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.
Explanation:
(i)
O is the object and I is the image.
The image formed is enlarged and it is erect. So the magnification will be positive (+) and greater than 1.
Refer above image. 1
(ii)
O is the object and I is the image.
The image formed is diminished and erect. So the magnification will be positive (+) and less than1.
Refer above image. 2
(iii)
The image will be formed as the 2F on the other side of the lens and it will be of same of the object.
Answer:
a) The total force is 4659.8 N
b) The gauge pressure is 50764 Pa
Explanation:
Given:
Pressure inside = 0
Patm = pressure outside = 1.013x10⁵Pa
Pressure difference = ΔP = 1.013x10⁵ - 0 = 1.013x10⁵Pa
a) The area is equal:
The force is:
b) The gauge pressure at the bottom is equal:
Where:
ρ = density = 1000 kg/m³
h = 17 ft = 5.18 m
Replacing:
