Answer:
Maybe A is the correct answer
Answer:
<em>85.12 μAmp</em>
<em></em>
Explanation:
The battery power output = 17.15 Amp-hr
If the battery is to last 23 years, we have to calculate how many hours there are in 23 years
in one year there are 24 hours x 365 day = 8760 hrs
in 23 years there are 23 x 8760 = 201480 hours
maximum current to be drawn from the battery = (17.15 Amp-hr) ÷ (201480 hours) = 85.12 x 10^-6 Amp = <em>85.12 μA</em>
Answer:
Explanation:
Given that
the ball travelled in positive direction x1 = 20 cm
the ball comes to stop at a distance = x2 = 6 cm
the distance travelled in -ve direction
x3 = x1 - x2 = 20- 6 = 14 cm
total distance co=vered by the given ball
x = x1 +x3 = 20+14 = 34 cm
x = 34 cm
That only the best traits would go through. The weaker trait in the animals would eventually die off.
