This is a number, as of years, days, minutes, or seconds representing such an interval. The
Si standard unit of this is the second
This is the standard Sl (metric) unit of length
This is a change in velocity per time.
This is an object's change in motion per unit time in a specified direction
This is the measured value (always positive) from one point to another.
The vector quantity that defines the distance and direction between two positions.
This is the SI unit of time.
This is a change in the position of a body with respect to time relative to a reference
point.
This is the rate of distance traveled per unit of time, without regard to direction.
This is a line graph that represents acceleration. The slope of the line
w tells us the rate of change in velocity
This is a line graph used to describe the motion of an object. A graphic representation of
velocity. Also used to represent speed.
This is the rate of acceleration of any object falling under the sole
influence of gravity. 9.8m/s

step-by-step 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
