Question

Python programming calculating energy using mass and energy of light using the formula E=mc**

Answer 1

# input values from user

mass = float(input("Please enter the mass in kilograms: "))

velocity_of_light = 299792458 # in meters per second

# calculate energy

energy = mass * velocity_of_light ** 2

# output result

print(f"The energy equivalent of a mass of {mass:.2f} kg is {energy:.2f} joules.")

Step-by-step explanation:

In the code above, the user is prompted to enter the mass in kilograms using the input() function. The code then calculates the energy equivalent to the mass using a predetermined speed of light and prints the result to the screen using the print() function. This code is efficient in calculations because it uses the exponential operator ** and the float numeric data type.
