6 Two cyclists, A and B, have displacements 0 km and 70 km, respectively. At t=0 they
begin to cycle towards each other with
velocities 15 km h and 20 km h-',
respectively. At the same time, a fly that was
sitting on A starts flying towards B with a
velocity of 30 km h-'. As soon as the fly
reaches B it immediately turns around and
flies towards A, and so on until A and B meet.
(a) What will the displacement of the two
cyclists and the fly be when all three
meet?
(b) What will be the distance travelled by the
fly?

answer; i believe the correct answer is (40,000 j) good luck

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
