Atrain starts from rest and travels for 5.0 s with a uniform acceleration of 1.5 m/s2. what is the final velocity of the train?

Explanation:

We use the formula to find the final velocity for the movement with constant acceleration:

where

is the final velocity of the train

is the initial velocity of the train, since it starts from rest

is the acceleration,

and is the interval of time,  

So, replacing the values in the formula we get:

The final velocity of the train is  

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
