Answer:

Explanation:
From the question we are told that:
Dimension of plate: 
Depth submerged 
Water density 
Gravity 
Generally the equation for Volume is mathematically given by



Therefore The mass of Plate is



Generally the equation for Force on the plate is mathematically given by
F=ma




Answer:
c
Explanation:
force is how hard it is pulled or pushed
Using the given equation you get:
E = 1.99x10^-25 / 9.0x10^-6
Divide 1.99 by 9.0: 1.99/9.0 = 0.22
For the scientific notation, when dividing subtract the two exponents:
25 -6 = 19
So you now have 0.22 x 10^-19
Now you need to change the 0.22 to be in scientific notation form:
2.2 x 10^-20
The answer is B.
B) not work ,because the water would freeze
