Describe the conversion of light energy in a blackberry plant.

Anthocyanins are used in organic solar cells because of their strong light harvesting, and their ability to convert this light energy into electrical energy.

Explanation:

Solar panels plug you into the sun by absorbing solar energy with photovoltaic (PV) cells. When hit with sunlight, they generate electricity which then flows into a device called an inverter which converts the electricity into a form (120 volts, 60Hz) for household use.

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
