Answer:
ΔL = 5.09x10^-5 m
Explanation:
data provided by the exercise:
m = 56 kg
L = 35 cm = 0.35 m
r = 1.5 cm = 0.015 m
Y = 1.6x10^10 N/m^2
F = 3 m*g
A = pi*r^2
The Young´s modulus is equal to:
Y = (F/A)/(ΔL/L) = (F*L)/(A*ΔL)
Clearing ΔL, we have:
ΔL = (F*L)/(A*Y) = (3*56*9.8*0.35)/(pi*(0.015^2)*1.6x10^10) = 5.09x10^-5 m

Explanation:. The vending machine holds 10 bags of pretzels and 8 packs of cheese crackers. Both the pretzels and crackers dispenseat 2 bags per hour. How many hours will elapse when there is the same number of snacks remaining in the vending machine? How many of each item will there be at this point?Equation1______________________________Equation2_______________________________Hours: ___________________________ Items: ____________________________What does each equation have n common? ______________________How does this affect the solution?
Answer:
see below
Explanation:
according to newton's second law of motion,
F = MA
where F is the resultant force
m is the mass
a = acceleration
so suppose the mass of the bowling ball is 10 kg
and the mass of golf ball is 1 kg
and the force applied on both of them is 5 N
substitute the values in the formula
for the bowling ball
5 = 10 x a
a = 0.5 ms²
for the golf ball
5 = 1 x a
a = 5 ms²
so which accelerated more the golf ball right?
so last option is the answer
