irina [24]

Answer:

Explanation:

a = F / m

where a is acceleration , F is thrust and m is mass

taking log and differentiating

da / a = dF / F - dm / m

(da / a)x 100 = (dF / F)x100 - (dm / m) x100

percentage increase in a = percentage increase in F - percentage increase in m

= percentage increase in acceleration a   = 39 - 13 = 26 %

required increase = 26 %.

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))
