I believe It's either a supernova or a planetary nebula.
Answer:
The sun rays will be focused at the same distance from the mirror.
Explanation:
Laws of reflection do not depend on the refractive index n any form. Hence, the sun’s rays will be focused the same distance from the mirror.
Answer:
Work is done in moving a charge of 2 coulomb across two points having a potential difference of 12 volt is 24 joule .
Explanation:
Distance of fall from rest,
without air resistance = (1/2) (gravity) (time)²
= (1/2) (9.8 m/s²) (95 sec)²
= (4.9 m/s²) (9,025 sec²)
= 44,222.5 meters .
The depth of the mine shaft is five times the height of Mt. Everest !
The answer is true: the pressure of a gas will decrease as temperature decreases in a rigid container.
This is one of the central gas laws called the Gay-Lussac law that states for a given gas at a constant volume, the pressure of the gas is directly proportional to its temperature. We also know that as temperature reduces, so too does molecular interaction. Increased temperature results in increased pressure, and decreased temperature therefore results in decreased pressure.
