A tank 4 m long, 3 m wide, and 2 m deep is filled to the brim with 192 000 N
of paraffin. What is the pressure at the base of the tank?

16,000 N/m^2

Explanation:

Given;

Force = weight of fluid = 192,000N

Length of tank l = 4 m

Width w = 3 m

depth d = 2 m

Pressure is the measure of the force acting perpendicular to a surface per unit area.

Pressure = force/area

Pressure = F/A

Area A at the base = length × width = l×w

Pressure = F/(l×w) = 192000N/(4×3)m^2

Pressure = 16,000 N/m^2

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.

the components of a vector are the parts of the vectors that are to each other.
