Germans paid 1.65 euros per liter of gasoline
American prices were $3.90 per gallon and for one liter = $3.90
/ 4.55 = $0.86
One US dollar = 0.76 Euros
If Germans paid 1.65 euros for 1 liter, they will pay for 1
gallon = 1.65 euros x 4.55 liters = 7.51
Price of one gallon Germans paid in euros = 7.51 euros
As, 1 Us dollar=0.76 euros from this we get 1 euro = 1.31
dollars
So, price of one gallon Germans paid in dollars = 7.51 x
1.31 = $9.84
American gasoline have cost in euros per liter = 0.86 x 0.76
= 0.65 euros
The wave length becomes shorter and the pitch becomes higher
Answer:
Third Option
Explanation:
If we have a vector A = ax + by we know that by definition
cA = cax + cby
Where c is a constant.
In this case we have two vectors
You may notice that vector B has an opposite direction to vector A.
You may also notice that | Ax | is the double of | Bx | and | Ay | is double of |By |
That is to say
So the equation that relates to vectors A and B is:
.
You can verify this relationship by performing the operation
Answer:
117.7 N
Explanation:
F = ma
= 12 kg * 9.81 m/s^2 = 117.7 N ( on Earth)
Validity concludes the whole experimental values and concepts which makes that whether the results which are obtained meet all of the requirements of the scientific research method.
On which factors the validity of an experiment depends?
There are five components which are used in experiment: observations, questions, hypothesis, methods and results. The scientific method procedure is not only ensures that the same experiment can be repeated by other researchers, but this experiment is accepted. For example, there must have been arrange in a random way of the sample groups and proper work and care shows and the experiment is succeed.
So we can conclude that: Validity concludes the whole experimental values and concepts which makes that whether the results which are obtained meet all of the requirements of the scientific research method.
