algol [13]

Answer:

Explanation:

Given

current required $I=110 mA$

Internal Resistance $R=300 \Omega$

According to ohm law

Current flows in a conductor is directly Proportional to the voltage applied.

$V\propto I$

$V=IR$

$V=110\times 10^{-3}\times 300$

$V=33 V$

An engineer is designing a spring to be placed at the bottom of an elevator shaft. If the elevator cable should happen to break

Anuta_ua [19.1K]

Answer:

$k = 9876 N/m$

Explanation:

As per energy conservation we know that

initial total gravitational potential energy = final spring potential energy

so we have

$mg(h + x) = \frac{1}{2}kx^2$

also we know that maximum acceleration will be 5.3 g

so it is given as

$a = \frac{k}{m} x$

so we have

$x = \frac{ma}{k} = \frac{5.3 mg}{k}$

$mg(h + \frac{5.3 mg}{k}) = \frac{1}{2}k(\frac{5.3mg}{k})^2$

$mg(h + \frac{5.3 mg}{k}) = \frac{14.045(mg)^2}{k}$

$h + \frac{5.3mg}{k} = \frac{14.045 mg}{k}$

$h = \frac{8.745mg}{k}$

$k = \frac{8.745 (1439)(9.81)}{12.5}$

$k = 9876 N/m$
