Answer:
d. 114.8 u
Explanation:
The formula for the calculation of the average atomic mass is:
Given that:
<u>For first isotope:
</u>
% = 95.72 %
Mass = 114.9041 u
<u>
For second isotope:
</u>
Since the element has only 2 isotopes, so the percentage of second is 100 - first percentage.
% = 100 % - 95.72 % = 4.28 %
Mass = 112.9043 u
Average Mass = ?
Thus,
<u>Average atomic mass = 114.8 u</u>
Given data:
Mass of cofactor A in an average yeast cell = 96.15 pg
Now:
1 picogram (pg) = 1*
g
1 microgram (ug) = 1*
g
Therefore, 1 pg = 1*ug
Mass of cofactor A in one yeast cell = 96.15 * micro gram
Number of cells in the yeast colony = 105
Therefore, the total mass of cofactor A is given as:
Number of cells * mass of cofactor A per cell
= 105 cells * 96.15 * micro grams/cell = 1.009 * 
micro grams
Since the speed of the bag is constant, it’s kinetic energy remains constant. Since it’s height above the ground is constant, it’s gravitational potential energy is also constant. Since it’s total energy is constant, net work = 0.
Answer:
P-waves compression waves while S-waves are shear waves.
Explanation:
P- waves has the ability to travels through solid, liquid and gaseous medium while S-waves travels through only solid medium and restricted by liquid and gaseous medium. P-waves is a type of seismic wave that will reach first to the recording station as compared to S-waves because P-waves moves faster that S-waves that moves slower so that's why P-waves reach first on the recording station that is located 500 miles away.
Given:
An experimental set-up where there are four test tubes containing different concentrations of hydrochloric acid, all at 25 degrees Celcius. All test tubes were added with 1 gram of Zn cube (at the same time).
The reaction which occurs at the fastest rate is the test tube where HCl concentration is greatest. The high concentration of HCl enhances the speed of the reaction.
