let the distance of pillar is "r" from one end of the slab
So here net torque must be balance with respect to pillar to be in balanced state
So here we will have
here we know that
mg = 19600 N
Mg = 400,000 N
L = 20 m
from above equation we have
so pillar is at distance 10.098 m from one end of the slab
Answer: 63 m/s
Explanation: If wheel drops vertically, you can use
conservation of energy : Ep = Ek. mgh = ½mv^2 and
solve v = √(2gh ) = √ (2·9.81 m/s²·200 m) = 62.6 m/s.
NOTE: wheel has also horizontal speed which was not mentioned here.
Force is equal to mass x acceleration. The heavyweight is packing both greater acceleration and mass than the tissue paper.
When his fist comes in contact with the paper, the tissue reacts by exerting its own opposite force, providing a tiny bit of resistance until the fist breaks it apart and passes through.
The fist, although by a a very tiny amount, is decelerated (slowed down) by the paper before it breaks through.
Electrospray ionization mass spectroscopy often results in analyte molecules fragmenting
FALSE
<u>Electrospray ionization mass spectroscopy</u>
It is a technique using electrospray to generate ions for mass spectrometry by applying high voltage to the liquid.
Electrospray ionization is a soft ionization technique.
It is used for production of gas phase ions.
The process of Electrospray ionization mass spectroscopy
1. dispersal of a fine spray charge droplets
2. solvent evaporation
3. ion ejection from highly charged droplets
