I mean, what is it called. I'm working towards my BS in biology. I'm looking into career options after I graduate, but I'm getting confused and nervous all at the same time. I want to work in a hospital setting mainly. Thankss!!!

I was in a chemical safety class where some one told us that when you don't wear gloves with liquid bleach that the slippery feeling you get is actually your skin melting off. Is this true?

A body oscillates with simple harmonic motion according to the equation:

x = (6.0 m) cos [ ( 3 pi rad/s )t + pi/3 rad ]

At t = 2.0 s, what are (a) the displacement, (b) the velocity, (c) the acceleration, and (d) the phase of the motion?

Also, what are (e) the frequency and (f) the period of the motion?

What equations did you use? Can you explain your answers?

Two thin rectangular sheets (0.06 m * 0.46 m) are identical. In the first sheet the axis of rotation lies along the 0.06 m side, and in the second it lies along the 0.46 m side. The same torque is applied to each sheet. The first sheet, starting from rest, reaches its final angular velocity in 7.4 s. How long does it take for the second sheet, starting from rest, to reach the same angular velocity?

Consider the following half-reactions and E0 values:

Ag+(aq) + e- --> Ag(s) E0 = 0.80 V
Cu2+(aq) + 2 e- --> Cu(s) E0 = 0.34 V
Pb2+(aq) + 2 e- --> E0 = -0.13 V

a/ Which of these metals or ions is the strongest oxidizing agent? Which is the strongest reducing agent?

b/ The half-reaction can be used to construct three different galvanic cells. Tell which cell delivers the higest voltage.

c/ Write the cell reaction for par (b) and calculate the values of E0, ΔG0 (in kilojoules), and K for this reaction.

d/ Calculate the voltage for the cell in part (b) if both ion concentration are 0.010M

If law of conservation of energy is true ..what happens to the mechanical energy of freely rotating shaft .??
if we start an egine and allowed to run.here the chemical energy of fuel is converted into heat.further this heat energy is converted into mechanical energy of rotating shaft.if this shaf is connected to a generator it will produce electric energy & if connectd to pump it will lift fluid.what happens to that energy if we leave that shaft rotate free with out using..is that entire enrgy transferred to AIR surrounding shaft...?????? heat and friction may not be the answers as they exist all the time, no matter we r utilising the energy or not.

A bored college student decides to try bungee jumping. He attaches an elastic bungee cord to his ankles and happily jumps off a tall bridge across a river. He ends up barely touching the water before the cord jerks him back up. What is the mass m of the student? The length of the relaxed cord is y(e); the distance from the bridge to the river surface is y(0) (where y(0) > y(e)), and the spring constant of the elastic cord is k.
Which objects are reasonable to include in the system in this problem? a,the bridge b,the student c,the bungee cord d,the air
e,the river f,the planet earth g,the moon h,the sun
Which assumptions are reasonable to make in this problem?
The student can be treated as a particle moving with constant speed. The student can be treated as a particle moving with constant acceleration. The student cannot be treated as a particle. The air resistance is substantial. The air resistance is negligible.The amount of heat generated in the bungee cord is subs
