Answer:
(C) increase the distance between the slits in the diffraction grating
Explanation:
This light always form constructive interference, the difference in distance is given λn.
where;
λ is the wavelength
n is the nth maxima
At center fringe, n = 0; the difference is 0
for the first maximum, n= 1, the difference is λ
for second maximum, n = 2, the difference is 2λ
for third maximum, n = 3, the difference is 3λ
From the above illustrations, the wavelength is constant, but the distances between the slits increases, resulting in a higher difference.
Therefore, Option C is the correct answer: increase the distance between the slits in the diffraction grating
The statements of both students are incorrect.
-- Electrical power, just like mechanical power, is expressed in units of watts.
-- 'Coulomb' is the unit of electrical charge.
-- '400 k ohms' means 400,000 ohms of resistance.
-- 'Volt' is the unit of electromotive force (or potential difference).
There are no 'following statements'.
All in all, a very disappointing question.
Answer:
Because it kills people. I have had 6 relatives who have died from it in the past 2 years. It's horrible.
Explanation:
If you're wondering what causes cancer, it is rapid and uncontrollable cell regeneration. The majority of cancers result from random mutations arising during DNA replication in the normal stem cells required during development and tissue maintenance.
Answer: 0.09 m
Explanation:
Centripetal acceleration in terms of tangential speed is:
where r is the radius.
It is given that,
centripetal acceleration of the mouse,
tangential speed ,
Radius of salami is:
Thus, the radius of the salami is 0.09 m.
Answer:
the angle of reflection equals the angle of incidence—θr = θi. The angles are measured relative to the perpendicular to the surface at the point where the ray strikes the surface.
Explanation:
A microscope uses a mirror to reflect light to the specimen under the microscope. ... An astronomical reflecting telescope uses a large parabolic mirror to gather dim light from distant stars. A plane mirror is used to reflect the image to the eyepiece.
