The greenhouse effect is a natural phenomenon that enables life to propagate in Earth. During the day, the Sun provides energy through sunlight. Note that the Sun's energy is obtained from the nuclear fusion of hydrogen to helium. So, sunlight contains radiation at very high temperatures. In order to regulate heat, the atmosphere allows only some of the heat to be absorbed into the surroundings, but blocking the rest and reflecting it back to space. During night time, without the Sun giving energy, greenhouse gases in the atmosphere has 'reserved' heat that is trapped in the atmosphere. So, the greenhouse gases (like water vapor and carbon dioxide) maintains the average temperature of the Earth's atmosphere at around 33°C.

Therefore, the answer is letter B.

In the first-order spectrum, maxima for two different wavelengths are separated on the screen by 3.40 mm . what is the differenc
Strike441 [17]

The solution would be like this for this specific problem:

 

Given:  

diffraction grating slits = 900 slits per centimeter

interference pattern that is observed on a screen from the grating = 2.38m

maxima for two different wavelengths = 3.40mm

 

slit separation .. d = 1/900cm = 1.11^-3cm = 1.111^-5 m <span>

Whenas n = 1, maxima (grating equation) sinθ = λ/d 
Grant distance of each maxima from centre = y .. 
<span>As sinθ ≈ y/D  y/D = λ/d λ = yd / D </span>

∆λ = (λ2 - λ1) = y2.d/D - y1.d/D 
∆λ = (d/D) [y2 -y1] 

<span>∆λ = 1.111^-5m x [3.40^-3m] / 2.38m .. .. ►∆λ = 1.587^-8 m</span></span>

A wire is carrying current vertically downward. What is the direction of the force due to Earth's magnetic field on the wire?
AnnyKZ [126]

Answer:

The direction of the force will be towards the east

Explanation:

From the question we are told that  

    The direction of the  downward

Generally according to Fleming's right-hand rule(

          Thumb -  direction of force

           Middle finger -  direction of current

           Index finger -  direction of the magnetic field

) and the fact that the earth magnetic field acts  from south to north with respect to the four cardinal points then the direction of the  force will be toward the east with respect to the four cardinal point on the earth
