The power dissipated in the 6 ohms resistor is determined as 24 W and the power dissipated in the 3 ohms resistor is determined as 48 W.

<h3>Power dissipated in the resistors</h3>

The power dissipated in the resistors is calculated as follows;

P = IV

where;

  • I is current
  • V is voltage = 12 V

From Ohm's law, V = IR, ⇒ I = V/R

P = V²/R

where;

  • R is resistance of the circuit
<h3>Power dissipated in 6 ohms </h3>

P = (12)²/6

P = 24 W

<h3>Power dissipated in 3 ohms</h3>

P = (12)²/3

P = 48 W

Suppose that light from a laser with wavelength 633 nm is incident on a thin slit of width 0.500 mm. If the diffracted light pro
coldgirl [10]

Explanation:

It is given that,

Wavelength, \lambda=633\ nm=633\times 10^{-9}\ m

Slit width, a=0.5\ mm=0.0005\ m

Order, m = 2

If the diffracted light projects onto a screen at distance 1.50 m, L = 1.5 m

For the diffraction of light,

y=\dfrac{m\lambda L}{a}

y=\dfrac{2\times 633\times 10^{-9}\times 1.5}{0.0005}

y = 0.0037 m

So, the distance from the center of the diffraction pattern to the dark band is 0.0037 meters. Hence, this is the required solution.

A ball droped from a building. How fast is it traveling after falling 3.55s
algol [13]

Answer:

d = 61.75 m

Explanation:

Given that,

A ball droped from a building.

We need to find how fast is it traveling after falling 3.55 s.

As it is dropped, its initial velocity is equal to 0.

Let d is the distance it covers after falling 3.55 s.

We can use second equation of motion to find d.

d=ut+\dfrac{1}{2}at^2

Here, u = 0 and a =g

d=\dfrac{1}{2}gt^2\\\\d=\dfrac{1}{2}\times 9.8\times (3.55)^2\\\\d=61.75\ m

So, it will cover 61.75 m after falling 3.55 seconds.

Answer:

  D. 3.0 × 10^-6 m

Explanation:

Wavelength is found by dividing the speed of light by the frequency:

  λ = c/f = (3·10^8 m/s)/(1.0·10^14 Hz) = 3.0·10^-6 m

A pulsar is a rapidly rotating neutron star that emits a radio beam the way a lighthouse emits a light beam. We receive a radio
Angelina_Jolie [31]

a) -0.259 rad/s/y

b) 1732.8 years

c) 0.0069698 s

Explanation:

a)

The angular acceleration of a rotating object is equal to the rate of change of angular velocity of the object.

Mathematically, it is given by

\alpha=\frac{\Delta \omega}{\Delta t}

where

\Delta \omega is the change in angular velocity

\Delta t is the time elapsed

The angular velocity can be written as

\omega=\frac{2\pi}{T}

where T is the period of rotation of the object.

Therefore, the change in angular velocity can be written as

\Delta \omega = \frac{2\pi}{T'}-\frac{2\pi}{T}=2\pi (\frac{1}{T'}-\frac{1}{T})

In this problem:

T = 0.0140 s is the initial period of the pulsar

The period increases at a rate of 8.09 x 10-6 s/y, so after 1 year, the new period is

T'=T+8.09\cdot 10^{-6} =0.01400809 s

Therefore, the change in angular velocity after 1 year is

\Delta \omega =2\pi (\frac{1}{0.01400809}-\frac{1}{0.0140})=-0.259 rad/s

So, the angular acceleration of the pulsar is

\alpha = \frac{-0.259 rad/s}{1 y}=-0.259 rad/s/y

b)

To solve this part, we can use the following equation of motion:

\omega'=\omega + \alpha t

where

\omega' is the final angular velocity

\omega is the initial angular velocity

\alpha is the angular acceleration

t is the time

For the pulsar in this problem:

\omega=\frac{2\pi}{T}=\frac{2\pi}{0.0140}=448.8 rad/s is the initial angular velocity

\omega'=0, since we want to find the time t after which the pulsar stops rotating

\alpha = -0.259 rad/s/y is the angular acceleration

Therefore solving for t, we find the time after which the pulsar stops rotating:

t'=-\frac{\omega}{\alpha}=-\frac{448.8}{-0.259}=1732.8 y

c)

As we said in the previous part of the problem, the rate of change of the period of the pulsar is

\frac{\Delta T}{\Delta t}=8.09\cdot 10^{-6} s/y

which means that the period of the pulsar increases by

\Delta T=8.09\cdot 10^{-6} s

For every year:

\Delta t=1 y

From part A), we also know that the current period of the pulsar is

T = 0.0140 s

The current period is related to the initial period of the supernova by

T=T_0+\frac{\Delta T}{\Delta t}\Delta t

where T_0 is the original period and

\Delta t=869 y

is the time that has passed; solving for T0,

T_0=T-\frac{\Delta T}{\Delta t}\Delta t=0.0140 - (8.09\cdot 10^{-6})(869)=0.0069698 s
