A 60.0-kg runner expends 360 W of power while running a marathon. Assuming that 8.00% of the energy is delivered to the muscle tissue and that the excess energy is removed from the body by sweating, determine the volume of bodily fluid (assume it is water) lost per hour. (At 37.0°C the latent heat of vaporization of water is 2.41 106J/kg.)

An electron enters a region of space containing a uniform 0.0000179-T magnetic field. Its speed is 151 m/s, Find the radius r of the electron\'s path
A uniform density cube of mass m, side 2b, and center at C is placed on a fixed horizontal cylinder of radius r and center O in Earth's gravitational field. The cube is originally put so that C is centered above O, but it can roll from side to side w..
A rifle is aimed horizontally at a target 58 away. The bullet hits the target 2.5 below the aim point. What was the bullet's flight time? What was the bullet's speed as it left the barrel?
A penny of mass 3.10 g rests on a small 22.40 g block supported by a spinning disk of radius 11 cm. The coefficients of friction between block and disk are 0.715 (static) and 0.64 (kinetic) while those for the penny and block are 0.564 (static) an..
When winter arrives, the towers stay the similar distance apart and the bridge deck keeps the similar shape as its expansion joints open. When the temperature drops to -10.0°C, what is the tension in the wire? Take Young's modulus for steel to be ..
If the density of conduction electrons is 10^27 m^3 and the wire has a radius of one millimeter, what is the electrical current through this wire
A K+ ion and a Cl ion are directly across from each other on opposite sides of a membrane 8.9 nm thick. What is the electric force on the K+ ion due to the Cl ion? Ignore the presence of other charges. What direction will it go in relation to the ..
How many times hotter than the Sun's surface is the surface of a star the same size, but that gives off twice the Sun's energy per second (that is, is twice as luminous)?
A container of volume 0.30 m3 contains 3 mol of argon gas at 31°C. suppose argon behaves as an ideal gas, find the total internal energy of the gas.
Illustrate what is the smallest angle of incidence with respect to the top mirror, such that the laser beam hits the mirrors in each way?
Two satellites, A and B, are in different circular orbits about the earth. The orbital speed of satellite A is thirty-six times that of satellite B
