Answer:
180Watts
Explanation:
Power = Force * distance/Time
Given
Force = 500N
Distance = 18m
Time t = 50secs
Substitute into the formula
Power = 500*18/50
Power = 10 * 18
Power = 180Watts
Hence her power output vertically is is 180Watts
Answer:
Force is measured in "Newton's" - kg-m/s^2
F = M a = kg * m/s^2
This in the kgm-m systen - in the gram-cm system you have
F = dynes = gram-cm/s^2
Since 1 gm = .001 kg and 1 cm = .01 m
1 dyne = 1.0^-5 newtons
How did you take a picture?
Answer:
So then we will have at least 75% of the data within two deviations from the mean .
So then the interval would be (97.14, 99.5)
Explanation:
Previous concepts
Chebyshev’s rule is appropriate for any distribution. "Chebyshev’s inequality applies to all distributions, regardless of shape". And is useful since provides a "minimum percentage of the observations that lies within k standard deviations of the mean. "
If k = 2, at least 3/4 of the measurements lie within 2 standard deviations to within the mean.
And the general formula is (1-1/k^2) represent the fraction of the data within the mean .
Solution to the problem
For this case we want to find the percentage of data that would be at least within two deviations from the mean so for this case the value of k =2 and if we replace we got:
So then we will have at least 75% of the data within two deviations from the mean .
For the other part we have the mean and deviation provided the interval would be:
So then the interval would be (97.14, 99.5)
Kinetic energy. It decreases as you move further away from the nucleus. Electrons further away from the nucleus are held more weakly by the nucleus and so can be removed by spending less energy which is why these electrons will have higher energy
