Organisms use and then recycle the energy by decomposing.
1.5 microseconds means . . .
-- 1.5 millionths of a second
-- 1.5 x 10⁻⁶ second
-- 0.0000015 second
Answer:
We can use optical fibers.
Explanation:
The optical fibers are the optical devices which is based on the total internal reflection.
The optical fiber has two layers, one is called core and the other is called cladding.
The refractive index of core is more than the cladding.
As a ray of light falls on the core at more than the critical angle for that pair of media(core and cladding), it suffers the total internal reflection at the interface.
Answer:
Isogonic line is a line joining the points of equal magnetic declination.
Explanation:
Isogonal line is a line that joins the places of equal declination. Also isogonal line is known as the line which connects the point having the same magnetic declination.
Answer:
The block is moving 0.564 m/s after the bullet emerges it.
Explanation:
<u>Step 1:</u> Data given
Mass of the bullet m = 4.86 grams = 0.00486 kg
Initial speed of the bullet u = 306 m/s
Mass of the wooden block m' = 1.37 kg
Final speed of the bullet v = 147 m/s
Initial speed of the block u'= 0 m/s
Final speed of the block = v'
<u>Step 2:</u> conservation law of momentum
mu + m'u' = mv + m'v'
0.00486*306 + 1.37 * 0 = 0.00486*147 + 1.37*v'
1.48716 = 0.71442 + 1.37 v'
0.77274 = 1.37 v'
v' = 0.564 m/s
The block is moving 0.564 m/s after the bullet emerges it.
