<span>Angular speed = total degree / time
As = 360*(2.5) / 3.0 min (60)
As = 900 deg / 180 s
As =5 Degree / second</span>
Very funny. Can I do all your homework for you?
Answer:
1873
Explanation:
The next time you see someone wearing a pair of Levi's® jeans, remember that these pants are a direct descendant of that first pair made back in 1873. That year, two visionary immigrants — Levi Strauss and Jacob Davis — turned denim, thread and a little metal into what has become the most popular apparel on earth.
Answer:
Explanation:
When a ray of light passes through denser medium to rarer medium and then after refraction it comes back into the denser medium, the phenomenon is called total internal refraction.
There are two necessary conditions for the total internal refraction.
(1) The refraction takes place g=from denser medium to rarer medium.
(2) The angle of incidence in the denser medium should be more than the critical angle for that pair of media.
