He Given a brick shown above and its length, width, and height
are 10.0cm, 2.00cm, and 5.00cm respectively. The pressure
exerted by the brick on the floor is different when the brick is
placed in different ways. If the minimum pressure exerted by
the brick on the floor is 100.0 Pa, what is the forced exerted on
the floor in newtons (N)?

answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.

explanation:

i need mutiple choices

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
