Answer:
Explanation:
a) A coin has two sides, therefore the total outcome possible when a coin is tossed is 2 i.e Head (H) and Tail (T)
outcome of two coins will be 4 i.e 2^2
Outcome of three coins will be 8 i.e 2^3 and so on. Since its following a trend, the outcome when 'n' coins is tossed will be 2^n.
Using the general formula, the possible outcome when a coin is tossed 13 times will be "2^13"
b)
Answer:
The first
Explanation:
Cause it will continue in motion till another force is applied
A system that can be affected by the outside environment, by an exchange of matter or energy is an open physical system .
Answer:
n = 1.4266
Explanation:
Given that:
refractive index of crystalline slab n = 1.665
let refractive index of fluid is n.
angle of incidence θ₁ = 37.0°
Critical angle
According to Snell's law of refraction:
At point P ;
Therefore:
Then maximum value of refractive index n of the fluid is:
n = 1.4266
