<span>he Dawes limit says that the resolving power is 11.6 / d, where d is your eye's pupil's diameter in centimeters. You're eye's pupil can dialate to about 7 mm, or 0.7 cm. So 11.6 / .7 = 16.5 arc seconds, or about a quarter arc minute. However, the standard answer for what people can really see is about 1 arc minute. It's linear, so 10000 / 7 = 1428 times better for the 10 meter scope. However, unless the scope is in space, the atmosphere will take a big chunk from that.</span>
Answer:
F = 1300 N
Explanation:
F = mv²/R = 0.4(100²)/3 = 1333.3333...
Answer:
5/1
Explanation:
Kinetic energy is energy from a moving object and if a pendulum is at the highest point it will go faster.
Explanation:
Wave is defined as a disturbance or oscillation that travels through space-time, accompanied by a transfer of energy. Wave motion transfers energy from one point to another, often with no permanent displacement of the particles of the medium.
The velocity of wave is equal to the product of its wavelength and frequency (number of vibrations per second). Longitudinal waves like sound waves travel through a medium.
Therefore, a wave move from a layer of high velocity to that of a lower velocity the wavelength changes (that is, decreases) as it moves.
