Lasers can be constructed that produce an extremely high intensity electromagnetic wave for a brief time—called pulsed lasers. T
MAVERICK [17]

Explanation:

It is given that,

Maximum electric field, E=10^{11}\ V/m

Time taken, t=1\ ns=10^{-9}\ s

(a) Maximum magnetic field, B=\dfrac{E}{c}

B=\dfrac{10^{11}\ V/m}{3\times 10^8\ m/s}

B = 333.33 T

(b) Intensity of beam, I=\dfrac{E^2}{2\mu_o c}

I=\dfrac{(10^{11})^2}{2\times 4\pi \times 10^{-7}\times 3\times 10^8}

I=1.32\times 10^{19}\ W/m^2

(c) Energy delivered by the pulse, E=I\times A\times t

E=1.32\times 10^{19}\times 10^{-6}\times 10^{-9}

E = 13200 J

Hence, this is the required solution.

zloy xaker [14]

Answer:

0.75Hz

Explanation:

Given parameters:

Speed of the wave = 3m/s

Wavelength  = 4m

Unknown:

Frequency of the wave  = ?

Solution:

The speed of a wave is given by the expression below:

     Speed  = frequency x wavelength

  Frequency  = \frac{Speed }{Wavelength}   = \frac{3}{4}    = 0.75Hz

Explain how the theory of the Sun’s dynamo results in an average 22-year solar activity cycle. Include the location and mechanis
horrorfan [7]

Answer:

Explanation:

Sun's dynamo means the process that produce Sun's magnetic field.

The mechanism inside a Sun acts like a generator that produces electric current and magnetic field.

Magnetic field with in the Sun are extended out and around. Magnetic field of lines get twisted due to rotation of Sun.

The material that flows inside the Sun plays an important role in Sun's dynamo. At surface the flow rate is about 20 m/s but as it moves towards equator, it becomes way too slow taking about 11 years of time.

Due to the this magnetic field, several sun spots are formed on the surface.

The number of sunspots keep on changing from minimum to maximum number resulting into change in the magnetic pole. In each cycle polarity get reversed hence the overall magnetic cycle has an interval of 22 years.

Min is asked to balance the equation below.
Minchanka [31]
It is incorrect, because the identity of the original product has changed. Ca3(OH)2 does not exist! It is no longer calcium hydroxide. To balance an equation, you must manipulate the coefficients, a.k.a. the big numbers that go before reactants or products. Subscripts, the little numbers inside the reactants or products, cannot be changed without completely changing the substance.
