The spectrophotometer measures what property of a solution? Group of answer choices

Physics
1 answer:
Yanka [14]3 years ago
5 0

Answer:

B. The ability of the solute molecules only to absorb the energy of light (photons) at a specific wavelength.

Explanation:

Spectrophotometry is the quantitative measurement of the reflection or transmission properties of a material as a function of wavelength. In case of a solution, both, solute and solvent would absorb the energy on an specific lenghtwave of light if they have a absortion coefficient diffrent of 0. The solvent could absorb energy of light, but it´s not typical, for example water does not absorb light in any lenghtwave. Therefore, for practical uses, we consider that only the solute absorbes, and it case the solvent does, that should be taken into account for the solute concentration calculation.

IceJOKER [234]

Answer:

It is a measure of the electric force per unit charge on a test charge.

Explanation:

The magnitude of the electric field is defined as the force per charge on the test charge.

Since we define electric field as the force per charge, it will have the units of  force divided by the unit of charge. This implies that the SI unit of electric field is given as Newton/Coulomb (N/C).

The parachute on a drag racing car deploys at the end of a run. If the car has a mass of 820 kg and the car is moving 36 m/s, wh
Lelechka [254]

In order to determine the required force to stop the car, proceed as follow:

Calculate the deceleration of the car, by using the following formula:

v^2=v^2_o-2ax

where,

v: final speed = 0m/s (the car stops)

vo: initial speed = 36m/s

x: distance traveled = 980m

a: deceleration of the car= ?

Solve the equation above for a, replace the values of the other parameters and simplify:

\begin{gathered} a=\frac{v^2_o-v^2}{2x} \\ a=\frac{(36\frac{m}{s})^2-(0\frac{m}{s})^2}{2(980m)}=0.66\frac{m}{s^2} \end{gathered}

Next, consider that the formula for the force is:

F=ma

where,

m: mass of the car = 820 kg

a: deceleration of the car = 0.66m/s^2

Replace the previous values and simplify:

F=(820kg)(0.66\frac{m}{s^2})=542.20N

Hence, the required force to stop the car is 542.20N
