The period of vibration t of a tuning fork may be expected to depend on the density p and
young's modulus e of the material of which it is made and the length 1 of its prongs. which of the
following equations could represent the relation between t and the other quantities?
(c)
(a) t= ap (b) t=al
t = ae
vgp
where a is numerical constant and g is the acceleration due to gravity.
the following figures were obtained for a set of geometrically similar steel tuning forks:
lf/hz 2561 288 320 384 1480
i /cm 12.0 10.6 9.6
6.4
8.0
where f is the frequency and is related to t by the equation t = 1/f. use the above data to
confirm, or otherwise, your choice of equations.

i sometimes feel that way too. i feel that i should hurt someone because they hurt me, but i wouldnt do it. that would make things so much worse i have so much experience with this stuff

explanation:

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
