1) Write a function that calculates the volume of a sphere with radius r for only values > 0, return 0 otherwise . V=4/3 Ï r^3
2) Write a function that finds you weight in stones using the formula. mstone = mkgx2.2/14
3) Write a function that takes some monetary amount from the user in dollars, and then display exact changes for this amount using the minimum number of coins. For example, $0.97 shows 3 quarters, 2 dimes, and 2 pennies.
Output:
change_it(97)
The change for 97 cents is:
3 quarters
2 dimes
2 pennies
Write an function to calculate both Ohms Law and Power transferred. The function takes i and r as inputs and prints the results (see output below). Calculate only if both i and r are > 0.
FORMULA
i is current, v is voltage, r is resistance, p is power
p = i * v # power = current * volatage
v = i * r # voltage = current * resistance
def ohms_law(i, r):
”’
i is current
r is resistance
”’
# check if both i and r are greater than 0
# calculate v and p
# PRINT v and p
omhs_law(5, 5)
v = 25 p = 125
omhs_law(-5, -5)
0
