Explanation:
The gravitational force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. Mathematically, it is given by :
...............(1)
Where m₁ and m₂ are masses
r is the distance between them
It is clear from equation (1) that :
1. The gravitational force between two objects is inversely proportional to the square of the distance between the two objects.
2. The gravitational force between two objects is proportional to the product of the masses of the two objects.
Hence, this is the required solution.
From what I have been told, the four basic forces regarding physics are the strong or powerful force, a gravitational force, an electromagnetic force, and a weak force. The strong force binds nuclei. Weak forces take care of nuclear decay. Electromagnetic forces exists when two or more objects have an electric charge like a magnet or positive and negative, negative and positive And gravitational forces is just gravity. What holds us down.
Answer:
0.68 m
Explanation:
We know that the speed of sound in air is a product of frequency and wavelength. Taking speed of sound in air as 340 m/s
V=frequency*wavelength
Then wavelength is given by 350/500=0.68 m
Therefore, to repeat constructive interference at the listener's ear, a distance of 0.68 m is needed
Answer:
11.2m³
Explanation:
Applying Archimedes principle we have it that
Weight of submarine+ weight of tank+ weight of compound air =uptrust
So
(40000+2000+37V) x9.8= (30+V) 1030 x 9.8
38910= 993V
V= 11.2m³
The answer is potential for this question
