Answer:
Explained
Explanation:
Thickness coating= t
wavelength of light λ = 500 nm
2 t =(m+0.5)λ
Here m = 0
t= λ/4
= 500/4 nm
= 125 nm
= 125×10^(-9) m
Answer:
E = 600 J
Explanation:
The power is
P = W / t = E / t
E = P t
The electrical power is
P = V I
We substitute
E = V I t
Let's calculate
E = 12 50 1
E = 600 J
This is the energy stored in the battery
Answer:
Density
Explanation:
Density is a property that will allow for a possible identification of a material. Different materials have different densities. The unit for density is g/cm^3
The child at 5 years old would weight: 60 lb (27.16 kg) If he continues gaining weight a that rate
To solve this problem we will use a rule of three with the problem information:
3 years-------- 36 lb child's weight
5 years -------- x
Applying the rule of three we get:
x = ( 5 years * 36 lb child's weigh) / 3 years
x = 60 lb
By converting the weight units from lb to kg we have:
x = 60 lb * 16.3 kg/36 lb
x = 27.16 kg
<h3>What is rule of three?</h3>
It describes the proportionality of 3 known data and an unknown data. When you have more than 3 known facts that are involved in the proportionality, it is known as a compound rule. The rule of three is also known as a direct proportions.
