Answer:
Science is the study of the natural world by collecting data through a systematic process called the scientific method. And technology is where we apply science to create devices that can solve problems and do tasks. Technology is literally the application of science

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions here.
For convenience write RC=D and solve the ODE dV/dt=-V/D which gives
<span>V=Ae^(-t/D) by separating the variables. </span>
<span>When t=0, V=10 and this gives A=10, </span>
<span>when t=2, V=1 giving 1=10e^(-2/D) and you can find D by taking lns of </span>
<span>each side. D=RC, so R=D/C </span>
<span>You should get 2.90X10^5 ohms</span>
Some bacteria can live with out food or water,but even thought they don't have food nor water they still can reproduce.
Answer:
The ratio is 0.667.
Explanation:
We are given two incandescent lights which have ratings of 75 W and 50 W .
Both bulbs operate at the same voltage.
The equation of power consumed is given by P = 
Therefore the resistance for the 75 W bulb = 
Therefore the resistance for the 50 W bulb = 
Therefore the ratio of the resistance for the 75 W bulb to the resistance of the 50 W bulb is equal to
= 
= 
= 0.667.
The ratio is 0.667.
