Answer:
Force the floor exerts on the passenger is 833 N.
Explanation:
- Weight of passenger (
) = mg = 85 × 9.8 N = 833 N
- Force the floor exerts on the passenger (
) = ?
- For the elevator with the speed as 2.0 m/s the net force is zero, it means that the force is balanced.
i.e. = - = -mg = 833 N
hence is 833 N
- If the lift was not at a constant speed i.e. if it had acceleration (
) then the case would be different.
Answer:
deductive reasoning usually follows steps .
- That is, how we predict what the observations should be if the theory were correct
To solve the problem we will simply perform equivalence between both expressions. We will proceed to place your units and develop your internal operations in case there is any. From there we will compare and look at its consistency
At the same time we have that
Therefore there is not have same units and both are not consistent and the correct answer is B.
