What is an example of a light mediem wave.

Answers

Answer 1
Answer: Speed of light is an example of a light medium wave.

Most famous Michelson-Morley (1887) demonstrated that light travels at the same speed regardless  of whether it was measured in the direction of the Earth's motion or at right angles to it. When the light travels through a vacuum: It moves from medium to medium (example: air to glass) speed can change depending of the new medium's index of refraction and the "bending" of light is essentially how lenses work.
Answer 2
Answer: Hey there

An example of a light medium wave is Speed of light.

Answers

the steamed milk and the boiling water would have more thermal energy.

Thermal energy is the total kinetic energy in an object.

In which of these situations, is mechanical energy being conserved? (Neglect, air resistance, friction and breaking) Check all that apply.Child on a swing


Pendulum


Bow and Arrow

Answers

Answer:

Neglecting, air resistance, friction and breaking, all the condition has conservation of mechanical energy.

Explanation:

  • The law of conservation of mechanical energy suggests that the mechanical energy in a locked system with out any destructive forces like friction or air resistance remains always the same (constant).
  • The energy may be converted between kinetic energy, potential energy, gravitational potential but energy do not get decreased in any cases as mentioned in the option.
  • So all the cases mentioned above shows the conservation pattern of mechanical energy.

When a wire is made thicker its resistance what?

Answers

Making a wire thicker has the same effect as making a road wider. It makes it easier for the electron traffic to flow. The resistance decreases, and the current (traffic) increases.

The total amount of mass in a system remains constant regardless of the changes that take place in that system.
Energy is neither created or destroyed; it only changes form.
Half-way down the ramp, PE = 50J and KE = 50J.
In this energy pyramid, all the energy from level is transferred to the next level.
In a closed system, i.e., a system that isolated from its surroundings, the total energy of the system is conserved.

Answers

All the statements regarding law of conservation of energy are true except for statement 2 stating energy changes half way down the ramp.

What is law of conservation of energy?

According to law of conservation of energy, it is evident that energy is neither created nor destroyed rather it is restored at the end of a chemical reaction .

Law of conservation of mass and energy are related as mass and energy are directly proportional which is indicated by the equation E=mc².Concept of conservation of mass is widely used in field of chemistry, fluid dynamics.

Law needs to be modified in accordance with laws of quantum mechanics under the principle of mass and energy equivalence.This law was proposed by Julius Robert Mayer in the year 1842.Energy of an isolated and closed system remains constant.
