1) Write a function that calculates the volume of a sphere with radius r for only values > 0, return 0 otherwise . V=4/3

? 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 Ohm’s 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

1. Frida Kahlo’s Symbolism. (at the bottom left on this link you can click to see her work) http://www.pbs.org/weta/fridakahlo/ (????????)Frida Kahlo’s work is infused with symbolism, such as a monkey on her shoulder. In Mexican mythology, a monkey represents the patron of the dance and is a symbol of lust.
