The radius of the circle, in cm, after t seconds would be 50t
The area, A, of the circle after t seconds is expressed in the equation: A = pi * r^2
A = pi * (50T)^2 = pi*2500*t^2
The change of area per unit time is obtained by differentiating the equation
A' = pi*2500*2*t A' = pi*5000*t
when t = 3 secondsA' = pi*5000*3 = 47122 cm2/s
Answer:
False
Explanation:
We still use the old way. It's easier to understand the old way, and its NOT outdated.
Voltage = Current x Resistance
<span>Voltage(?) = 100 x 1.98x10^-4 ohms </span>
<span>Voltage = Current x Resistance </span>
<span>Voltage(?) = 250 x 2.09x10^-4 ohms </span>
<span>Voltage = Current x Resistance </span>
<span>Voltage(?) = 100 x 3.44x10^-4 ohms</span>
the batteries would heat up due to the over load of power not going into any thing and the screw driver is giving it a boost of energy
The electrons stop flowing
