Categorize each quantity as being either a vector or a scalar. Explain your reasoning. a. 20 degrees Celsius b. 256 bytes c. 4000 Calories

a. Scalar quantity

b. Scalar quantity

c. Scalar quantity

Explanation:

Generally, all physical quantities can be categorized into vector or scalar. Vector quantities can be described by both magnitude and direction, while scalar quantities can be described only by magnitude.

a. 20 degrees Celsius is a measure of a definite value of temperature, thus it is a scalar quantity. As temperature has no direction.

b. 256 byte is the storage capacity of an electronic device. It is a scalar quantity since it is described only by magnitude and no direction.

c. 4000 Calories is an amount of energy in a given substance. Thus, it is a scalar quantity.

fgravity=10x10=100n case 1

fgravity=30x20=600n case 2

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy
