Shalnov [3]3 years ago
7 0

Answer:

4

Explanation:

Relative Biological Effectiveness (RBE) =

Standard Radiation dose / Test Radiation dose

for achieving the same biological effect.

The absorbed radiation dose is measured in units of Gyt(Gray in tissue).

In the given scenario, Standard radiation dose of 250 KVp X-rays = 16 Gyt

Corresponding Test Radiation dose = 4 Gyt

Therefore, Relative Biological Effectiveness = 16/4 = 4

Shtirlitz [24]

Answer:

def newton(n):

       #Define the variables.

       t = 0.000001

       esti = 1.0

       #Calculate the square root

       #using newton method.

       while True:

               esti = (esti + n / esti) / 2

               dif = abs(n - esti ** 2)

               if dif <= t:

                       break

   

       #Return the result.

       return esti

#Define the main function.

def main():

   

       #Continue until user press enters.

       while True:

               try:

         

                       #Prompt the user for input.

                       n = int(input("Enter a number (Press Enter to stop):"))

                       #display the results.

                       print("newton = %0.15f" % newton(n))

     

               except:

                       return

#Call the main function.

Change the function definition for myint so that xyzfunc uses the same memory locations for myint as in the calling program.
sattari [20]

Answer:

b) void xyzfunc (int &myint);

Explanation:

To use the same memory location as the variable in the calling function we have to pass the variable by reference means passing the same address to the function.So to do that we have use & operator which stands for address.

We will do this as following:-

void xyzfunc (int * myint);

Hence the answer is option b.
