A loop of wire carrying a current of 4.0 A is in the shape of a right triangle with two equal sides, each 15 cm long. A 1.4 T uniform magnetic field is in the plane of the triangle and is perpendicular to the hypotenuse. The magnetic force on either one of the two equal sides has a magnitude of:

One object has a mass of 1 kg and another object has a mass of 3 kg. if the speeds are the same, which of the following is true about their kinetic energy?

Aboat radioed a distress call to a coast guard station. at the time of the call, a vector a from the station to the boat had a magnitude of 45.0 km and was directed 15.0° east of north. a vector from the station to the point where the boat was later found is = 30.0 km, 15.0° north of east. what are the components of the vector from the point where the distress call was made to point where the boat was found? in other words, what are the components of vector c = b - a?
