Concept explainers

Simple harmonic motion is a type of periodic motion in which an object undergoes oscillatory motion. The restoring force exerted by the object exhibiting SHM is proportional to the displacement from the equilibrium position. The force is directed towards…

Simple Pendulum

A simple pendulum comprises a heavy mass (called bob) attached to one end of the weightless and flexible string.

Oscillation

In Physics, oscillation means a repetitive motion that happens in a variation with respect to time. There is usually a central value, where the object would be at rest. Additionally, there are two or more positions between which the repetitive motion tak…

Chapter 12.2, Problem 13P

In a Hooke’s law experiment, the following weights were attached to a spring, resulting in the following elongations:

Weight (N)	Elongation (cm)
50	2.0
75	3.3
105	4.2
125	5.0
150	6.0
175	7.4
225	9.5
275	11.1

(a) Plot the graph of weight versus elongation and draw the best straight line through the data. (b) From the graph, what weight corresponds to an elongation of 7.5 cm? (c) From the graph, what elongation corresponds to a weight of 220 N? (d) From the graph, determine the spring constant.

1. A light bulb operates at a temperature of 4,300 K and has an emissivity of 0.600 and a surface area of 5.50 mm². How long would the light bulb have to shine on a 2.00 g piece of ice that is at -30.0°C in order to turn the ice into steam at 120°C? Assume all the energy radiated by the light bulb is absorbed by the ice while it becomes liquid and eventually steam. Give an answer in seconds. The following are specific heats for ice, water, and steam. Cice = 2,090 ***C kg kg."C Cwater = 4,186 C Csteam = 2,010 C kg"C The following are latent heats for water.

A 1000-kg car traveling east at 30.0 m/s collides with a 950-kg car traveling north at 25.0 m/s. The cars stick together. Assume that any other unbalanced forces are negligible. What is the speed of the wreckage just after the collision? Please do on paper and show all equations and work done to get to the final answer. Along with any helpful diagrams if needed. These are a part of my review questions in the book but i keep getting different answers from what the book says, it is not a graded assignment***
