An object with a mass of 0.5 kilogram is swung by a string in a horizontal circle of radius 1 meter at a speed of 2 meters per second. as the speed of the object increases, the force needed to keep it in a circular path will

Sonar is used to locate objects underwater by measuring the time it takes an ultrasound sound pulse to reflect back to the receiver. An oceanic depth-sounding vessel surveys the ocean bottom with ultrasonic sound that travels 1530 m/s in seawater.

To test the performance of its tires, a car travels along a perfectly flat (no banking) circular track of radius 130 m. The car increases its speed at uniform rate of at ≡ d |v| dt = 5.22 m/s 2 until the tires start to skid.

Which phenomenon occurs when an object absorbs wave energy that matches the object's natural frequency?

A container, partially filled with water, is resting on a scale that measures its weight. Suppose you place a 200 g piece of wood inside the container filled with water. What happens to the scale reading?

Which is the best analogy of a wave? -A wave is like building a ramp. -A wave is like shaking a hand. -A wave is like water rippling in a pond. -A wave is like knocking down a building.
