Answer:
100 N force have to lift for the board to be carried
Explanation:
Given data
L = 3.00 m
F1 = 60.0 N
w = 160 N
to find out
magnitude F2 of force
solution
we know that F1 and F2 sum is equal to weight of board
so that we can say
F1 + F2 = W
so
F2 = W - F1
put the value W and F1
F2 = 160 - 60
F2 = 100 N
so 100 N force have to lift for the board to be carried

Let height of twin falls = x
height of seven falls = 2.5x
x + 2.5x = 420
3.5x = 420
x = 420/3.5 = 120
so twin falls = x = 120 ft
seven falls = 2.5x = 300 ft
The quantities that are equal to total of the individual values within a circuit are: A) The current in a parallel circuit and the voltage in a series circuit
