Answer:
the acceleration due to gravity, g of the cylinder is 9.81m/s2
Explanation:
since the cylinder is rolling down from a hill, the acceleration due to gravity of any object coming down from the atmosphere is always constant which is g=9.8m/s2 or approximately 10m/s2
A myoplasty is the surgical repair of a muscle.
Answer:
A) 
B) 
C) 
Explanation:
Coulomb's Law is

where r is the distance between the two point charges.
The question clearly asks the unit vector expressions of the force that q exerts on the other charge. So, we do not need to find the force, but only the distance vector, r, between charges, and then we can derive the unit vector pointing only the direction of the force.
A) 
B) 
C) 
Answer:
velocity (v) =distance(s) ÷ time (t)
Explanation:
v=s÷t
s=v×t
s=3×3.4
s= 10.2m
