A light bulb radiates 110 nW of single-frequency sinusoidal electromagnetic waves uniformly in all directions. Calculate the ave
krek1111 [17]

Answer:

The intensity of the light from the bulb would be

3.501 x 10^{-6} W/m^{2}

Explanation:

Given

The Power = 110 n W = 110 x 10^{-9} W

the distance r = 50 mm = 50 /1000 = 0.05 m

The intensity can be obtained with the relationship below;

I = Power/area ......1

The area of the sphere would be used in this case since the bulb is spherical;    A=4πr^{2}

Putting it into equation 1, we have;

I = P/ 4πr^{2}

I =  110 x 10^{-9} / 4 x π x 0.05^{2}

I = 3.501 x 10^{-6} W/m^{2}

Therefore the intensity of the light from the bulb would be

3.501 x 10^{-6} W/m^{2}

Astronaut Rob leaves Earth in a spaceship at a speed of 0.960crelative to an observer onEarth. Rob's destination is a star syste
Slav-nsk [51]

To solve this problem we will use the mathematical definition of the light years in metric terms, from there, through the kinematic equations of motion we will find the distance traveled as a function of the speed in proportion to the elapsed time. Therefore we have to

1Ly =9.4605284*10^{15}m \rightarrow 'Ly'means  Light Year

Then

14.4Ly = 1.36231609*10^{17} m

If we have that

v= \frac{x}{t} \rightarrow t = \frac{x}{t}

Where,

v = Velocity

x = Displacement

t = Time

We have that

t = \frac{1.36231609*10^{17}}{0.96c} \rightarrow c= Speed of light

t = \frac{1.36231609*10^{17}}{0.96(3*10^8)}

t= 454105363 s (\frac{1hour}{3600s})

t= 126140 hours(\frac{1day}{24hours})

t= 5255.85 days(\frac{1 year}{365days})

t = 14.399 years

Therefore will take 14.399 years

A student drops a ball from the top of a 10-meter tall building. The ball leaves the thrower's hand with a zero speed. What is t
Sergio [31]

Answer:

14 m/s

Explanation:

u = 0, h = 10 m, g = 9.8 m/s^2

Use third equation of motion

v^2 = u^2 + 2 g h

Here, v be the velocity of ball as it just strikes with the ground

v^2 = 0 + 2 x 9.8 x 10

v^2 = 196

v = 14 m/s
