Answer:
Explanation:
Yes I agree with the statement .
When a person who is perfectly insulated from the earth , touches a Van de Graaff , his body acquires charge . when the hair acquires it, it stands out due to mutual repulsion . It is to be noted here that at pointed areas on a surface , there is larger accumulation of charge. Accumulation of charge is greater at hair tops .
It is also a general observation that when a bird sits on high tension wire , his feather stands out due to the same reason.
Answer:
Green part of the visible spectrum.
X ray part of the electromagnetic spectrum.
Infrared part of the electromagnetic spectrum.
Explanation:
Wien's displacement law
Where, b = Wien's displacement constant = 2.898×10⁻³ mK
T = Temperature in kelvin
So, the wavelength would be of around the green part of the visible spectrum.
So, the wavelength would be of around the X ray part of the electromagnetic spectrum.
Human body temperature = 37°C = 37+273.15 = 310.15 K
So, the wavelength would be of around the Infrared part of the electromagnetic spectrum.
Answer:
You would want to build it with bricks because with glass, the sunlight will come through. Also, make sure to have air conditioning.

Answer:
The identifying characteristics are zero electrical resistivity below a critical temperature, zero internal magnetic field and a critical magnetic field above which superconductivity ceases.
Explanation:
Superconductor material classes include chemical elements (example: mercury or lead)
