Answer:10cm3
Explanation:Volume Al = (27g Al)/(2.70g/cm3 Al) = 10cm3 Al. So, 27g of Al has a volume of 10cm3. *
Answer:
Coefficient of static friction will be equal to 0.642
Explanation:
We have given acceleration 
Acceleration due to gravity 
We have to find the coefficient of static friction between truck and a cabinet will
We know that acceleration is equal to
, here
is coefficient of static friction and g is acceleration due to gravity
So 
So coefficient of static friction will be equal to 0.642
Answer:
attracted
Explanation:
Electrons are negative.
A positively charged object will attract a negatively charged object
Answer:
<em>110.7Joules</em>
Explanation:
<em>Work is said to be done when the force applied to a body cause the body to move through a distance.</em> Mathematically:
Work done = Force * Distance
Given the following
Force = 270 -0 = 270N
Distance moved = 0.410m
Required
The work done
Substitute the given parameters into the formula
Workdone = 270 * 0.41
Workdone = 110.7Joules
<em>Hence the work done in pulling the bow is 110.7Joules</em>
