Answer:
Explanation:
If F is the applied force and θ is the applied angle from horizontal with positive angle below the horizon
Fnet = Fcosθ - μ(mg + Fsinθ)
The only variable you've actually given us is the friction coefficient.
You'll have to plug your own numbers in.
Remember, if the applied force is acting towards the floor, the normal force is increased as will be the friction force. The net force will decrease.
If the applied force is acting upward, the θ angle will be negative and the normal force is decreased along with the friction force. The net force will increase.
<span>Faraday is best known for his work regarding electricity and magnetism. His first recorded experiment was the construction of a voltaic pile with seven ha'penny coins, stacked together with seven disks of sheet zinc, and six pieces of paper moistened with salt water.</span>
Answer:
For every action there is an equal and opposite reaction is a statement of Newton's <u>third</u> law of motion
Explanation:
Newton's third law states that for every action there is an equal and opposite reaction.
This law says that when force is applied on any object then the object exerts an equal an opposite force. Here, force applied on the object is called the reaction force while the force applied by the object is called the reaction force.
For example: A person walking on a concrete road.
A person walking on a concrete road exerts a backward force on the road by his feet. This action force causes a reaction force by the concrete road of same magnitude but in forward direction. This helps the person to move forward.
Evidence from archaeological and genetic studies suggests that maize was bred and cultivated by early inhabitants of Mexico as early as ten thousand years ago. The early Mesoamericans managed to develop corn from its grassy ancestor by selective breeding. Maize was bred from a wild grain called teosinte.
