To solve this problem we will define the given angular velocity, in terms of international units, we will subsequently use the definition of radial acceleration, defined as the product between the square of the angular velocity and the radius. Finally we will convert the units to gravitational terms or units G.
PART A) Our values in SI are,
Radial acceleration can be described as
PART A) If we have that 1g is equivalent to performing the conversion we have to
Answer:
Refractive index, n = 2.419
Explanation:
It is given that,
Speed of light in the medium,
Speed of light in the vacuum,
Let n is the index of refraction for a medium. We know that the refractive index for any medium is equal to the ratio of speed of light in vacuum to the speed of light in medium. It can be written as :
n = 2.419
So, the index of refraction for a medium is 2.419. Hence, this is the required solution.
Initially there were 10 bulbs of 60 Watt power
So total power of all bulbs = 60 * 10 = 600 W
now each bulb used for 4 hours daily
so total energy consumed daily
now we have total power consumed in 1 year
cost of electricity = 10 cents/ kWh
so total cost of energy for one year
Now if all 60 Watt bulbs are replaced by 30 Watt bulbs
So total power of all bulbs = 30 * 10 = 300 W
now each bulb used for 4 hours daily
so total energy consumed daily
now we have total power consumed in 1 year
cost of electricity = 10 cents/ kWh
so total cost of energy for one year
total money saved in 1 year
1950 g This is the answer due to the kilograms of lead being distributed
