The middle C string on a piano is under a tension of 944N. The period and wavelength of a wave on this string are 3.82 ms and 1.26 m, respectively. Find the linear density of the string.
What is the attractive force between the protons. A rocket rises vertically, from rest, with the acceleration of 3.0 m/s2 until it runs out of fuel at an altitude of 1100 m. After this point, its acceleration is that of gravity, downward.
An iron bolt of mass 63.4 g hangs from a string 32.6 cm long. The top end of the string is fixed. Without touching it, the magnet attracts the bolt so that it remains stationary, displaced horizontally 28.5 cm to the right from the before vertical li..
find the work done to move the particle from x = 0 to x = 10.0 m by graphically determining the area under the F versus x graph. (Do this on paper. Your instructor may ask you to turn in this graph.)
What is the potential difference in volts between the plates.
The concepts for finding the change in length of a rod.
The rocket moves for 3.00 s along its initial line of motion with an acceleration of 31.0 m/s2. At this time, its engines fail and the rocket proceeds to move as a projectile. Find out the maximum altitude reached by the rocket.
An object moves up and down y-axis with an acceleration given as a function of time t by the expression a = A sin ω t, where A and ω are constants. What is the period of this motion.
An object, mass 2.96kg, moves in a horizontal circle with a radius of 3.8m. The object has the intial velocity of 32.6 m s-1. If the kinetic coefficient of friction between the object and the surface is 0.31, then number of completed revolutions (..
A 1.6-rm MHz sound wave travels through a pregnant woman's abdomen and is reflected from the fetal heart wall of her unborn baby. The heart wall is moving toward sound receiver as the heart beats.
A yo-yo has a rotational inertia of 970 g·cm2 and a mass of 104 g. Its axle radius is 3.15 mm, What is the magnitude of its linear acceleration
At one instant a bicyclist is 53m due east of a park's flagpole, going due south with a speed of 12m/s. Then 37s later, the cyclist is 53m due north of the flagpole, going due east with a speed of 12m/s. For the cyclist in this 37s interval.
A sotne of mass 0.3 kg tied to the end of string in ahorizontal plane in whriled round in a acircle of radius 1m, What is the tension in the string? What is the max speed with which the stone can be whriled around
