A jogger hears a car alarm and decides to investigate. While running toward the car, she hears an alarm frequency of 872.10 Hz.

Nata [24]

Answer:

v = 4.18 m/s

Explanation:

given,

frequency of the alarm = 872.10 Hz

after passing car frequency she hear = 851.10 Hz

Speed of sound = 343 m/s

speed of the jogger = ?

speed of the

$v_f = \dfrac{872.10-851.10}{2}$

$v_f =10.5\ Hz$

v_o = 872.1 - 10.5

$V_0 = 861.6\ Hz$

The speed of jogger

$v = \dfrac{v_1 \times 343}{v_0}-343$

$v = \dfrac{872.1 \times 343}{861.6}-343$

v = 4.18 m/s

The total surface area of the human body is 1.20 m2 and the surface temperature is 30∘C=303∘K. If the surroundings are at a temp

zalisa [80]

To solve this problem we must consider the expressions of Stefan Boltzmann's law for which the rate of change of the radiation of energy H from a surface must be

$H = Ae\sigma T^4$

Where

A = Surface area

e = Emissivity that characterizes the emitting properties of the surface

$\sigma$ = Universal constant called the Stefan-Boltzmann constant $(5.67*10^{-8}m^{-2}K^{-4})$

T = Absolute temperature

The total heat loss would be then

$Q = H_2 -H_1$

$Q =Ae\sigma T_2^4-Ae\sigma T_1^4$

$Q = Ae\sigma (T_2^4-T_1^4)$

$Q = (1.2)(1)(5.67*10^{-8})(303^4-280^4)$

$Q = 155.29J$

Therefore the net rate of heat loss from the body by radiation is 155.29J
