Solution is attached in the pictures below
Answer:
The mass of the banana is m and it is at height h.
Applying the Law of Conservation of Energy
Total Energy before fall = Total Energy after fall
=
Here, total energy is the sum of kinetic energy and potential energy
+
=
+
(a)
When banana is at height h, it has
= 0 and
= mgh
and when it reaches the river, it has
= 1/2m
and
= 0
Putting the values in equation (a)
0 + mgh = 1/2m
+ 0
mgh = 1/2m
<em>cutting 'm' from both sides</em>
<em> </em>gh = 1/2
v = 
Hence, the velocity of banana before hitting the water is
v = 
Answer:
Explanation:
Best to look it up for better results. The measure of a metals ability to withstand tension or stress to it. Like when when metal is being pulled apart it would be the distance it's being pulled.

Note that the electric field lines begin from the higher voltage to the lower
Because the negative pole is lower voltage than the positive pole
The lines go out the positive charges and go in the negative charges
Then, the correct statement is:
<u>C. Source A is negatively charged and source B is positively charged.</u>
