1. Draw an outline of your shoe on a graph paper. Calculate the area of the shoe in cms and convert it to m2
1 grid box on the graph sheet is 1 cm2. So, 1 cm = 1 cm x 1 cm
2.
Now, calculate the area of your shoes.
Area of one shoe =
?
Total area of your shoes, A = Area of one shoe x 2 =
3. Now, find out your weight
(W = mx where m is your mass in kg and g is acceleration due to gravity, which is equal to 10 m/s
Your weight, W = (mass) kg x 10 m/s2 =
N
w
Pa
4. So, the pressure applied by you on the ground, P =
А
N
​

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
