We will use the percentage difference formula and so:
By plugging in our values we obtain:
And 0.142349 converted to percentage is :
Therefore, there was a population increase of 14.2349% from 2000 to 2015 in the US.
Answer: hydroelectric dams
Explanation: Enormous energy is stored in water held back by hydroelectric dams. The energy is transformed into (a form of kinetic energy) as it falls across the dam. The falling water strikes the blades of a turbine and makes them spin, and the then turns the shaft of a generator.
As the stan moves 0.94 s before with an acceleration 4.12 m/s^2
so the distance moved by it
![d = \frac{1}{2}at^2[tex]d = \frac{1}{2}*4.12*0.94^2](https://tex.z-dn.net/?f=d%20%3D%20%5Cfrac%7B1%7D%7B2%7Dat%5E2%3C%2Fp%3E%3Cp%3E%5Btex%5Dd%20%3D%20%5Cfrac%7B1%7D%7B2%7D%2A4.12%2A0.94%5E2)
speed gained by the car is given as
now the relative speed of them is given as
relative acceleration is given as
now the distance between them is to be covered
by solving above equation we have
so it will overtake after 6.64 s
Answer:
B. Value you have recorded during your experiment.
Explanation:
In the observation section, those data is present which is collected during an experiment. Measurement of each key should be reported carefully. Data is usually present in the form of table, graph and figures.
This data can be represented in the tabular form because it is the best method to represent any data.
Therefore, in the observation section of lab report observer usually find the values which are recorded during an experiment.
