Answer: A light bulb can be all of the following except option C (a consumer product if it is used to light the office of the board of directors.)
Explanation:
Products are classified as being BUSINESS or CONSUMER products according to the buyer's intended use of the product.
-Consumer products: these are sold goods that are used for personal, family, or household use. The intention of the buyer is for the products to satisfy his personal needs and desires. Example of some of the consumer products include: toothpaste, eatables and clothes.
Business products: products that are not for personal use but for the manufacturing of other goods are called business products.
Therefore a bulb is not serving as a personal use when used to light the office of the board of directors rather it's serving as a business product .

Given :
You fire a paintball from a paintball gun straight up into the air at 25.0 m/s.
To Find :
What is the ball velocity at the higher point that the ball reaches.
Solution :
We know, when ball is moving upward acceleration due to gravity is applied downward.
So, the ball will decelerate and when ball reaches maximum height its velocity will become zero.
Therefore, ball velocity is 0 m/s at maximum height.
Hence, this is the required solution.
Answer:
The most significant difference between the static and current electricity is that in static electricity the charges are at rest and they are accumulating on the surface of the insulator. Whereas in current electricity the electrons are moving inside the conductor.
