Answer:
the last one, the third one, and the first one.
Answer:
The diameter of the hose is 0.326 mm.
Explanation:
Given that,
Speed of car = 28 miles/galllon
We need to calculate the radius
The rate of flow of fluid is from the equation of continuity

Where, A = area of cross sectional

We know that,
The velocity is the ratio of displacement of gas per unit time.


Put the value into the formula



We need to calculate the diameter of the hose

Put the value of r


Hence, The diameter of the hose is 0.326 mm.
An Astronomer who made a list of 100 nebulae and galaxies that could
be mistaken for comets was Charles Messer's.
Charles Messier's was a very famous scientist in the field of Astronomy.
His research in appearance of Great comet filled spark to his passion
of Astronomy. On January 21, 1759 he put his thought of wrong
calculation of Delisle's and he described a faint glow resembling comet
had been seen earlier. Then after, he discovered great comet near
sword of Orion.
There are various tales of Charles Messiers which put him forward
towards his love of Astronomy.

To solve this problem we will apply the concepts related to resistance as a function of temperature, product of the relationship between the squared voltage and the power. Mathematically this is,

Here,
R = Resistance (At function of temperature)
v = Voltage
P = Power
Then we have,
R at 140°C (7 times room temperature),


The relationship between normal temperature and increased temperature would then be given by,




Therefore the correct value of the group of answer is 1350
