The center of gravity is a SIKKE bro you really thought I’d give the answer of something so simple
To solve this problem we will begin by finding the pressure through density and average depth. Later we will find the Force, by means of the relation of the pressure and the area.

Here,
h = Depth average
= Density
Moreover,

Replacing,


Finally the force



The answer to your question is,
A meteoroid.

Answer:
150m
Explanation:
The relation of speed/time and distance/time is a derivative/integral one, as in speed is the derivative of distance (the faster you go, the faster the distance changes, duh!).
So we need to compute the integral of speed over time from 0.0s to 5.0s.
The easiest way here is to compute the area under the line (it's going to be faster than computing the acceleration and using a formula of distance based on acceleration).
The area under the line is a trapezoid with "height" 5s, and the bases 10m/s and 50m/s. Using the trapezoid area formula of h*(a + b)/2
distance = 5s * (10m/s + 50m/s) / 2 = 5s * 60m/s / 2 = 5s * 30m/s = 150m
Alternatively, we can use the acceleration formula:
a = (50m/s - 10m/s)/5s = 40m/s / 5s = 8m/s^2
distance = v0 * t + a * t^2 / 2 = 10m/s * 5s + 8m/s^2 * (5s)^2 / 2 = 50m + 8m * 25 / 2 = 50m + 100m = 150m.
Answer: 9/4n
Explanation:
Let's take T to represent tank
When n litres of fuel was added to tank that was 1/3 full = n + 1/3T
The tank was 7/9T
n+1/3T = 7/9T
n =7/9T - 1/3T
n = 4/9
If a full tank is taken to be 1 = 9/9
Hence, we will have 1 = x × n
1 = x × 4/9
x = 9/4
Hence 9/4 of n = 9/4n
