Choose the statement that best describes how illumination by monochromatic light affects the oxidation state of electron carriers. Illumination by 700 nm light activates electrons in PSI and reduces NADP , draining PSI of electrons. Electron carriers replace these electrons and become oxidized. Illumination by 680 nm light activates electrons in PSI which are passed on to the electron carriers, reducing them. Illumination by 700 nm light activates electrons in PSI which are passed on to the electron carriers, reducing them. Illumination by 680 nm light activates electrons in PSI and reduces NADP , draining PSI of electrons. Electron carriers replace these electrons and become oxidized.

(newtons first law)

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied

it's 3.2 on edge, i just took the test.

rosa was looking for patterns to predict the products of chemical reactions. she recorded three similar decomposition reactions in the table.she should record 2licl + 3o2.

in the last row of the table. it is the thermal decomposition of chlorate lithium, hence, she should record these products as: lithium chloride ( 2licl ) and oxygen ( 3o2 )   2 > 2 licl + 3o2.
