Where do most asteroids originate?

An LR circuit contains an ideal 60-V battery, a 42-H inductor having no resistance, a 24-? resistor, and a switch S, all in series

Initially, the switch is open and has been open for a very long time. At time t = 0 s, the switch is suddenly closed. How long after closing the switch will the potential difference across the inductor be 24 V? A) 1.6 s B) 1.4 s C) 1.8 s D) 1.9 s E) 2.1 s

A certain automobile tire has a volume of 0.0185 m3. If the absolute (or total) pressure in the tire is 500 kPa and the temperature is 298 K, how many molecules are there inside the tire? (R = 8.31 J/mol ? K, NA = 6.022 x 1023 molecules/mol)

A) 3.25 × 1023 molecules B) 3.25 × 1025 molecules C) 3.25 × 1024 molecules D) 2.25 × 1023 molecules E) 2.25 × 1024 molecules

A wave moves in a rope with a certain wavelength. A second wave is made to move in the same rope with twice the wavelength of the first wave. The frequency of the second wave is half the frequency of the first wave

Indicate whether the statement is true or false

Assume that the average mass of each of the approximately 1 billion people in China is 55 kg. Assume that they all gather in one place and climb to the top of 2 m high ladders. The center of mass of the Earth (mE = 5.90 1024 kg) is then displaced

a. 0 m. b. 1.84 × 10^-23 m. c. 1.84 × 10^-14 m. d. 1.80 × 10^-13 m. e. 2 m.
