If the statistical analysis shows that the significance level is below the cut off value they have set (either 0.05 or 0.01) they reject the null hypothesis and accept the alternative hypothesis
2.7 m/s2 average acceleration of a northbound subway train
Answer:
No .
Explanation:
The vapor pressure of water at room temperature is .0313 atom or 3.13 kPa.
To make a liquid boil, its vapor pressure must be equal to pressure around it.
So pump must create pressure of 3.13 k Pa or less to make water attain its stage of boiling at room temperature. As the motor can not produce pressure lesser than 15 k Pa , pump will not be able to make water boil at room temperature.
Centripetal force is F=mv^2/r. So F=50(1.2^2)/16=4.5J
