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>
Answer: For a total eclipse of the Sun to happen, the Moon must get directly in front of the Sun, as seen from Earth.
Explanation: solar eclipse occurs when something comes between the earth and the sun, casting it's shadow on the surface the earth. For the the sun to be blocked completely. The obstructing body must come directly between.
Answer:
When fuels burn in combustion reactions, they release useful thermal energy (heat). Combustion reactions are used to heat our homes, power most cars, and to generate a lot of our electricity.
Energy production from the reaction is what drives life and human greed. We stay alive by eating carbon-rich compounds, which are then burned in a spectacularly controlled and efficient manner to provide us with energy. It is the all-important energy term in the combustion equation that has made life on Earth possible
The light interference pattern is a series of light and dark stripes.
The bright stripes are areas where there is CONstructive interference.
The dark stripes are areas where there is DEstructive interference.
