Class 1 lever
Explanation:
In a class 1 lever, the fulcrum is placed between the effort and the load. This lever systems is the most common.
- The effort is the force input and the load is the force output
- The fulcrum is a hinge between the load and effort.
- Movement of the effort and load are in opposite directions.
- There are other classes of lever like the class 2 and 3.
- They all have different load, fulcrum and effort configurations

Answer:
C. Add all the force vectors
Explanation:
The net force acting on an object is the vector sum of all the forces on the object.
Remember, Newton's first law tells us a body at rest will remain at rest or that in uniform motion will continue in motion unless acted by unbalanced forces.These unbalanced forces act in all direction towards the body thus to get the net force you require a summation of all these force with respect to their magnitudes and directions.
For example a force of 3N towards the East direction acting on a body and another force of 2N towards the West direction on the same body will generate a net force of 1N towards the East direction.
Answer:
Mike will receive an electric shock
Explanation:
Human body is a conductor of electricity. When lightning strikes rod and give it negative charge, the rod will dissipate its charge as soon as it comes in contact with earth via conduting material. Mike will receive a severe electric shock as negatice charge pass through his body to other rod and to the ground.His body will feel numb. He may also get unconscious.
My favorite fictional character is definitely Eren from Attack on Titan because he is strong, caring, and protects the people he loves
My least favorite is Bakugo from My Hero Academia because he is toxic, lowdown, and has severe anger issues.
Hi!
The correct option is B.
<h3>Explanation</h3>
Evolution is a biological phenomena which descries how the heritable characteristics of a species change over successive generations. These characteristics change as a result of a mutation, natural selection or genetic recombination (to list a few).
Darwin's theory of evolution explained how this phenomena occurs with respect to natural selection. The theory goes on to explain how a species diverges from a common ancestor into two or more different species (meaning different species may have common ancestor). This is a slow process as it can take thousands of years.
Hope this helps!
