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
The electrical resistance of the wire is proportional to its length L and inversely proportional to the square of its diameter,
.
The length of the wire in the problem is changed from 200 inches to 500 inches, so the new length is 2.5 times the initial length:
the diameter of the wire is not changed, so the new electrical resistance must be 2.5 times the original value:
When the moon is waxing it means that the sunlit fraction we can see from earth is getting larger. when it is wanning, the sunlit fraction is getting smaller and even as the phases of the moon change the total amount of sunlight the moon gets remains the same. half the moon is always in sunlight just as half the earth is always in sunlight. but because the period of rotation for the moon is the same as its period of revolution, on earth we always see the same side of the moon. If you lived on the far side of the moon, you would see the sun for half of each lunar day, but you would never see the earth.
Answer:
answer 1 is A, Answer 2 is A, Answer 3 is c
Answer:
F = 29.9 N
Explanation:
It is given that, The Sun exerts a gravitational force of 29.9 N on a rock that's located in a river bed here on Earth. We need to find the gravitational force the rock exert on the Sun. It is a case of Newton's third law of motion which states that the force acting from one object to another is equal to the force acing from second object to the first object and the two forces must be in opposite direction. Hence, the gravitational force the rock exert on the Sun is same i.e. 29.9 N.
