A complete circuit consists of a 24.0 Volt battery, a 5.60 ohm resistor, and a switch. The internal resistance of the battery is 0.28 ohm. The switch is open (no current is flowing).
A) Find what does an ideal voltmeter read when located across the resistor?
B) Find what does an ideal voltmeter read when located across the switch?
C) Now the switch is closed. What does an ideal voltmeter read when located across the terminals of the battery?
D) Find what does an ideal voltmeter read when located across the resistor?
E) Find what does an ideal voltmeter read when located across the switch?
The Earth is constantly being bombarded by cosmic rays, which consist mostly of protons. Assume that these protons are incident on the Earth's atmosphere from all directions at a rate of 1090. protons per square meter per second.
A rotating wheel has a constant angular acceleration. It has an angular velocity of 5.0 rad/s at time t = 0 s, and 3.0 s later has an angular velocity of 9.0 rad/s. What is the angular displacement of the wheel during the 3.0-s interval?
