The effort applied = 200 N
<h3>Further explanation</h3>
Equilibrium :

Total length = 1.75
The distance between the fulcrum and the load is 0.5 m ⇒ d₁=0.5 m
The distance between the fulcrum and the force applied :

A load of 500N ⇒ F₁=500 N
The force applied :

That part of the wave is called a compression.
Answer:
Prevost's theory of exchanges stated that each body radiates to, and receives radiation from, other bodies. ... Prevost went on to comment that "The heat of several portions of space at the same temperature, and next to one another, is at the same time in the two species of equilibrium."
Explanation:
Answer:
t = 1023.9 seconds
Explanation:
Given that,
The average velocity of a Mustang, v = 33m/s
Distance, d = 21 miles = 33789 m
Let the driver takes t seconds. So,
Speed = distance/time

So, it will take 1023.9 seconds to complete the course.
