diamong [38]

Answer:

The code is written in python in the explanation section below

Explanation:

a_feet = int(input("Input the feet of the first fabric: "))

a_inches = int(input("input the size in inches for the first piece of fabric: "))

b_feet = int(input("input the size in Feet for the second piece of fabric: "))

b_inches = int(input("Enter the size in Inches for the second piece of fabric: "))

sum_inches = a_inches + b_inches

inches_to_feet = sum_inches // 12

rem_from_div = sum_inches % 12

sum_feet = a_feet + b_feet + inches_to_feet

print("Feet: {} Inches: {}".format(sum_feet, rem_from_div))

A ball is projected horizontally from the top of a cliff. At the same moment, a second identical ball is dropped from rest from
almond37 [142]

Answer:3

Explanation:

First ball is thrown with horizontal velocity while other ball is dropped from cliff such that both have zero vertical velocity. So both balls have to cover a distance equal to the height of cliff with same initial velocity.

time taken is given by t=\sqrt{\frac{2h}{g}}

where h=height of cliff

g=acceleration due to gravity

horizontal velocity to first ball will make the ball to travel more horizontal distance as compared to second ball.

Option 3 is correct
