Given
The Sun is d=150 million kilometers away from Earth.
Light travels at v=3 × 10^5 m/s.
To find
How long does it take for light to reach Earth from the Sun?
Explanation
We know
Time taken is given by
![\begin{gathered} t=\frac{d}{v} \\ \Rightarrow t=\frac{150\times10^6}{3\times10^5} \\ \Rightarrow t=500sec \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20t%3D%5Cfrac%7Bd%7D%7Bv%7D%20%5C%5C%20%5CRightarrow%20t%3D%5Cfrac%7B150%5Ctimes10%5E6%7D%7B3%5Ctimes10%5E5%7D%20%5C%5C%20%5CRightarrow%20t%3D500sec%20%5Cend%7Bgathered%7D)
Conclusion
The time taken is D.500 sec
Answer:
the bottle would stay in its squashed shape, and it will only regain its shape if u remove the cork
Explanation:
because theres not enough air inside to let the bottle to go back its normal form. Its like when u let the air out of a balloon, theres no air inside to let it stay in its 'big or expanded' form.
Answer:
Ball 1 has a mass of 0.5 kilogram and an initial velocity of 1.00 meter/second. Ball 2 has a mass of 1.5 kg and an initial velocity of 0.00 meters/second.
Explanation:
The energy of the red light emitted by a neon atom is 2.827*10^-19J
Light produces photons which might be small packets of power. as the atoms of an object are heated, it results within the manufacturing of photons. The electrons locate pleasure from the warmth and produce extra energy. This power emits inside the shape of a photon, and extra photons are released because the cloth becomes hotter.
The SI unit of wavelength is metre typically denoted as m. at the same time as measuring wavelength the multiples or fractions of a metre is also used. extensively, exponential powers of 10 are used while wavelengths are of a huge property. while there are shorter wavelengths they're expressed as negative exponential.
c=3*10^8 h=6.626*10^-34
wavelength= 703.2*10^-9m
E=2.827*10^-19J
Hence energy of the red light is 2.827*10^-19J.
