Work = (weight) x (distance lifted)
= (100 N) x (0.5 m)
= 50 joules.
If you carry the sled level all the way to your house, you're not moving it
against gravity.
Although you're huffing and puffing and sweating by the time you reach
your house, still, according to the Physics definition of work, you have
done NO work on the sled all the way home.
A jug would hold more volume than a mug
Answer:
Electric flux, 
Explanation:
It is given that,
Electric field, 
We need to find the electric flux through a circular area of radius 2.66 m that lies in the xy-plane. 
The electric flux is given by :


Since, k.k=i.i=j.j = 1
So,


So, the electric flux through a circular area is
.Hence, this is the required solution.
Explanation:
The given data is as follows.
Fluid is water so, density 
Weight flow rate = 500 lbf/s = 2224.11 N/sec
Cross-sectional area (A) = 
= 0.05184 
Hence, weight flow rate will be given as follows.
w = 
2224.11 N/sec = 
V =
m/s
= 4.373 m/s
Thus, we can conclude that average velocity in the given case is 4.373 m/s.
