcer force to create an art or kitchen set

Answer:

The ability of solid rock to flow is called Plasticity.

Explanation:

Plasticity is the deformation of a solid material which resulted in non reversible changes of shape in response to applied force.

Critical thinking!!Comparing and Contrasting You carry
two heavy bags of groceries upstairs to your
kitchen. Will you do more work on the bags if
you carry them up one at a time? Explain.

Answers

Answer:

no both remains same...

Explanation:

because the work done is given by the product of the both the masses added (m+m) Displacement

and second time when you carry the bags individually it comes out to be the same m×displacement + m×displacement

State two factors which affect moment of force

Answers

Two factors that affect the moment of force are the magnitude of the force applied and the distance from the axis of rotation at which the force is applied.
