Acylinder is submerged in water as illustrated in the diagram. if the area of the top and the bottom of the cylinder is the same, which of the following statements is true?
a) buoyant force = (force b - force c)
b) buoyant force = (force d - force a)
c) buoyant force = (force b - force a)
d) buoyant force = (force c - force b)
(tap the picture to see the whole thing)

The correct answer is option B.

Explanation:

Buoyant forces : It is an upthrust or an upward force exerted by the fluids on the weight of an object immersed in it.It always act opposite and perpendicular to the weight of the object.

This force is always larger on the bottom of an object than the force on top of an object.

In the given diagram. force A is pushing object downwards and force D is pushing the object upwards.

D > A (force at bottom> force at top)

So, the buoyant force of the cylinder is given by:

= Force D - Force A.

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
