1.) I strongly believe that society praises and encourages women to be thin. It doesn't matter the age, women (and men) should be thin for health purposes. Today so many people are obese, and when a parent is obese, often times their children will be as well. I think that ...

A moving rod is 12.0 cm long and moves with a speed of 15.0 cm/s. If the magnetic field is 0.800 T, calculate (a) the emf developed, and (b) the electric field in the rod. I got a)0.0132v and b).12v/m

The rod must move across the field lines. EMF = B V L = (0.80)*(0.15 m/s)*(0.12 m) = 0.0144 V E-field = V/L Read http://tap.iop.org/fields/electromagnetism/page_40030.html for more about this type of problem

A cable passes over a pulley. Because of friction, the tension in the cable is not eh same on opposite side of the pulley. The force in one side is 110 N, and the force on the other side is 100 N. Assume that the pulley is a uniform disk of mass 2.1kg and radius 0.21. ...

95.0 mL of H_2O is initially at room temperature (22 degree C). A chilled steel rod at 2 degree C is placed in the water. If the final temperature of the system is 21.3 degree C, what is the mass of the steel bar?

Sir please let me know that how do we calculate time period of the oscillating rod, t=2pi(2l/3g)^1/2.. & why do we take length 2/3 of the total length??

Aluminum is more reactive than iron, yet it is used today for a variety of applications in which iron would corrode (cans, rain gutters,etc). The reason for the corrosion durability of aluminum is 1. all aluminum products are treated with a plastic coating. 2. aluminum does ...

why is it important to spot samples directly on the marks made on the TLC plate? This is for Thin Layer Chromotography. Is this important so that the solvents move directly up the plate and can be identifies easily? Thanks

First, Jack, let me say you're right but your reasoning is wrong. My mistake, and you probably should have jumped all over it, is I said 9 = 3^x; therefore, x had to be 3. Nuts! 3^3 = 27 so it CAN'T be 3. If 3^x = 9, then x must be 2 because 3 squared = 9. So you'r right, x = ...

The orbit of Halley's Comet around the Sun is a long thin ellipse. At its aphelion (point farthest from the Sun), the comet is 5.1 1012 m from the Sun and moves with a speed of 12.0 km/s. What is the comet's speed at its perihelion (closest approach to the Sun) where its ...

Friction work = initial kinetic energy M*g*mu*X = (1/2) M Vo^2 mu = Vo^2/(2*g*X) = 0.363 Note that the mass does not matter. That number seems too high for something sliding on ice, but that's what I get. Someone probably invented these numbers out of thin air.
