If you unbend a paper clip made from 1.5 millimeter diameter wire and push one end against the wall, what force must you apply t

vampirchik [111]

Answer:

The force is $F = 21.48 \ N$

Explanation:

From the question we are told that

The diameter of the wire is $d = 1.5 \ mm = 1.5 *10^{-3} \ m$

The pressure is $P = 120 \ a.t.m = 120 * 101.3 *10^{3} = 12156000 Pa$

Generally the radius of the of the wire is

$r = \frac{d}{2}$

=> $r = \frac{ 1.5 *10^{-3}}{2}$

=> $r = 7.5 *10^{-4} \ m$

The Area is evaluated as

$A = \pi r^2$

=> $A = 3.142 * 7.5 *10^{-4}$

=> $A = 1.7673*10^{-6} \ m^2$

Generally pressure is mathematically represented as

$P = \frac{F}{A }$

=> $F = P* A$

=> $F = 12156000 * 1.767*10^{-6}$

=> $F = 21.48 \ N$

If a vector that is 3 cm long represents 30 km/h, what velocity does a 5 cm long vector which is drawn using the same scale repr

svp [43]

If 3cm represents 30km/h then that means 1cm represents 10km/h. So, a 5cm long vector will represent a velocity of 50km/h
