Question

Mechanical advantage is calculated by using the formula:

a
Length of Slope (L) / Height of slope (H)
b
Height of Slope (H) / Length of Slope (L)
c
Normal Force/ Acceleration
d
Force of Friction/Gravity
Question 19 (2 points)
Match the following terms to their correct answer.

Column A
1.
1 Joule:
1 Joule
2.
Work formula:

3.
Pulley:
Pulley
4.
Inclined Plane:
Inclined Plane
Column B
a.Skateboard Ramp
b.Zipline
c.1 N x m
d.W= FD

Answer 1

For the first question regarding mechanical advantage, the correct formula is:

**a. Length of Slope (L) / Height of slope (H)**

---

For the matching question, here are the correct matches:

1. **1 Joule:**
**c. 1 N x m**

2. **Work formula:**
**d. W = FD**

3. **Pulley:**
**b. Zipline** (Note: This is somewhat unconventional, as a pulley system usually refers to a system of wheels and ropes, but if we consider a zipline as using a pulley mechanism in a broader sense, it can fit here.)

4. **Inclined Plane:**
**a. Skateboard Ramp**

So the final matches are:
1 - c
2 - d
3 - b
4 - a
