Answer: 75 N

Because we're finding the force, we need to use F = ma. M (Mass) = 25 and A (Acceleration) = 3. Multiply 25(3) to get 75. So, you're answer should be 75 N.

Lemur [1.5K]

The effort applied = 200 N

<h3>Further explanation</h3>

Equilibrium :

\tt F_1.d_1=F_2.d_2

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 :

\tt 1.75-0.5=1.25~m\rightarrow d_2=1.25~m

A load of 500N ⇒ F₁=500 N

The force applied :

\tt 500\times 0.5=F_2\times 1.25\\\\F_2=\dfrac{500\times 0.5}{1.25}=200~N

State the prevost's theory of heat exchange​
dezoksy [38]

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."

saw5 [17]

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

t=\dfrac{d}{v}\\\\t=\dfrac{33789}{33}\\\\t=1023.9\ s

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