A3.30-kg object is hanging from the end of a vertical spring. the spring constant is 57.0 n/m (note: for this question, webassign is using g- 9.8 m/s-) quick how far does this stretch the spring from its rest length? 0.567 v ) 0.567 m. behind the scenes for the rest of the question, webassign will actually be working with 0.567368421052632 m from there, the object is pulled 0.200 m downward and released from rest. complete the following table by calculating the kinetic energy, the gravitational potential energy, the elastic potential energy, and the total mechanical energy e for each of the vertical positions listed. the vertical positions h indicate distances above the point of release, where h = 0 m. before you click submit for the table: this question is sensitive . first check your precision he h (m) pegravity )0 pespring (j) 0.200 0.400 total e (j)

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
