Answer:
500 THz .
Explanation:
Velocity of light in air = 3 x10⁸ m /s
wave length of light = 600 nm
= 600 x 10⁻⁹ m
= 6 x 10⁻⁷ m
frequency in air = velocity in air / wave length in air
= 3 x 10⁸ / 6 x 10⁻⁷
= .5 x 10¹⁵ Hz
= 5 x 10¹⁴Hz
= 500 x 10¹² Hz
= 500 THz
When light enters the medium of gem , its wavelength and velocity changes in such a way that its frequency remains constant. So in the medium of gem also its frequency remains 500 THz .
209 km/h = 58.0 m/s
2as = v² - u²
Assuming the ball started from rest,
a = (58)² / 2 x 0.11
a = 15,290 m/s²
Answer:
39.4 ml
Explanation:
The displacement is the original volume plus the volume of the other object.
THAT LINK IS A VIRUS NEVER GO TO A LINK and if you go to “goggle” you should see a camera icon and take a picture of the question and get the answer there
A vector is a quantity or phenomenon that has two independent properties: magnitude and direction.
