Ans: Dilute the solution

Explanation:
To decrease the over-saturation, dilute the solution. Dilution is the process of decreasing the solute's concentration in the solution. It is usually done by mixing with more solvent. In other words, to dilute a solution means to add more solvent without the addition of more solute.

The height of an object dropped from the top of a 64-foot building is given by h(t)=-16t^2+64. How long will it take the object

mojhsa [17]

Answer:

1.86 s

Explanation:

Given the expression

h(t) = -16t²+ 64...................... Equation 1

Where h = height of the object, t = time it will take the object to hit the ground.

Given: h = 64 foot.

We have to concert from foot to meters

If 1 foot = 0.3048 meters

Then, 64 foot = 0.3048×64 = 19.51 meters.

We substitute the value of h into equation

119.51 = -16t²+64

-16t² = 199.51-64

-16t² = 55.51

t² = 55.51/-16

t² = 3.469

t = √3.469

t = 1.86 s.

Hence it will take the object 1.86 s to hit the ground.

How is the wavelength of a longitudinal wave determined?

Tju [1.3M]

Before answering the question, first we have to understand a longitudinal wave.

A longitudinal wave is a type of mechanical wave in which the direction of wave propagation is parallel to the particle vibration of the medium.

In this type of wave, there will be compressions and rarefactions. Compressions are the high pressure regions where the particles of the medium are very close to each other. The rarefactions are the low pressure regions of a longitudinal wave where the particles are not so close to each other.

Hence, a longitudinal wave is a series of compressions and rarefactions.

The wavelength of a longitudinal wave is defined as the distance between two successive compressions or rarefactions.

Hence, the correct answer to the question is C) by measuring the distance between adjacent rarefactions.

A nichrome wire and an aluminum wire, each with the same initial resistance, have the same change in resistance when heated sepa

Svetach [21]

Answer:

The ratio of temperature change of nichrome wire to the temperature change of aluminum wire is found to be 9.75

Explanation:

The change in resistances and initial resistances of the wires are:

Change in Resistance of Nichrome Wire = ΔR₁

Change in Resistance of Aluminum Wire = ΔR₂

Initial Resistance of Nichrome Wire = R₁

Initial Resistance of Aluminum Wire = R₂

Also, it is given that the change in resistance and initial resistance of both wires is equal. Therefore,

ΔR₁ = ΔR₂ ---------- eqn (1)

R₁ = R₂ ---------- eqn (2)

The change in Resistance due to temperature is given by formula:

ΔR = R α ΔT

Therefore, eqn (1) becomes:

R₁ α₁ ΔT₁ = R₂ α₂ ΔT₂

using eqn (2):

α₁ ΔT₁ = α₂ ΔT₂

ΔT₁/ΔT₂ = α₂/α₁

where,

α₁ = Temperature coefficient of resistance of nichrome = 0.4 x 10⁻³ °C⁻¹

α₂ = Temperature coefficient of resistance of aluminum = 3.9 x 10⁻³ °C⁻¹

Therefore,

ΔT₁/ΔT₂ = (3.9 x 10⁻³ °C⁻¹)/(0.4 x 10⁻³ °C⁻¹)

ΔT₁/ΔT₂ = 9.75
