Writing Physics lab write up Questions: 1. Derive the final expression from the theory section using torque instead of force. 2. What is the net force on the wires in the balance that run parallel to the solenoid? 3. Devise another way to run this experiment without using a mass on the other end of […]
Assignment 1. The visible surface of the sun is called what? 2. Granulation is caused by what type of currents in the outer part of the sun? 3. What is the outermost part of the sun’s atmosphere called? 4. How did Galileo conclude that the sun was rotating? 5. The […]
ASSIGNMENT Mercury, the planet closet to the Sun has a magnetic field, as does the Earth, the third planet. But the second and fourth planets from the Sun – Venus and Mars, have no magnetic field. Mercury, Venus, the Earth and Mars are all “terrestrial” planets – why do two of them have magnetic fields […]
PHYSICS The current-carrying wire loop in the figure on the left lies all in one plane and consists of a semicircle of radius 20 cm, a smaller semicircle with the same center, and two radial lengths. The smaller semicircle is rotated out of that plane by angle θ, until it is perpendicular to the plane. […]
Magnetic field and current related questions An initially uncharged capacitor with a capacitance of C= 00 pF is connected in series with resistor with a resistance of R= 4.5 kn. If this series combination of circuit elements is attached to an ideal battery with an emf of f= 450 V by means of a switch […]
