How Do You Calculate Rotational Kinetic Energy?

Rotational kinetic energy can be expressed as: Erotational=12Iω2 E rotational = 1 2 I ω 2 where ω is the angular velocity and I is the moment of inertia around the axis of rotation. The mechanical work applied during rotation is the torque times the rotation angle: W=τθ W = τ θ .

How do you calculate stress of a material?

As expected by the units, stress is given by dividing the force by the area of its generation, and since this area (“A”) is either sectional or axial, the basic stress formula is “σ = F/A”.

What are the uses of refrigerant?

A refrigerant is chemical compound that is used as the heat carrier, which changes from gas to liquid and then back to gas in the refrigeration cycle. Refrigerants are used primarily in refrigerators/freezers, air-conditioning, and fire suppression systems.

Substitution Reactions – Types

Substitution Reactions are of two types naming nucleophilic reaction and electrophilic reactions.

How do you explain area and volume?

The area is the amount of space occupied by a two-dimensional flat object in a plane. Volume is defined as the space occupied by a three-dimensional object. The unit of area is in square units. The unit of volume is in cubic units.

What are examples of qualitative research questions?

What is mocking in the Bible?

According to the gospel narratives, Jesus had predicted that he would be mocked (Matthew 20:19, Mark 10:34, and Luke 18:32). The mocking of Christ took place in three stages: immediately following his trial, immediately following his condemnation by Pontius Pilate, and when he was being crucified.

What is the straight line treatment of optics?

More to Know! If an opaque object on the path of light becomes very small, light has a tendency to bend around it and not walk in a straight line – an effect known as the diffraction of light. Then the straight-line treatment of optics using rays fails.

How do you solve an unsolvable problem?

  6. Tip #5: Come up with the answers yourself.

What are uniform and non-uniform motion give four examples for each type of motion?

Answer: When a body covers equal distances in a straight line, equal intervals of time are called uniform motion. Example: a car moving at 20km/h in a straight line. When a body covers unequal distance in equal intervals of time in a straight line is called non-uniform Example : spinning wheel.

What is uniform circular motion Give 4 examples of it?

Uniform Circular Motion Examples

The gravitational force from the earth makes the satellites stay in the circular orbit around the earth. The motion of electrons around its nucleus. The motion of blades of the windmills. The tip of second's hand of a watch with circular dial shows uniform circular motion.
