What is the first law of thermodynamics?

• Energy can be destroyed but not created.

• Energy can be created but not destroyed.

• Energy cannot be created or destroyed, only transferred or transformed.

• Energy can be both created and destroyed.

What is the second law of thermodynamics?

• The total entropy of an isolated system always increases over time or remains constant in ideal cases.

• The total entropy of an isolated system is not affected by time.

• The total entropy of an isolated system remains constant over time.

• The total entropy of an isolated system always decreases over time.

What is the third law of thermodynamics?

• As the temperature approaches absolute zero, the entropy of a system approaches a minimum value.

• The third law of thermodynamics is also known as the law of conservation of energy.

• The third law of thermodynamics states that energy cannot be created or destroyed.

• Entropy of a system increases with temperature.

What is the formula for calculating electric field?

• E = F + q

• E = F - q

• E = F/q

• E = F * q

What is Faraday's law of electromagnetic induction?

• A change in electric field induces a magnetic force in a closed loop of wire.

• Faraday's law states that the induced electromotive force is directly proportional to the rate of change of magnetic field.

• Faraday's law only applies to conductors made of copper.

• A change in magnetic field induces an electromotive force in a closed loop of wire.

What is the equation for calculating the energy of a photon?

• E = h/c

• E = hf

• The theory of relativity describes the relationship between space and time.

• The theory of relativity is a concept that explains the relationship between mass and energy.

• The theory of relativity is a mathematical equation that explains the behavior of light.

• The theory of relativity is a hypothesis that states that time is not constant.

What is the equation for calculating time dilation?

• Δt' = Δt * √(1 - (v^2 / c^2))

• Δt' = Δt / √(1 - (v^2 / c^2))

• Δt' = Δt / (1 - (v^2 / c^2))

• Δt' = Δt * (1 - (v^2 / c^2))

What is the Heisenberg uncertainty principle?

• It is impossible to simultaneously know the exact position and momentum of a particle with absolute certainty.

• The Heisenberg uncertainty principle states that the position and momentum of a particle can be precisely determined at any given time.

• The Heisenberg uncertainty principle is a law that describes the relationship between energy and time.

• The Heisenberg uncertainty principle states that particles can exist in multiple states at the same time.
