Ya the equation F=MA
So you do mass x acceleration
10 x 2 = 20
Force is measured in Newtons which has a unit of N
So the answer is = 20N
Hope that is helpful
Answer:
0.25 N
Explanation:
The density of the ball (
) = 0.0839 g/cm³ = 83.9 kg/m³
The density of water (
) = 1000 kg/m³
diameter = 3.77 cm = 0.0377 m
radius of ball = 0.0377/2 = 0.01885 m
The volume (V) = 
Let us assume the acceleration due to gravity (g) = 9.8 m/s²
Hence:
The force is required to hold it completely submerged under water (F) is:

F = 0.25 N
Answer:
the max is 2,500 or less

Answer:
We can use optical fibers.
Explanation:
The optical fibers are the optical devices which is based on the total internal reflection.
The optical fiber has two layers, one is called core and the other is called cladding.
The refractive index of core is more than the cladding.
As a ray of light falls on the core at more than the critical angle for that pair of media(core and cladding), it suffers the total internal reflection at the interface.
