Which of the following is the balanced chemical equation for photosynthesis? a. 6h2o + 6co2    ® 6o2 + c6h12o6 b. c6h12o6  + 6o2 ® 6h2o + 6co2 c. h2o + co2    ® o2 + c6h12o6 d. c6h12o6  + o2 ® h2o + co2  

Aerobic cellular respiration is the process by which all organisms use C6H12O6 (glucose) and 6O2 to make 6CO2, 6H2O and 36 ATP. It is called aerobic because it requires oxygen.

soo that means that the anwser is

a.

6H2O + 6CO2   ® 6O2 + C6H12O6

first let us lay out the formula for potential

and kinetic energy:

pe = mgh

ke = (mv^2)/2

where: m=mass, v=velocity, g=gravitational

acceleration, h=height

calculating for mass using the known values of

pe:

340j = m (9.81 m/s^2) (50ft) (1m/3.28ft)

m = 2.27 kg

the law of conservation of energy states that

energy is neither created nor destroyed. therefore, the change in kinetic

energy from 50 ft to 35 ft would be equal to the change in potential energy

from 50 ft to 35 ft. however it would be opposite in signs since one is losing

while other is gaining.

ke(35ft) – ke(50ft) = - [ pe(35ft) – pe(50ft]

ke(50ft) = 0 since the brick is initially at rest

ke(35ft) = 340j - 2.27kg (9.81 m/s^2) (35ft)

(1m/3.28 ft)

ke(35ft)

= 102.38 j
