Answer:

Impulse = Average force x time of contact

Explanation:

Impulsive force is a force which is very large but applied on a body for a very small duration of time.

Impulse is given by the change in momentum of the body.

Impulse = Average force x small time interval

When padding is there, the time interval of contact is large and thus, the force exerted by the body is small.

So, when a person falls on the tile floor, there is no compression and thus, the time of contact is very small and thus the impulsive force is very large, due to  which the body may damage.

So, when a person falls on the carpeted floor, there is a compression and thus, the time of contact is comparatively large and thus the impulsive force is small, due to  which the body may safe.

What is the ratio of thicknesses of crown glass and water that would contain the same number of wavelengths of light?
Serhud [2]

Answer:

the thickness of the glass divided by thickness of water is going to be 1.333 divided by 1.52, which is 0.877. So, the height of this glass, in order to have the same number of wavelengths as in water, the height of the glass will be 0.877 times the height of the water, and so it will be smaller.

In the 1887 experiment by Michelson and Morley, the length of each interferometer arm was 11m. The experimental limit on the mea
Vikentia [17]
For the answer to the question above,
we can get the number of fringes by dividing (delta t) by the period of the light (Which is λ/c). 

fringe = (delta t) / (λ/c) 

We can find (delta t) with the equation: 

delta t = [v^2(L1+L2)]/c^3 

Derivation of this formula can be found in your physics text book. From here we find (delta t): 

600,000^2 x (11+11) / [(3x10^8)^3] = 2.93x10^-13 

2.93x10^-13/ (589x10^-9 / 3x10^8) = 149 fringes 

This answer is correct but may seem large. That is because of your point of reference with the ether which is usually at rest with respect to the sun, making v = 3km/s.

Which statement BEST explains the relationship between mass and weight.A.mass increases, weight is decreases.B.mass increases, w
Dmitry_Shevchenko [17]

B

Weight is caused by the influence of gravity on matter/mass. Weight is given by the formulae;

Weight = Mass * Gravitational acceleration

On earth, the gravitation acceleration is a constant 10m/s2

Therefore the weight will be influenced by mass of the object in a direct relationship.

An increase in mass will cause a proportionate increase in weight.  

Explanation:

Gravity is not constant across the universe with larger celestial bodies have a greater gravitational pull. Therefore an object with the same mass on earth may weigh differently on another celestial body with different gravitational acceleration. An example is the Moon. Due to the fact that the Moon has approximately ¹/3 of earth’s gravitational force, astronauts weight ¹/3 times less on the moon than on earth.
