False. Bases are substances that dissociate(break down) to give off hydroxide ions in aqueous solutions. The hydroxide ions are what makes them basic.
The top triangle has a vertical leg of "x", an angle opposed of 18 degrees, and a horizontal leg of d.
So tan (18) = x/d
and d = x/tan (18)
The bottom triangle has a vertical leg of "35-x", an angle opposite of 14 deg.and a horizontal leg of "d".
So tan (14) = (35-x)/d and d = (35-x)/tan (14)
Solving for "d":
x / tan(18) = (35-x)/tan14
(tan14)x = 35tan18-(tan18)x
x (tan14 + tan18) = 35tan18
x = 11.3722/0.5742
x = 19.81 ft. (distance the lady is from the pole)
Answer:
10N
Explanation:
Given data
Work done = 200J
distance= 20m
We want to find the applied force
From
Work done= Force * distance
substitute
200= F*20
F= 200/20
F= 10N
Hence the force applied is 10N
