select the correct answer.\nvictoria has a crate of vegetables that weighs 100 newtons. she exerts a force of 100 newtons to lift the crate with a pulley. whats the mechanical advantage in this situation?\na. less than 1\nb. equal to 1\nc. equal to 0\nd. more than 1
Answer
Explanation:
Step1: Recall mechanical - advantage formula
The formula for mechanical advantage (MA) of a machine is $MA=\frac{\text{Load}}{\text{Effort}}$.
Step2: Identify load and effort values
The load is the weight of the crate, which is 100 newtons. The effort is the force exerted to lift the crate, which is also 100 newtons.
Step3: Calculate mechanical advantage
Substitute the values into the formula: $MA = \frac{100}{100}=1$.
Answer:
B. equal to 1
