Abeaker is filled to the brim with water. a solid object of mass 3.00 kg is lowered into the beaker so the object is fully submerged in the water (see the drawing). during this process, 2.00 kg of water flows over the rim and out of the beaker. what is the buoyant force that acts on the submerged object, and, when released, does the object rise, sink, or remain in place?

Bouyant Force is 19.6N and the object will sink

Explanation:

The buoyant force is equal to the weight of displaced water(Archimedes Principle). Since 2.00 kg of water were displaced, the buoyant force would be equal to:

Fb = Fw = mg = (2.00 kg)(9.81 m/s²) = 19.6 N

Where Fb is buoyant force

Where Fw is weight of displaced water

The object will float if the buoyant force is greater than its weight, and sink if the reverse is true. Since the object's mass is 3.00 kg, its weight is:

Fw = mg = (3.00 kg)(9.81 m/s²) = 29.4 N

Since the object's weight, 29.4 N, is greater than the weight of displaced water, the object will sink.

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
