Faraday's Law: A circular coil of 20 turns and radius 5.0 cm is placed with its plane oriented at 90° to a uniform magnetic field of 0.10 T. The field is now increased at a steady rate, reaching a value of 0.50 T after 4.0 seconds. What emf is induced in the coil?
A. 0.016 V B. 0.021 V C. 0.026 V D. 0.031 V E. 0.036 V
What is the maximum number of eclipses that can occur in a year?
A. 7 (four solar and three lunar) B. 4 (two solar and two lunar) C. 2 (one solar and one lunar) D. 7 (five solar and two lunar) or 7 (four solar and three lunar) E. 7 (five solar and two lunar)
The Caloris Basin on Mercury covers a large region of the planet, but few smaller craters have formed on top of it. From this we conclude that
A) erosion destroyed the smaller craters that formed on the basin. B) Mercury's atmosphere prevented smaller objects from hitting the surface. C) only very large impactors hit Mercury's surface in the past. D) the Caloris Basin formed toward the end of the solar system's period of heavy bombardment. E) the Caloris Basin was formed by a volcano.
An electron (m = 9.1 × 10?31 kg, q = ?1.6 × 10?19 C) starts from rest at point A and has a speed of 5.0 × 106 m/s at point B. Only electric forces act on it during this motion. Determine the electric potential difference VA?VB.
A. ?71 V B. +71 V C. ?26 V D. +26 V E. ?140 V
