a block of mass sliding without friction along a single looped track is to remain on the track at all times, even at the very top of the loop radius.
A) in terms of the given quantities, determine the minimum release height. Next if the actual release hight is 2h, calculate (B) the normal force exerted by the track at the bottom of the loop, (C) the normal force exerted by the track at the loop's top and (D) the normal force exerted by the track after the block exits the loop onto the flat section. note: the mass is under the top of the loop.

o-xylene is actually an aromatic organic compound. It may also be named as o-methyl toluene.( for further simplicity you may consider it as the compound formed when two consecutive H atoms of the Benzene nucleus gets replaced by two methyl groups.)

I know "how" to do this, I just can't figure it out. (Same goes for the other one I posted). I know all the identities to use, it's just getting to the end! This is the last one though!

Two questions I am confused on and office hours didn't help me.

(1) If a solution of [Mo(NH3)6]Cl3 has an absorbance of 1.21 when measured in a cell with a path length of 1.20cm, what is its concentration? The molar absoptivity at the wavelength at which the measurement was obtained is 130 M-1 cm -1.

(2) What is the Ni2+ concentration of a solution prepared by adding 25.0 mL of 0.0400 M Ni2+ to 30.0 mL of water?

The electrocution was done using an insect electrocuter, shaped like a tennis racket. The rotation was instantanous, which means it started immedately after the racket was lifted. There was no physical force exerted at the sides that could cause a torque. Even if there was, the friction would not have allowed the insect to rotate for long. Air was stationary also. Could it be due to unequal distribution of charges that caused centripetal motion, or could there be some other reason? What do you think? I'm puzzled...
