Metamorphic rock this possess often occurs in the mantle
To solve this problem we will use the concepts related to hydrostatic pressure. Which determines the pressure of a body at a given depth of a liquid.
Mathematically this can be described as

Here
= Density
g = Gravity
h = Height (Depth)
If we replace the values given in the equation we will have to


Therefore the pressure at the bottom will be 9.8kPa
Answer:
The mass is 1200 kilograms
Explanation:
Because Force is equal to mass times acceleration (F=m×a)
F=m×a
1800N=?×1.5
1800÷1.5=1200
1800N=1200Kg×1.5
