A crane lifts construction materials from a palette to the top of a building at a constant rate. If the equation y = 42 + 3 models the height of the materials, y, in feet, after 2 seconds of lifting, which statement is true?
The crane lifts the materials at a rate of 3 feet per second, and the initial height of the materials is 0 feet.
The crane lifts the materials at a rate of 3 feet per second, and the initial height of the materials is 4 feet.
The crane lifts the materials at a rate of 4 feet per second, and the initial height of the materials is 0 feet.
The crane lifts the materials at a rate of 4 feet per second, and the initial height of the materials is 3 feet.

answer:

the position of equilibrium will shift to the left.

step-by-step explanation:

the general equation for the dissociation of a weak base is

b + h₂o   ⇌   bh⁺ + oh⁻

according to le châtelier's principle, when a stress is applied to a system at equilibrium, the system will respond in a way that tends to relieve the stress.

if you apply a stress by adding more bh⁺ or oh⁻,   the system will respond by moving in a direction that gets rid of the added ions.

the position of equilibrium will shift to the left, forming more of the undissociated base.

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
