n velocity of objects that are 1.9 megaparsecs from Earth? (c) Can we use the regression equation to estimate the mean velocity of objects that are 2.6 megaparsecs from earth? Yes, we can estimate the mean velocity of objects that are any distance from earth. No, because 2.6 is outside the range of the data values for the explanatory variable. (d) If you were to test the claim that there is a positive linear relationship between the explanatory and response variable, what would your null and alternative hypotheses be? H0: b1 =0 and Ha: b1 < 0 H0: b1 = 0 and Ha: b1 ≠ 0 H0: b1 =0 and Ha: b1 > 0 H0: β1 =0 and Ha: β1 < 0 H0: β1 = 0 and Ha: β1 ≠ 0 H0: β1 =0 and Ha: β1 > 0

Answer:
45000 K .
Explanation:
Given :
A liter of a gas weigh 2 gram at 300 kelvin temperature and 1 atm pressure
We need to find the temperature in which 1 litre of the same gas weigh 1 gram
in pressure 75 atm.
We know, by ideal gas equation :
Here , n is no of moles ,
Putting initial and final values and dividing them :
Hence , this is the required solution.

Given data
Mass of disk M=2.0 kg
Diameter of disk d=20 cm=0.20 m
To Find
(a) Moment of inertia through the center of disk
(b) Moment of inertia through the edge of disk
Solution
For (a) Moment of inertia through the center of disk
Using the equation of moment of Inertia
For (b) Moment of inertia through the edge of disk
We can apply parallel axis theorem for calculating moment of inertia
