Energy absorbed by the radiologist is 1.775*10^-6J.

To find the answer, we have to know about the radiation.

<h3>How much energy has she absorbed?</h3>
  • We have the expression for dose of absorption as,

           D=\frac{E}{m}

where; E is the energy absorbed and m is the mass of the body.

  • From the above expression, substituting appropriate values given in the question, we get,

         E=D*m=2.5*10^{-6}J/kg*71kg=1.775*10^{-4}J

Thus, we can conclude that, the Energy absorbed by the radiologist is 1.775*10^-6J.

A 350-km-long high-voltage transmission line 2.00 cm in diameter carries a steady current of 1,010 A. If the conductor is copper
Masja [62]

Answer:

t = 47 years

Explanation:

To find the number of years in which the electrons cross the complete transmission, you first calculate the drift velocity of the electrons in the transmission line, by using the following formula:

v_d=\frac{I}{nAq}         (1)

I: current = 1,010A

A: cross sectional area of the transmission line = π(d/2)^2

d: diameter of the transmission line = 2.00cm = 0.02 m

n: free charge density = 8.50*10^28 electrons/m^3

q: electron's charge = 1.6*10^-19 C

You replace the values of all parameters in the equation (1):

v_d=\frac{1010A}{(8.50*10^{28}m^{-3})(\pi(0.02m/2)^2)(1.6*10^{-19}C)}\\\\v_d=2.36*10^{-4}\frac{m}{s}

with this value of the drift velocity you can calculate the time that electrons take in crossing the complete transmission line:

t=\frac{d}{v_d}=\frac{350km}{2.36*10^{-4}m/s}=\frac{350000m}{2.36*10^{-4}m/s}\\\\t=1,483,050,847\ s

Finally, you convert this value of the time to years:

t=1,483,050,847s*\frac{1\ year}{3.154*10^7s}=47\ years

hence, the electrons take around 47 years to cross the complete transmission line.

A certain Diesel engine performs 372 of work in each cycel wth an efficieny of 33.0 percent.How much energy is transferred from
lesantik [10]

Answer:

122.76J

Explanation:

Given data

work done= 372 Joules

efficiency= 33%

Required

We want to compute the value of the work that is 33%

= 33/100* 372

= 0.33*372

= 122.76J

Hence 122.76J of work is transferred from the engine to the exhaust
