Newtons 1st law of motion states that the object will continue to move at its present speed and direction until an outside force acts upon it.

Explanation:
A lift chart usually refers to a graphical representation that is mainly used in order to improve the drawbacks of a mining model by making a comparison with any random guess, and also helps in determining the changes that occur in terms of lift scores.
It describes the binary classification of the problems associated with the mining activity. This type of chart is commonly used to differentiate the lift scores for a variety of models, and picking the best one out of all.
Thus, the correct answer is option (B).
Answer:

Explanation:
from the ideal gas law we have
PV = mRT


HERE R is gas constant for dry air = 287 J K^{-1} kg^{-1}


We know by ideal gas law



for m_2



WE KNOW
PV = mRT
V, R and T are constant therefore we have
P is directly proportional to mass
