A standing wave on a 0.8 m string is described by the relation y = 0.02 sin 5nx cos 100 nt Si units.
(a) What are the amplitude, frequency, and wavelength?
(b) Draw the standing wave pattern. Which harmonic is this? (Counting the lowest frequency as 1, what is the number of this one?)
(c) The mass of the string is 0.008 kg. What is the tension in the string?
You drive on Interstate 10 from San Antonio to Houston, half the time at 60 km/h and the other half at 105 km/h. On the way back you travel half the distance at 60 km/h and the other half at 105 km/h.
Explain why? Because when you go to the grocery store they do not take any recognition as a form of payment!" do you agree or disagree? Examine.
Which color has the highest index of refraction
If the current in the circuit is 0.15 A and the resistances are R1 = 100 ? and R2 = 260 ?, what is the emf of the battery.
A 120 kg mail bag hangs by a vertical rope 4.00 m long. A postal worker then displaces the bag to a position 2.10 m sideways from its original position, always keeping the rope taut.
An aging coyote cannot run fast enough to catch a roadrunner. He purchases on eBay a set of jet-powered roller skates, which provide a constant horizontal acceleration of 15.0 m/s2. The coyote starts at rest 70.0 m from the edge of a cliff at the ins..
A roach that runs for its life because you try to hit it with your physics book runs off the horizontal tabletop with a speed of 0.578 m/s, Find the height of the table
Suppose a heat engine takes in 420 J of energy from a hot reservoir and performs 30 J of work in each cycle.
Water flows at a speed of 1.7 m/s throughout a horizontal pipe having a circular cross section 5 cm in diameter. The pipe widens to a diameter of 14 cm. Treat the water as an idea fluid.
A cubic centimeter in a typical cumulus cloud contains 50 to 500 water drops that have a typical radius of 10µm. For that range, give the lower value and the higher value, respectively, for the following.
A train siren indicating that the stationary train is ready to leave the station has a frequency of 80 Hz. What frequency is perceived by the occupant of a car traveling away from the train at 30 m/s? The speed of sound in air is 343 m/s.
