Distance walked 34km and displacement should be something like 28km
Answer:
4°C
Explanation:
Water is densest at 4°C. Since dense water sinks, the bottom of the lake will be 4°C.
Answer:
Energy stored in inductor will be 20.797 J
Explanation:
We have given inductance L = 3.54 H
And resistance R = 7.76 ohm
Battery voltage V = 26.6 VOLT
After very long time means at steady state inductor behaves as short circuit
So current 
Now energy stored in inductor 
So energy stored in inductor will be 20.797 J
If you look at a atom under a electron microscope you would use it
