Explanation:
D. Copper and Gold
Copper and gold are used a lot in electrical applications.
Air and wood are insulators and glass is also kinda bad...
Answer:
gravity
Explanation:
I don't know what the explanations would be
Answer:
See explanation
Explanation:
Electric field strength;
E = kq/d^2
k= coulombs constant
q= magnitude of charge
d = distance if separation
If
d is constant
q = 2q
Then;
E = 2 kq/d^2
Hence, the electric field strength will double.
Answer:
Wavelength of the light is 750 nm.
Explanation:
Given that,
Spacing between the lines,
Order of the grating, n = 2
The second order is formed at an angle of 48.5°. The equation of diffraction grating is given by :
or
So, the wavelength of the light is 750 nm. Hence, this is the required solution.
