1) Find the wavelength of an ultrasonic wave emitted by a bat if it has a frequency of 4.0 * 10^4 Hz.
Suppose this rod can expand in sections like an umbrella shaft. Calculate the final angular speed if it expands in a totaly length of 2.0 m while rotating, assuming its angular momentum is conserved
A 2.9kg block slides with a speed of 1.6m/s on a frictionless horizontal surface until it encounters a spring. a.) If the blockcompresses the spring 4.8cm before coming to rest, what is theforce constant of the spring?
A potter's wheel having a radius 0.49 m and a moment of inertia 10.9 kg·m2 is rotating freely at 52 rev/min. Find the effective coefficient of kinetic friction between the wheel and the wet rag
A wheel is spinning freely on its axis with an angular velocity, w, of 1 rad/s. It has a kinetic energy of 10 Joule. Find what will its kinetic energy be if the angular velocity is 5 rad/s
A parachute dropped from a 30 meter-high cliff falls with a constant velocity of 1.5 meters per second. How long does it take for the stone to hit the ground
IP An object is located to the left of aconvex lens whose focal length is 38 {\rm cm} .The magnification produced by the lens is m_1 = 3.3. To increase the magnification to 4.4, shouldthe object be moved closer to the lens or farther away?

A transformer has 590 primary and 170 secondary turns. An alternating potential of 90 V is applied to the primary
A child sits in a wagon with a pile of 0.403 kg rocks. If she canthrow each rock with a speed of 11.7 m/s relative to the ground, how many rocks must she throw
Model the electromagnetic wave in a microwave oven as a plane traveling wave moving to the left, with an intensity of 26.3 kW/m2. An oven contains two cubical containers of small mass, each full of water.
The position of a mass oscillating on a spring is given by x=(4.5cm)cos[2?t/(0.63s)]. What is the period of this motion? What is the first time the mass is at the position x=0?
