The phenomenon that is observed when an incident ray travelling in a slower medium strikes the boundary of a faster medium with an angle greater than the critical angle is known as total internal reflection.
Total internal reflection results in the the ray being reflected within the medium, instead of leaving it after undergoing diffraction. This phenomenon is the working principle of optical fibers.
The ballpoint from a pen at a distance of about <u>4000</u> kilometers.
Alpha Centauri is the closest star device. Distance from Earth 4,365 al (forty 000 billion kilometers. The solar (yellow famous person) distance from Earth is 150 000 000 km, the exoplanet distance from Alpha Centauri b (orange famous person) 6 000 000 km.
Shifts in starlight from Proxima Centauri, found over extra than 2 years, screen its 1/3 planet. Astronomers have observed a 3rd planet orbiting Proxima Centauri, the star closest to the solar.
Proxima Centauri, the nearest megastar to our own, remains forty,208,000,000,000 km away. (Or about 268,770 AU.)

Conduction. is a transfer of energy by direct contact
The subject is what the sentence is discussing. It is what the verb/predicate is acting upon, and the primary noun of a sentence.
Answer:8540 kg-g/s
Explanation:
Given
mass of blue car
velocity of blue car
mass of the truck
speed of truck
After collision they stick and lock together
Let v be the velocity of combined system at angle \theta from vertical
Conserving momentum in east direction
------1
Conserving Momentum in Y direction
-------2
squaring and then adding 1 & 2 we get
v=10.95 m/s
initial momentum of car
