Let the forces on two pillars are N1 and N2
so we will have force balance equation as
also by torque balance we will have
![N_2\times L = 40000 ]times \frac{L}{2} + 19600 \times 8](https://tex.z-dn.net/?f=N_2%5Ctimes%20L%20%3D%2040000%20%5Dtimes%20%5Cfrac%7BL%7D%7B2%7D%20%2B%2019600%20%5Ctimes%208)
here we know that
L = 20 m
Answer:
200 N
Explanation:
Applying,
The force a golie must exert on the ball is,
F = ma...................... Equation 1
Where m = mass of the ball, a = acceleration of the ball.
But,
a = Δv/t............... Equation 2
Where Δv = change in velocity, t = time.
Substitute equation 2 into equation 1
F = m(Δv/t)............... Equation 3
From the question,
Given: m = 0.8 g, t = 0.1 s, Δv = 25 m/s
Substitute these values into equation 3
F = 0.8×25/0.1
F = 200 N
The potential energy is 4.10 J
Explanation:
The potential energy of a body is given by
where
m is the mass of the object
g is the acceleration of gravity
h is the height of the object relative to the ground
For the lemming in this problem we have
m = 0.078 kg is its mass
h = 5.36 m is the height above the ground
is the acceleration of gravity
Solving the equation,

In 1784, Benjamin Franklin made what may have been the first connection between volcanoes and global climate while stationed in Paris as the first diplomatic representative of the United States of America. He observed that during the summer of 1783, the climate was abnormally cold, both in Europe and back in the U.S. The ground froze early, the first snow stayed on the ground without melting, the winter was more severe than usual, and there seemed to be "a constant fog over all Europe, and [a] great part of North America."
I HOPE THAR HELPS IF NOT IM SORRY:(
Explanation:
If you want to get speed, u have to divided distance over time
The lowest speed will lose
