The equation E = mc2 relates energy andA. force
B. work
C. gravity
D. mass

Answers

Answer 1
Answer:

The equation E = mc² relates energy and mass and the correct option is option D.

The equation was formulated by Albert Einstein as part of his theory of special relativity. In this equation, "E" represents energy, "m" represents mass, and "c" represents the speed of light in a vacuum, which is approximately 3 x 10⁸ meters per second. The equation states that energy is equal to the mass of an object multiplied by the square of the speed of light.

This equation demonstrates the equivalence between mass and energy, suggesting that mass can be converted into energy and vice versa. It is a foundational equation in physics and has significant implications in understanding the relationship between matter and energy.

Thus, the ideal selection is option D.

What type of magnetism is present in a magnet that you use to place a photograph on the refrigerator? A. Induced
B. Superconducting
C. Contact
D. Permanent

Answers

Answer:

C) Contact

Explanation:

The magnet requires almost direct contact with the fridge to start its magnetic properties.

Answer:

Correct Answer is option D (permanent)

Explanation:

Permanent magnet

Permanent magnet is a magnet in which magnetic properties are present even in the absence of an external magnetic field. It has its own magnetic field.

Permanent type of magnetism is present in a magnet that we use to place a photograph on the refrigerator.This permanent magnet  is made up of powdered ferrite  and liquid plastic. The  mixture of ferrite and plastic is heated at a particular temperature and then this heated mixture is placed in a strong magnetic field. Due to this applied magnetic field this mixture is turned into a permanent magnet.

By this method of it requires less material to create a permanent magnet.
