If the earth's rotation axis was tilted by 45 degrees instead of 23.5 degrees, how would that affect the climate of the earth? w
Crank
Changing the tilt of the axis from 23 degrees to 45 degrees would dramatically change the seasons. They would be more extreme. Increasing the tilt angle means a larger section of the earth would experience one season for a longer period. There would be longer and colder winters and likewise hotter and longer summers.

Explain thermodynamics in how a car runs?
serg [7]

The Otto Cycle can be used to describe how an internal combustion engine works, which allows your car to run by just filling it up with gas. <span>Each of the numbers shown in the figure (1 through 6) represent one stage of the Otto cycle, or one step of the internal combustion process. The common automobile engine is called a “4 Stroke Engine” because it has 4 strokes, which are the Intake Stroke, Exhaust Stroke, Compression Stroke, and Power Stroke. The “Combustion Process” shown in the Otto Cycle in the figure occurs between Strokes 3 and 4, and the “Heat Rejection” shown in the figurea occurs between Strokes 3 and 4.</span>

Light from a laser strikes a diffraction grating that has 5500 lines per centimeter. The central and first-order maxima are sepa
WINSTONCH [101]

.Answer:

491.4 nm

Explanation:

The distance between central and first maxima is,

y=0.455m

And the distance between screen abnd grating is,

L=1.62 m

Now the angle can be find as,

tan\theta=\frac{y}{L} \\\theta=tan^{-1}(\frac{0.455}{1.62})  \\\theta=15.68^{\circ}

Now the grating distance is,

d=\frac{1}{5500} cm\\d=1.82\times 10^{-6}m

Now with m=1 condition will become,

\lambda=dsin\theta

So,

\lambda=1.82\times 10^{-6}m\times sin(15.68^{\circ})\\\lambda=1.82\times 10^{-6}m\times 0.270\\\lambda=491.4\times 10^{-9}m\\\lambda=491.4 nm

Therefore the wavelength of laser light is 491.4 nm.

In a process called pair production, an energetic
vredina [299]

Answer:

(3) mass-energy must be conserved

Explanation:

As we know that gamma rays are mass less and charge less photons which will have sufficient energy.

Now in case of Pair production the gamma photons convert its whole energy into  mass by the law of Einstein's mass energy equivalence relation.

As per his relation we can say

E = \Delta m c^2

here we will have

[tex]\Delta m[\tex] = mass produced

now we also have to think that here the two particles must have a pair of particles and antiparticles so that the combined mass system will have energy equivalent to the energy of gamma photons and also it must follow the conservation of charge

So here it will form an electron and a positron such that total charge will be zero and the energy will be same as energy of gamma photon.
