A student has two blocks made of the same type of wood. The wooden blocks are both at the same temperature, but Block 1 weighs more than the Block 2
B
Block 1
Block 2
Which block has more thermal energy and why?
A. Block 1 has more thermal energy because it weighs more
O B. Block 2 has more thermal energy because it weighs less
O C. Both blocks have the same amount of thermal energy because they are at the same temperature.
OD. Neither block has any thermal energy because they are not living things

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
