Answer:
It is true that Smaller the surface area greater the gravitational force and vice versa
Explanation:
The gravitational force depends on the distance between the two objects
F=GMm/r2
where G = gravitational constant
M = mass of one object
m = mass of second object
r is the distance between the two objects
Gravitational force is inversely proportional to the square of the distance between two objects. Hence, it can be said the Gravitational force is inversely proportional to the area and hence as the area increases gravitational force will decrease or vice versa
Answer
given,
wavelength of laser light = 632.8 nm
assuming that aperture of lens be equal to dia = 1 mm
now,
When laser light passes through aperture diffraction of light takes place
The first diffraction minima occurs at

where a is the width of aperture
λ is the wavelength of light
p is the angle



p = 0.0363° angle of the first dark ring
Answer:
Newtons first law
Explanation:
Objects stay at rest until a force acts on it causing it to move from its resting position
For constant fore the impulse could be increased by increasing the time for the force.
Answer:
the inner core if I believe. I apologize if I am incorrect
