- The clap of thunder was heard for about 34 seconds (T) after the flash of lightning was seen. If the air temperature was 28°C, how far was the sound wave?
A piece of wire has the shape of a semicircle with radius 𝑎 and lies in the first and second quadrant.
The wire is charged with a (line) charge density 𝜆(𝜃)=𝛼sin𝜃 with 𝜃 the angle and 𝛼 a constant.
Calculate the total wire charge 𝑄.
Why is the radius of this semicircle involved? I tried integrating over the angle from 0 to pi, but this gives me the answer 2𝛼, while the answer should be 2a𝛼.

A current-carrying circular plate with A= 32.2 m2 is inclined at 34° with the Earth’s field direction. If the magnitude of the magnetic field is 48 125 nT, solve for the (a) angle between the normal to the surface and the B vector, and the (b) magnetic flux through the antenna
An 88.30-cm wire that carries an electric current of 1.35 A perpendicular to the field has experienced a magnetic force of 9.0✕10 -3 N. Solve for the magnitude of the magnetic field that caused this force.
7.55-μC charged particle with a speed of 30.50 m/s is found in a uniform magnetic field with magnitude 1.2 T. Solve for the magnitude of the magnetic force exerted on the charged particle if the particle is moving perpendicular to the field.
Spheres A, B, and C have charges +8.0 C, +12.0 C, and -5.0 C, respectively. Spheres A and B touched each other and then separated. Sphere A then touched sphere C and then separated. What is the final charge on each sphere assuming that rA = rB = 2rC?
A truck travel down a highway at a speed of 66m/s with it's horns emitting sound at a frequency of 800Hz . What frequency is heard by a passenger in a car traveling at 60m/s in the same direction,as the car and truck approach each other (take velocity of sound in air as 350m/s)
Consider a spring used as a solenoid with a magnetic field of 0.25 T. (a) What is the magnetic field if the spring is stretched to twice its original length? (b) What is the magnetic field if the spring is compressed to half its original length and the current is increased to twice its original value?
