An oil tanker has a mass of 400,000 tonnes. It is 500m long and 40m wide. A. What is the minimum depth of the harbor it requires.?
B. Calculate the downward force
C. State the upward force
D. Draw a diagram to show the forces acting on the tanker.

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..
