<span>The one that does not separate white light into the colors of the visible spectrum is A, rods in the retina of the human eye. The rod is a cells that can work in less extreme light than the other sort of visual photoreceptor, cone cells. Poles are generally discovered accumulated at the external edges of the retina and are utilized as a part of the fringe vision.</span>
Answer:
6 x 10⁻¹⁵ J
Explanation:
d = distance between the plates = 1.5 cm = 0.015 m
E = magnitude of electric field between the plates of the capacitor = 2.5 x 10⁶ V/m
q = magnitude of charge on the electron = 1.6 x 10⁻¹⁹ C
Force on the electron due to electric field is given as
F = q E
F = (1.6 x 10⁻¹⁹) (2.5 x 10⁶)
F = 4 x 10⁻¹³ N
KE₀ = initial kinetic energy of electron at negative plate = 0 J
KE = final kinetic energy of electron at positive plate = ?
Using work-change in kinetic energy
F d = KE - KE₀
(4 x 10⁻¹³) (0.015) = KE - 0
KE = 6 x 10⁻¹⁵ J
Answer:
Weight of the dog on surface of earth is 140.14 Newton.
Given:
mass of the dog = 14.3 kg
To find:
Weight of the dog = ?
Formula used:
Weight of the dog is given by,
W = mg
Where, W = weight of the dog
m = mass of the dog
g = acceleration due to gravity
Solution:
Weight of the dog is given by,
W = mg
Where, W = weight of the dog
m = mass of the dog = 14.3 kg
g = acceleration due to gravity
W = 14.3 × 9.8
W = 140.14 Newton
Weight of the dog on surface of earth is 140.14 Newton.
Explanation:
In order to determine the work done, we will first calculate the internal energy as follows.
=
= 0.171 kJ
Now, we know that relation between internal energy and pressure according to the first law of thermodynamics is as follows.
= q + w
Since, in the given situation heat energy (q) is equal to 0. Therefore,
= w
= 0.171 kJ
Thus, we can conclude that minimum work that must be supplied to accomplish this compression process is 0.171 kJ.
