Visible light or electromagnetic radiation within 400nm to 700nm is responsible for colour of the spectrum.
Explanation:
The electromagnetic spectrum contains radiations of varying wavelength. The radiations with the lowest energy are characterised by the longest wavelength.
Within this spectrum lies the visible light which enables us to see a different colour. The radiations within the range 400nm to 700nm are included in the visible spectrum.
While violet lies at the 400nm spectrum part red colour lies at 700nm part. As the wavelength of the radiation transverses between 400-700 nm, the colour of the object changes accordingly.
It exchanges the cations or the anions of two ionic compounds.
Answer:
Explanation:
It is a question relating to charging of capacitor . For charging of capacitor , the formula is as follows.
Q = CV ( 1 -
)
λ = 1/CR , C is capacitance and R is resistance.
= 1/(500 x 10⁻⁶ x 20 x 10³ )
= .1
λ t = .1 x 20
λ t = 2
CV = 500 X 10⁻⁶ X 5
= 2500 X 10⁻⁶ C
Q = 2500 x 10⁻⁶ ( 1 -
)
= 2500 x 10⁻⁶ x .86566
= 2161.66 μ C .
voltage = Charge / capacitor
2161.66 μ C / 500μ F
= 4.32 V
It is the Jupiter from outer space. And the years from 170 light years away from the Earth.
Answer:
The net torque about the pivot is and the answer is 'c'
c. 
Explanation:

The torque is the force apply in a distance so it is the moment so depends on the way to be put it the signs so:





Now to find the net Torque is the summation of both torques
