A drowsy cat spots a flower pot that sails first up and then down past an open window. The pot was in view for a total of 0.56 s

liberstina [14]

Answer:

$h = 0.028 m$

Explanation:

As we know that

$d = \frac{v_2 + v_1}{2} t$

here we have

$1.95 = \frac{v_2 + v_1}{2}(0.56)$

$v_2 + v_1 = 6.96$

also we know

$v_2 - v_1 = at$

$v_2 - v_1 = (9.81)(0.56)$

$v_2 - v_1 = 5.49$

so we have

$v_2 = 6.23 m/s$

$v_1 = 0.74 m/s$

so the height above window is given as

$v_f^2 - v_i^2 = 2 a d$

$0.74^2 - 0 = 2(9.81)h$

$h = 0.028 m$

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

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

=> $F = P* A$

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

=> $F = 21.48 \ N$
