<h2>
Answer: 469 feet</h2>
Explanation:
This problem is a good example of Vertical motion, where the main equation for this situation is:
(1)
Where:
is the height of the stone at 6s (the value we want to find)
is the initial height of the stone
is the initial velocity of the stone
is the time at which we need to find the height
is the acceleration due to gravity
Having this clear, let's find
from (1):
(2)
Finally:
This is the height of the stone at t=6s
Answer:
+14.0 m/s
Explanation:
we have mV + Mv = mU + Mu we solve for U = (mV + Mv - Mu)/m = (328*19.1 + 790*13 - 790*15.1)/328 = 14. Answer
Answer:

Explanation:
A point charge Q is placed at the center of a cube of side l.
We need to find the flux through one face of the cube. Let the flux is
.
There are 6 faces in a cube.
According to Gauss's law, net flux is given by :

As there are 6 faces of a cube, flux through one surface is :

So, the flux through one face of the cube is
.
