A Girl is pushing on a 50 kg dresser with 280 N of force. The dresser has a coefficient of static friction of 0.50 and a coefficient of kinetic friction of 0.42. Which of the following statements is true about the state of the dresser ? The dresser does not move, because applied force is less than Fs, max.
The dresser accelerates, because applied force is more than Fs, max
The dresser moves at constant speed, because applied force is more than Fk.
The dresser moves at constant speed , because applied force is more than Fk.

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.

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
