Answer:
32.087 m/s
Explanation:
Velocity Initial = 5.6 m/s
time= 2.7
acceleration = 9.81
Velocity final = ?
Vf = Vi + at
Vf = (5.6) + (9.81)(2.7)
Vf = 32.087 m/s
Answer:
Explanation:
To estimate the focal length of a convex lens follow the following steps.
1. take a convex lens.
2. Stand near a window which is just opposite to a wall.
3. Look at a tree which is far away from the window by the convex lens.
4. focus the image of the tree on the wall which is opposite to the window.
5. You wll observe that by changing the position of convex lens a sharp and inverted and small image is seen on the wall.
5. Now measure the distance between the lens and the wall.
7. This distance is the rough focal length of the convex lens.
Answer:
± (.021 ) ohm
Explanation:
In the addition of two physical quantities , the uncertainties are simply added .
So , net uncertainty in the value of R will be
± (.007 +.014)
=± (.021 ) ohm
