Q1. A 2.20 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 heart beats. The reflected sound is after that mixed with the transmitted sound, and 70 beats per second are detected. The speed of sound in body tissue is 1450.
Q2. The system of small objects shown is rotating at the angular speed of 4.0 rev/s. The objects are connected by light, flexible spokes that can be lengthened or shortened. What is the new angular speed if spokes are shortened to 0.15 m? (An effect similar to that illustrated in this problem occurred in the early stages of formation of our Galaxy. As the massive cloud of dust and gas that was source of the stars and planets contracted, an originally small rotation increased with time.)
Explain functionalism, conflict theory and interactionism
The flywheel of an engine has a moment of inertia 2.20 {rm kg} cdot {rm m}^{2} about its rotation axis. What is its final kinetic energy.
Find out the minimum horizontal velocity magnitude of the acceleration of the blocks
If a metal wire carries a current of 23.0 mA, how long does it take for 12.0×1020 electrons to pass a given cross-sectional area anywhere along the wire? The magnitude of the charge on an electron is 1.6 × 10-19 C.
A man pulls a crate of mass 75.0 kg across a level floor. He pulls with a force of 180.0 N at an angle of 26.0° above the horizontal. When the crate is moving, the frictional force between the floor and the crate has a magnitude of 130.0 N. If the cr..

On another planet the simple pendulum consisting of a 0.154 kg mass suspended on a 1.20 m long string has a period of 3.860 seconds. What is acceleration on this planet.
If the magnetic field strength is 0.845 T, what is magnitude and direction of the magnetic force on the wire between the poles
What was the average acceleration throughout the trip
What is the magnitude of the magnetic field. Evaluate this to the tension as the boat is raised and held at rest so the angle becomes 25 degrees.
A 2.30-kg object attached to a spring moves without friction (b = 0) and is driven by an external force given by the expression F = 3.40sin (2pi*t), where F is in newtons and t is in seconds. The force constant of the spring is 35.0 N/m.
A bird sitting in a tree is travelling at 40 km/s relative to the faraway Sun. When the bird drops to the ground below, does it still go 40 km/s, or does this speed become zero.
