The human body converts internal chemical energy into work and heat at rates of 60 to 125 W (called the basal metabolic rate). This energy comes from food and is usually measured in kilocalories [1 kcal = 4.186 kJ]. (Note that the nutritional `Calorie' listed on packaged food actually equals 1 kilocalorie). How many kilocalories of food energy does a person with a metoblic rate of 91.0 W require per day? (Assume 100 percent efficiency.)
In an experiment to measure the speed of sound in air, standing waves are set up in a narrow pipe open at both ends using a speaker driven at 687 Hz. What is the air temperature inside the pipe
a rod has resistance r and is placed on parallel rails with negligible resistance within a magnetic field directed
At an outdoor market, a bunch of bananas attached to the bottom of a vertical spring of force constant 16.0 N/m is set into oscillatory motion with an amplitude of 20.0 cm, What is the weight of the bananas in newtons
Two laser beams fall on a screen and illuminate small circular areas. What is the minimum distance between the centers of the circles in order for an observer
A person on a rocket traveling at 0.50c (with respect to the Earth) observes a meteor come from behind and pass her at a speed she measures as 0.50c
The amount of internal enrgy needed to raise temperature of .25kg of water by .2 degreesCis 209.3J. How fast must a .25kg baseball travel in order for its kinetic energy to equal this internal energy.
At the bottom of its path, the ball strikes a 3.80 kg steel block initially at rest on a frictionless surface. The collision is elastic. Find out the speed of the ball just after the collision ?
Only two horizontal forces act on a 4.5 kg body. One force is 5.8 N, acting due east, and the other is 2.7 N, acting 25° north of west. What is the magnitude of the body's acceleration
