Answer:
root-mean-sqaure = 2.77 m/s
average = 2.72 m/s
The root-mean-square is always the largest because it takes account of the variance of the spread of the data. The increase is related to the fact that the data varies to sample.
Explanation:
The rootmean-square (R) is the square root of the squares of the valeus divided by the number of the datas.


R = √(46.03)/6
R = 2.77 m/s
The average speed is the sum of the speeds divided by the number of datas:

A = 16.3/6
A = 2.72 m/s
Answer: voltage drops in each resistor ΔU= RI
Explanation: if lamps or other resistor which cause load are in series in
Electric circuit, current I passing circuit is same. Voltage decreases
In every resistor
<em>Answer:</em>
<em>Ether:</em>
Ether are organic compounds that contain ether functional group , in which oxygen atom is connected with two alkyl or aryl group.
They have general formula as follow
- R---O---R or R'---O----R or R'---O---R'
while R = Alkyl
R' = Aryl
