It is correct! good job :)
As per the question the wavelength of color of light is given as 560 nm.
We are asked to determine the color corresponding to this wavelength.
The visible spectrum corresponds to the wavelength range of 380 nm to 750 nm.
The visible spectrum contains seven colors of light.
The green light corresponds to the wavelength range of 495 nm to 570 nm.
Hence the correct answer to this question will be green light.
Answer:
Explanation:
a ) Let T be tension in the horizontal cable .
Taking torque about hinge of weight and tension
45000 x 7 x cos37 = 3.5 sin 37 x T
T = 119431 N
b ) If R be the reaction force on the hinge
R sin 37 = 45000 ( vertical force balancing each other )
R = 74775 N
c ) The direction of R will be along the bridge
d ) Moment of inertia of bridge
I = Ml² / 3 = (45000 / 9.8 ) x 14² / 3
= 300000.
When cable breaks , the weight creates a torque about the hinge will creates angular acceleration
Torque by weight about the hinge
= 45000 x 7 x cos 37
= 251570
angular acceleration = torque / moment of inertia
= 251570 / 300000
= .84 radian / s²
Answer
The capacitor should be connected in parallel as parallel connection gives the arithmetic sum of capacitance which will give a corresponding sum of energy while capacitors in series gives the sum of the reciprocal if the individual capacitance
