Two cars are approaching an intersection. One is 2 miles south of the intersection and is moving at a constant speed of 10 miles per hour. At the same time, the other car is 5 miles east of the intersection and is moving at a constant speed of 20 miles per hour. (a) Express the distance d between the cars as a function of time t. (Hint: At t= 0, the cars are 2 miles south and 5 miles east...
a) A -4 microcoulomb charge moves north at a speed of 500 m/s in a uniform 40 T magnetic field. If the magnetic field points straight down, determine the force on the charge. b) A 4 m wire running 50 degrees S of E carries a 3.0 A current in a 5 T magnetic field pointing due north. Find the force on the wire.
A rectangular coil has side a = 0.055 m, b = 0.095 m, and resistance R=85Ω. It moves into a magnetic field with magnitude B = 0.45 T with speed v= 8.5 m/s.Part (a) As the coil enters the magnetic field, express the magnitude of the magnetic flux going through the loop in terms of the given variables and t, the time since the right side of the loop first entered the field. Part (b) Express the magnitude of the emf,...
Question 5 [6 marks] Two cars move directly away from one another. One car sounds a horn whose frequency is 486 Hz and a person in the other car hears a frequency of 473 Hz. The speed of sound is 343 m/s. The car which sounds its horn is moving twice as fast as the other car. What is the speed of the slower car? [6 marks] Question 6 [5 marks] When an open metal pipe is cut into two...
A rectangular coil has side a = 0.085 m, h = 0.055 m, and resistance R = 45Ω. It moves into a magnetic field with magnitude B = 0.65 T with speed v = 1.5 m/s. Part (a) As the coil enters the magnetic field, express the magnitude of the magnetic flux going through the loop in terms of the given variables.Part (b) Express the magnitude of the emf, ε, induced in the loop in terms of B, a, and v.Part...
Two manned satellites approaching one another, at a relative speed of 0.150 m/s, intending to dock. The first has a mass of 3.50 x 10^3 kg, and the second a mass of 7.50 x 10^3 kg. (a) Calculate the final velocity (after docking) in m/s by using the frame of reference in which the first satellite was orginally at rest. (Assume the second satellite moves in the positive direction. Include the sign of the value in your answer.) (b) What...
1. An electron moves with a speed of 1.00 x 10^5 m/s through planet Spiro’s magnetic field, which has a value of 55.0 x 10^-6 T at a particular location. When the electron moves westward, the magnetic force acting on it is directed straight upward, and when it moves northward, no magnetic force acts on it. a. What is the direction of the magnetic field? Explain your reasoning. b. What is the strength of the magnetic force when the electron...
A proton moves perpendicular to a uniform magnetic field B at a speed of 1.70 times 10^7 m/s and experiences an acceleration of 1.90 times 10^13 m/s^2 in the positive x direction when its velocity is in the positive z direction. Determine the magnitude and direction of the field. Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to...
