B false. This is really stereotypical and isn't always the case, but people with high self esteem think they're amazing, they think they're the best of the best etc... Because of this, they won't take the blame for their own actions, and thus will try to blame it on other people.
Nitrites are 307880 115 and control is 30 8112 1250
Let X be nitrate group and let Y be a control group.
If ∪X-∪Y∠0 then we can say that nitrates decrease the number of amino acids which is taken.
Hypothesis test.
H0:∪X-∪Y=0Vs. Where H1:∪X-∪Y∠0.
Sample for X = 7880 and Y = 8112 and Sx∧2=variance sample for X = 1115∧2 = 1243225 and Sy∧2 = variancesample for Y= 1250∧2 = 1562500. The size of the sample = 30 for both cases.
Test statistics is Z =((7880-8112)-0)/squareroot (1243225/30+1562500/30) = 0.758623)
Value of P = P(Z∠z)
=P(Z∠-0.758623).
Since P-value is greater than the importance of 0.02, we can not reject the null hypothesis. The conclusion is that ∪x-∪y =0 a good example is nitrates does not decrease the number of amino acid which is taken.
Answer:
The smaller object will move at 30 m/s
Explanation:
From the principle of conservation of linear momentum,
Momentum of objects before collision = momentum of objects after collision.
![m_{1}v_{1} + m_{2}v_{2}=m_{1}v_{3}+m_{2}v_{4}](https://tex.z-dn.net/?f=m_%7B1%7Dv_%7B1%7D%20%2B%20m_%7B2%7Dv_%7B2%7D%3Dm_%7B1%7Dv_%7B3%7D%2Bm_%7B2%7Dv_%7B4%7D)
where
are the masses and velocities of the objects 1 and 2 respectively before collision.
![40\times 20 + 20\times 10 = 40\times 10 + 20\times v_{4}](https://tex.z-dn.net/?f=40%5Ctimes%2020%20%2B%2020%5Ctimes%2010%20%3D%2040%5Ctimes%2010%20%2B%2020%5Ctimes%20v_%7B4%7D)
![1000= 400 + 20v_{4}](https://tex.z-dn.net/?f=1000%3D%20400%20%2B%2020v_%7B4%7D)
![v_{4}=30m/s](https://tex.z-dn.net/?f=v_%7B4%7D%3D30m%2Fs)
Hence, the object will move at 30 m/s
