Q. The temperature of the glass surface of a 60 W lightbulb is 67^circ C when the room temperature is 17^circ C. Estimate the temperature of a 160 W lightbulb with a glass bulb the same size. Consider only radiation, and assume that 90 % of the energy is emitted as heat.
Q. An oscillator with a mass of 420 g and a period of 0.900 s has an amplitude that decreases by 1.90% during each complete oscillation.
How to find out the magnitude of the acceleration
A 32.0 kg hammer strikes a steel spike 2.70 cm in diameter while moving with speed of 24.0 m/s. The hammer rebounds with speed 11.0 m/s after 0.110 s. What is an average strain in the spike all through the impact.
A very long non conducting cylinder of diameter 10.0 cm carries charge distributed uniformly over its surface. Each meter of length carries +5.50 C of charge. A proton is released from rest just outside the surface.
Calculate the coil's self-inductance. If the current decreases uniformly from 5.00 to 2.00 in 3.00, estimate the self-induced emf in the coil.
Assume the square wire loop is replaced with a smaller one, made of the same wire that is 0.02 m on a side, half as long as the original.
If a violin string transmits waves at 375 m/s and has 295 Hz as its fundamental frequency, what is the string's length.
A pair of speakers separated by 0.820 m are driven by the same oscillator at a frequency of 652 Hz. An observer originally positioned at one of the speakers begins to walk along a line vertical to the line joining the speakers.
What is the total magnitude of the magnetic flux by the coil before it is rotated.
A 3.2 mass attached to a spring with a spring constant of 114 is oscillating in a vat of oil, which damps the oscillations. If the damping constant of the oil is 10kg/s, how long would it take the amplitude of the oscillations to decrease to 1.0% ..
An ocean liner leaves New York City and travels 37.0° north of east for 171 km. How far east and how far north has it disappeared? In other words, what are the magnitudes of the components of the ship's displacement vector in the directions.
An object is 22 cm in front of a diverging lens that has a focal length of -13 cm. How long in front of the lens should the object be placed so that size of its image is reduced by a factor of 4.
A 38 ohm resistor is made from a coil of copper wire whose total mass is 11.2 g. Find out the length and diameter of the wire.
