The velocity of Ned as measured by Pam is the interpretation of v.
Answer: Option D
<u>Explanation:</u>
According to question, we know that this is an issue depending on the logical and translation of the factors. From the measured information taken what is gathered by the two people is communicated and we have given as:
The Ned reference framework : (x, t)
The Pam reference framework :
From the reference framework, we realize that ν is the speed of Pam (the other reference framework) as estimation by Ned.
At that point, is the speed of Ned (from the other arrangement of the reference) as estimation by Pam.
Answer: The correct answer is A. Breed a cow that produces large quantities of milk with a bull that comes from a line of cattle with long lifespans.
Explanation: This answer makes the most since and it shows the use of artificial selection. Artificial selection is when humans breed selectively to develop certain traits they are looking for or want in an animal. (I took the test and this was the correct answer.)
Have a nice day! :)
Answer:
Explanation:
From the question we are told that
Pressurized air pressure is
Atmospheric pressure is
Initial acceleration of the water rocket is
Acceleration of the water rocket is
Mass of water is
Generally total mass is given mathematically given as
Generally the tension on the rocket is given mathematically given as
T is also
Therefore
therefore diameter of nozzle is mathematically given as
Answer:
The total initial volume of air in the tire is 800 cm³
Explanation:
Given;
volume of air in the bicycle pump, V₁ = 200 cm³
volume of the tire, V₂ = 800 cm³
The total initial volume of air in the tire is 800 cm³ and when the pump is pushed in, the total volume of air in the tire becomes 200 cm³. This occurs because the new air pumped into the tire through the bicycle pump compresses the air that was previously in the tire and raises the pressure of the tire that was initially flat.
From Boyle's law, a decrease in volume causes an increase in pressure.
