Calculate the pressure exerted by a man having mass 50 kg standing on one feet having area 500cm2

9800 Pa

Explanation:

Data: pressure-?

Force- mass ×acceleration

= 50× 9.8m/s^2

=490N

Area= 500cm^2=0.05m^2

pressure= force/ area

p=F/A

P= (490N)/( 0.05m^2)

=9800 Pa

hello there!

your answer is a “generator”

a generator does not create energy but instead it transforms it.

it’s basically a motor working in reverse.

d

explanation:

v=uf/(u-f)

= 5.10/(5-10) convex lens has positive focal length

=50/-5

=-10 cm (formed at other side)
