Plsss pl plsss Two carts weighing 3kg and 2.5kg move on a smooth horizontal surface with speeds of 2m / s and 3m / s, the directions of which are shown in fig. After the collision the two carts move together as a single body. Find the magnitude of the speed and what is the direction of movement of the two carts after hitting them.​

what is the speed of a softball that travels 20m in 2secs

speed = 20/2 = 10 m/s

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

from wikipedia

it is a negative acceleration

i would say
