Answer:
Atomic mass of Sulfur is 32.07.
Explanation:
The four common isotopes of sulfur have masses of 31.972 amu (95.00 % abundance), 32.971 amu (0.76 %), 33.967 amu (4.22 %), and 35.967 amu (0.014 %).
The atomic mass of sulfur will be calculated using atomic mass of there isotopes and their respective decimal abundance.
Atomic mass of sulfur = ∑ isotope * abundance
= {(95/100) *31.972} + {(0.76/100) *32.971} + {(4.22/100) *33.967} + {(0.014/100) *35.967}
= (0.95*31.972) + (0.0076*33.971) + (0.0422*33.967) + (0.00014*35.967)
= 30.3734 + 0.2582 + 1.4334 + 0.00504
= 32.07 amu
Relative atomic mass of sulfur is 32.07
Gravity is 9.8 meters per second. It's a 9.2 mile fall. so just divide the two and you get 0.9388 seconds.
You didn't give options but seedless vascular plants are plants that contain vascular tissue, but do not produce flowers or seeds so for example ferns and horsetails
