We know that an object floats in a fluid if the density of the object is less than the density of the fluid. When some air or water is heated, it expands. That makes its density less than cooler air or water, so it floats in them.
Answer:
the answer is C i didnt mean to put b lol

Answer:
144Ns
Explanation:
Impulse is the product of force and change in time or a measure of the change in momentum. Mathematically, Impulse is given as
J = FΔt
Where
J = Impulse,
F = Force,
Δt = change in time.
Due to the varying force, we know that the impulse varies at different points in the motion. Hence, the Net Impulse will be the addition of the individual impulses, i.e.
J = ΣJᵢ
J = J₁ + J₂ + J₃
J = F₁Δt₁ + F₂Δt₂ + F₃Δt₃
=> J = (24*2) + (24*4) + (0*2)
J = 48 + 96 + 0
J = 144 Ns
In order to find which rational number is between 0 and 1, let's convert them into their decimal form:
Looking at the numbers in their decimal form, we can see that the number between 0 and 1 is one-fourth, therefore the correct option is the second one.
