If a 100-N net force acts on a 50-kg car, what will the accelaration of the car be?

Answers

Answer 1
Answer: 2m/s^2   how to get it: since you already know the force and mass and the formula for force is force=(mass)(acceleration) you isolate the variable of acceleration which is a by dividing (m)(a) by (m) which equals f/m=a then you plug in your known numbers where they go so f=100N m=50kg   100N/50kg= 2 therefore the acceleration is 2m/s^2  hope this helped you!!!

What are 3 types of cells that helper T cells produce upon being an alarmed of an antigen? Thanks for your help!! :)

Answers

Whenever these are an alarming due to a foreign antigen, the Helper T cells, Memory T cells, and Cytotoxic T cells are being produced. Helper T cells to recognize the specific foreign antigen that is entering the body, Memory T cells to remember the specific foreign antigen that is attacking, and Cytotoxic T cells that are for the destruction of the foreign cells and produce cytokines to attract macrophages

An electroscope is a device that detects charge on objects that touch it or are brought near it. John rubs a piece of cotton fabric on a plastic rod and then touches the rod to the electroscope.What methods of charging does John use?

Answers

The answer is Static Electricity. When you say static electricity, there is a certain imbalance in the particles present on the surface of the material. That is why the electroscope was able to detect static electricity from the piece of cloth and plastic rod

Answer:

John charges the rod through friction, then charges the electroscope through conduction. D on edg2020

What do you mean by average velocity​

Answers

Answer:

Here is the answer. Hope this helps you!

Explanation:

Average velocity is the sum of initial and final velocity divided by 2. I t is the same as total Displacement divided by total time. Average velocity is calculated when the body is in non-uniform motion (also when total displacement and time is not given). The formula is as follows:

u + v/2 = v_(av)

Average velocity = Average speed

during motion in a straight line. therefore, the above mentioned formula can be used for calculating average speed as well, when the direction is one and only the same, that is, during motion in a straight line. The S.I unit remains the same-

m/s.

Since velocity is vector, average VELOCITY is also vector. However, Average SPEED is scalar as speed is scalar. both can be equal only when the distance = displacement and when they are following the same direction of motion.
