Please help 10 points Carmen setup a gas law calculation as shown:
Givens in the
problem:
V1= V2. 300 = V2
T1 = T2 33. = 55

Her classmate setup the same problem but solved for a different answer.
Why do the students have different answers?

A. Carmen did not substitute the correct numbers.

B. Carmen used the wrong gas law equation.

C. Carmen used Celsius temperature instead of Kelvin temperature.

D. Carmen divided two of the numbers then multiplied that answer by the third number.

Look at the spectrums of a star moving towards earth and a motionless star. which of these is a correct inference that can be draw from the observation of the two spectrums? (2 points) the spectrum of a motionless star is difficult to be viewed separately using oridinary telescopes. the spectrum of a motionless star is identical to the spectrum of a star which moves towards earth. the spectrum of a star shifts towards the red region when the star moves towards earth. the spectrum of a star shifts towards the blue region when the star moves towards earth.
