Question

A force of 16N is distributed uniformly on
one of the surfaces of a cube of edge 8cm.
The pressure on the surface in N/m² is
1) 0.25
2) 25
3) 2500
4) 250​

Answer 1

Answer: The  pressure on the surface in N/m² is 2500 N/m²

Explanation:

F = 16N

$A=8*8*10^{-4}m^{2} \\P = \frac{F}{A} \\P = \frac{16}{64*10x^{-4} }\\\\\\=\frac{1000}{4 } = 2500pa$

= 2500pa                      or               2500N/m²

Answer 2

Explanation:

Ohm's Law is a formula used to calculate the relationship between voltage, current and resistance in an electrical circuit. To students of electronics, Ohm's Law (E = IR) is as fundamentally important as Einstein's Relativity equation (E = mc²) is to physicists. E = I x R
