Answer:

$I=38.181\ A$ is the current through the body of the man.

$E=34.5\ J$ energy dissipated.

Explanation:

Given:

time for which the current lasted, $t=43\times 10^{-6}\ s$

potential difference between the feet, $V=21000\ V$

resistance between the feet, $R=550\ \Omega$

$I=\frac{V}{R}$

$I=\frac{21000}{550}$

$I=38.181\ A$ is the current through the body of the man.

<u>Energy dissipated in the body:</u>

$E=I^2.R.t$

$E=38.181^2\times 550\times 43\times 10^{-6}$

$E=34.5\ J$

A bathtub has 62.7 kg of water at 31.0

Bogdan [553]

m = mass of water in bathtub = 62.7 kg

$T_{ti}$ = initial temperature of water in tub = 31 c

M = mass of water added = ?

$T_{ai}$ = initial temperature of water added = 76 c

T = final equilibrium temperature of the system = 40.3 c

c = specific heat of water = 4186

Using conservation of heat

Heat gained by water in tub = Heat lost by water added

m c (T - $T_{ti}$ ) = M c ( $T_{ai}$ - T)

m (T - $T_{ti}$ ) = M ( $T_{ai}$ - T)

(62.7) (40.3 - 31) = M (76 - 40.3)

M = 16.3 kg

Marianna [84]

<h3><u>Answer;</u></h3>

B.A heat engine that uses work to move heat

<h3><u>Explanation;</u></h3>

A heat engine involves a thermodynamic process that converts the heat supply in it into mechanical work.
A heat engine makes use of the properties of thermodynamics to transform heat into work. Gasoline and diesel engines, jet engines, and steam turbines that generate electricity are all examples of heat engine
