user100 [1]

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

The battery on your car has a rating stated in ampere-hours that permits you to estimatethelengthoftimeafullychargedbatterycould
KengaRu [80]

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

If the child is gaining weight at an expected rate, a child who weighs 36 lb (16.3 kg) at 3 years of age would weigh what amount
algol [13]

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.
