Answer:
hydrostatic force is 327000.00 N
Explanation:
given data
base = 4 m
height = 5 m
density of water = 1000 kg/m3
to find out
hydrostatic force
solution
we know this is a triangle so we consider here a small strip PQ whoes area da in with length x and width dy
so area will be
da = base/H × height = base/H × y
so da = x dy = base/H × y dy
and we know pressure = ρ × g × h
here h = y
hydrostatic force = pressure × area
df = (ρ × g × h) × base/H × y dy
now integrate it from 0 to 5 height
f = ρ × g 
f = ρ × g 
f = ρ × g × 4/5 × 
now put value ρ = 1000 and g = 9.81
f = ρ × g × 4/5 ×
f = 1000 × 9.81 × 4/5 × (5³/3)
force = 7848 × 41.666667
force = 327000.00 N
hydrostatic force is 327000.00 N
The force is applied to the accelerating object that has a constant mass. Option A is correct.
<h3>
What does Newton's second law of motion state?</h3>
The force applied to the object is the product of its mass and acceleration.
Where,
- force
- mass
- acceleration
From the equation, the force and the acceleration are in a proportional relation. The mass is not changing as given in the question.
Therefore, the force is applied to the accelerating object that has a constant mass.

Answer:
Explanation:
Un electrón tiene una carga negativa de 
y la masa total es igual al producto del número de electrones y esa carga unitaria. El número de electrones se obtiene al dividir la carga total por la carga unitaria. (An electron has a negative charge of and the total mass is equal to the product of the qunatity of electrons and such unit charge. The quantity of electrons is found by diving the total charge by the unit charge):
