Explanation:
The given data is as follows.
Magnetic field (B) = 0.30 T
Current (I) = 24 A
n = 
charge on electron (e) =
C
Formula to calculate the potential difference is as follows.
V = 
= 
=
V
Therefore, we can conclude that value of potential difference is
V.
Answer:
5) Plant; 6) Heat; 7) never heard of chemosynthesis, sorry :(
