A transverse wave on a string is described by the following wave function. y = 0.105 sin [(?/12)x + 5?t] where x and y are in meters and t is in seconds. (a) Determine the transverse speed at t = 0.290 s for an element of the string located at x = 1.50 m. m/s (b) Determine the transverse acceleration at t = 0.290 s for an element of the string located at x = 1.50 m. m/s2 (c) What is the wavelength of this wave? m (d) What is the period of this wave? s (e) What is the speed of propagation of this wave? m/s
A wave on a string is described by D(x,t)=(2.00cm)sin[(12.57rad/m)x?(638rad/s)t],where x is in m and t is in s. The linear density of the string is 5.00g/m, What is the maximum speed of a point on the string
Party stores sell small tanks containing 40 g of helium gas. If you use such a tank to fill 0.012 m^3 foil balloons, how many balloons can you expect to fill
I place a 4cm-high object 10cm in front of a 10cm focal length concave lens. How tall is the image
A solenoid is wound with a single layer of insulated copper wire of diameter 2.000 mm and has a diameter of 5.000 cm and is 1.800 m long. How many turns are on the solenoid
A car is traveling 23 m/s when the driver sees a child standing in the road. He takes 0.8 s to react, then steps on the brakes and slows at 6.0 m/s2. Explain how far does the car go before it stops?
A heavy piece of hanging sculpture is suspended by a 146.0 cm long, 8.03 gm wire. When the wind blows hard, wire hums at its fundamental frequency of 113.0 Hz. What is the mass of the sculpture (in kg) assume that the local acceleration due to gravit..
A horizontal 5-cm diameter water jet with a velocity of 18 m/s impinges normally upon a vertical plate of mass 1000 kg. The plate rides on a nearly frictionless track and is initially stationary. When the jet strikes the place, the plate begins to..
An outside loudspeaker (considered a small source) emits sound waves with a power output of 120 W. Find the intensity level in decibels at that distance
Electrons can be “boiled off” of a wire by heating the wire to sufficiently high temperature (typically well over 1000? C). Typically the electrons leave the wire with a fairly low speed which can be approximated as zero
assume that for the couple in, you were told that the girl's mass was two-thirds that of the boy. The boy has a velocity of v = +0.61 m/s. What would be the girl's velocity in this case.
Here's a basketball problem: A 75.0 kg basketball player is running in the positive direction at 8.2 m/s. what is the resulting velocity of the 75.0 kg player
find the childs speed at the lowest point.An elevator has mass 610 kg, not including passengers. The elevator is designed to ascend, at constant speed, a vertical distance of 20.0 m (five floors) in 17.0 s and it is driven by a motor that can provi..
