Speed of light in vacuum = 2.998 x 10^8 m/s
1m = 1/1000 km and 1s = 1/3600 hr
Speed of light in vacuum = (2.998 x 10^8 x (1/1000)
km) / (1/3600) hr
Speed of light in vacuum = 10.792 x 10^8 km/hr
Now
1km = 0.6213 mi
1hr = 60min
As Speed of light in vacuum = 10.792 x 10^8 km/hr
Speed of light in vacuum = 10.792 x 10^8 x (0.6213mi)
/ 60min
Speed of light in vacuum = 0.1117 x 10^8 mi/min
<span>Speed of light in vacuum = 11.17 x 10^6 mi/min</span>
We know that
AB = 10x + 4
BC = 4x - 3
AC = 12x + 16
We need to find x, AB and BC.
The solution of the question is based on the assumption that the point A, B and C are col-linear, i.e. they lie on the same line, and B lies between A and C
⇒ AB + BC = AC
Substituting the values of AB, BC and AC in terms of x in the above equation, and solving the linear equation.
⇒ 10x+4 + 4x-3 = 12x+16
⇒ 14x+1 = 12x+16
⇒ 2x = 15
⇒ x = 7.5
Substituting the value of x in 10x+4 to determine the length of AB
AB = 10x+4
⇒ AB = (10×7.5)+4
⇒ AB = 75+4
⇒ AB = 79
Hence, AB is 79 units
Substituting the value of x in 4x-3 to determine the length of BC
BC = 4x-3
⇒ BC = (4×7.5)-3
⇒ BC = 30-3
⇒ BC = 27
Hence, BC is 27 units
Answer:
Step-by-step explanation:
We know that,
where
r = number of successful trials = 122,
n = 328
p = proportion
From probability distribution we also know that,
for a 99% confidence level = 2.576
Marginal error will be,
Putting the values,
So the interval will be,
Answer:
The substance will not be in liquid state in range -273.15
(absolute zero) to -47.42
and the temperature above 364.76
Explanation:
The Substance will be in solid state in at the temperature below its melting point and it will be is gaseous state at the temperature above its boiling point. So it will be liquid between melting and boiling point.
Step-by-step explanation:
