Answer:
Wooden poles are rigid. That means that if you apply a force on the top of it, energy will travel directly to the ground (and you will just feel a very strong normal force) and the pole won't store any energy. An elastic pole will flex, storing energy that won't go directly to the ground, but as it recovers it's original shape, half of this stored potential energy will transforme to kinetic energy for the athlete, giving them energy to jump higher.
Explanation:
Explained above.
Hey there!
I believe the answer is A. The boiling temperature did not change
Hope this helps you!
God bless ❤️

It might be a or d not too sure though
linear charge density of system of two line charges is given as
now as we know that electric field due to a line charge at some distance from it is given by
so here we will first find the electric field of first line charge at the position of other line charge
now as we know that
here q = charge on the line charge system at which force is required
E = electric field on that system of charge where force is required
now we can find the charge by
Now using the above formula
so force on the part of wire is F = 0.0811 N
