Along electric cable is suspended above the earth and carries a current of 345 a parallel to the surface of the earth. the earth’s magnetic field has a value of 5.6 × 10−5 t and makes an angle of 88.2 ◦ with respect to the cable. what is the magnitude of the force f exerted on a cable of length 46.9 m due to the earth’s magnetic field? answer in units of n

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?

Ashot putter releases the shot some distance above the level ground with a velocity of 12.0 m/s, 51.0 ∘above the horizontal. the shot hits the ground 2.08 s later. you can ignore air resistance. how far did she throw the shot?

What are the differences and relationships between speed, velocity, and acceleration
