The correct answer is 14.2 lb which is choice D.
Let:
F = minimum force required to prevent ball from rolling down the ramp
The formula will be:
F = w * sin theta
F = w * sin (39 degrees)
F = 22.6 * sin (39)
= 14.2 lb (this is rounded to the nearest tenth)
Answer:
Step-by-step explanation:
10^4 = 10000
1.7 × 10^4 = 1.7 × 10000
= 17000
10^-2 = 1/10^2= 1/100
8.5 × 10^-2 = 8.5 × 1/100
= 17/200
Final answer = 17000 × 17 / 200
= 1445
Plz mark it as brainliest
Log4 + logX + log13 = 0
logX = -log13 - log4
logX = -1.716
x= 10^[-1.716]
x= 0.019 A
