Q. A student yells across a street at a concrete wall. The student hears an echo 0.500 seconds later. If the speed of sound in air is 343 m/s, what is the distance from the student to the wall only?
Q. The electric field between plates of a parallel plate capacitor (similar to the ceiling and floor of charge we considered in Monday's class) is the charge density (charge per unit area on one of the plates) divided by epsilon-0, the so-called permittivity of free space, as given in Eq. 18.4. A parallel plate capacitor has a potential difference of 200 V between its plates, which are 0.50 mm apart.
a. What is the magnitude of the electric field between the plates?b. What is the charge density on the plates?c. If the plates have an area of 10.0 square centimeters, how much charge is on the positive plate?
A capacitor is connected across the terminals of an ac generator that has a frequency of 370 Hz and supplies a voltage of 15 V. When a second capacitor is connected in parallel with the first one, the current from the generator increases by 0.27 A. D..
Conclude the magnitude and directional angle
For the circuit shown below, C = 0.113 µF and = 103 V. The switch throw is rotated to contact b after having been at contact for the long time, and 3.47s later the potential difference across the capacitor is equal to 1/2. What is the value of R.
A canoe has the velocity of 0.420m/s southeast relative to the earth. The canoe is on a river that is flowing at 0.570m/s east relative to the earth.
A contact lens is made of plastic with an index of refraction of 1.36. The lens has an outer radius of curvature of +1.91 cm and an inner radius of curvature of +2.41 cm. What is the focal length of lens?
What is the decibel level required for human perception
Although both stars probably formed from the same clump of gas, more massive one must have had its birth slowed so that it became a key -sequence star millions of years later than its less massive companion.
Find (a) magnitude and (b) direction of A - B. (Give the direction as a positive angle with respect to due east). Find out the (c) magnitude and (d) direction of B - A. (Give the direction as a positive angle with respect to due west).
An astronaut on a small planet wishes to measure the local value of g by timing pulses travelling down a wire which has a large object suspended from it. Imagine the wire of mass 3.80 g is 1.60 m long and has a 3.00-kg object suspended from it. A pul..
A professor's office door is 0.80 wide, 3.0 high, and 5.0 thick; has the mass of 25; and pivots on frictionless hinges. A "door closer" is attached to the door and the top of door frame.
he lower block in the figure is pulled on by a rope with a tension force of 20 N. The coefficient of kinetic friction between the lower block & the surface is 0.30. The coefficient of kinetic friction between the lower block & the upper block is a..
Now, as both pipes vibrate at their fundamental frequencies, the beat frequency of 17 Hz is heard. How many centimeters were cut off the end of the second pipe? The speed of sound is 333 m/s.
