The scientist because he is biased and a university isn't. The scientist will say good things about the invention to sell more of it. Hope this helps! ;)
Answer:
ΔW = 1.168 × 10 ⁻²⁰ Joule
Explanation:
Given:
Change in Electric potential Δ V=Vout - Vin=0.073 V
Charge on sodium ions q = 1.6 ×10 ⁻¹⁹ C (+ve because of Missing one electron)
Work done by the electric fore when a sodium ions moves from outside to inside the cell is the change in the Electric potential energy Uout -Uin = ΔU
we have
ΔW =ΔU = q ΔV
ΔW = 1.6 ×10 ⁻¹⁹ C × 0.073 V
ΔW = 1.168 × 10 ⁻²⁰ Joule
Explanation:
r^2= 9×10^9 × 5.87×5.87×10^-16 / 64.9
=47.7× 10^-8
so taking sq. root
r = 6.9 ×10^-4 m
or
r= 6.9×10^ -2 cm
this gives the required seperation
Answer:
Explanation:
Hello.
In this case, since the velocity is computed via the division of the distance traveled by the elapsed time:
The distance is clearly 1743 km and the time is:
Thus, the velocity turns out:
Which is a typical velocity for a plane to allow it be stable when flying.
Best regards.
