Explain what happens with light causing you to see colored opaque objects

algol13

answer:

an opaque object is one that doesn't let light pass through it. instead, it reflects or absorbs the light that strikes it.

explanation:

in this case, we see the material because of the transmitted light. therefore, the wavelength of the transmitted light determines the color that the object appears.

good luck :)

i hope this helps

have a nice day !!

A car is traveling in uniform circular motion on a section of flat roadway whose radius is . The road is slippery, and the car i

Alona [7]

Answer:

The smallest radius will be four (4) times the initial radius

Explanation:

The car maintains a constant angular speed. According to Newton's Second Law F = m a

1. $F_{r}=m*A_{n}$

2. $A_{n}=\frac{v^2}{R_{p}}$

Replacing 2 in 1

3. $F_{r}=m*\frac{v^2}{R_{p}}$

Where:

Fr= Frictional force

Rp= Initial Radius

An= Centripetal Acceleration

M= Mass

V= Velocity

Also we have that:

4. $F_{r}=\mu *W=\mu*m*g$

μ= Coefficient of friction between the car and the surface

M= Mass

W= Weight

G= Gravity

r is cleared from equation 3

5. $R_{p}=m*\frac{v^2}{F_{r}}$

Replacing 4 in 5

6. $R_{p}=m*\frac{v^2}{\mu*m*g}$

Simplifying

7. $R_{p}=\frac{v^2}{\mu*g}$

Now we have a new velocity equal to twice the initial velocity, We replace it by 2v in equation 7

8. $R_{n}=\frac{(2v)^2}{\mu*g}$

Computing

9. $R_{n}=\frac{4v^2}{\mu*g}$

Replacing 5 in 9

$R_{n}=4*R_{p}$

A sodium vapor lamp omit waves with the frequency of 5.26x10^14 Hz. What is the wavelength of light?

koban [17]

Answer:

$\lambda=5.70\times 10^{-7}\ m$

Explanation:

The frequency of a sodium vapor lamp, $f=5.26\times 10^{14}\ Hz$

We need to find the wavelength of light. The relation between wavelength, frequency and speed of light is given by :

$c=f\lambda\\\\\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^8}{5.26\times 10^{14}}\\\\\lambda=5.70\times 10^{-7}\ m$

So, the wavelength of light is equal to $5.70\times 10^{-7}\ m$ .
