Answer:
Terminal voltage = 11.5 V
Power across load = 119.7 W
Power across internal resistance = 5.4 W
Power delivered by battery = 125.2 W
Explanation:
The current in the circuit is given by
where E is the emf of the battery, R us the load resistance and r is the internal resistance.
The terminal voltage is the potential difference across the load resistor.
V = I × R = 10.43 A × 1.1 Ω = 11.5 V
The power across any resistance is given by
For the load resistor,
For the internal resistance,
The power delivered by the battery is

The discrepancy in both answers is due to the approximations. The second answer is better.
Answer:
10 cm
Explanation:
water depth had the biggest difference in survival rates for embryos with UV-B protection versus embryos without UV-B protection is 10 cm . the bar graph attached in the shows that the lengths of yellow and brown bars differ the most at 10 cm.
Hence,The biggest difference between the survival rates of UV-B protected and unprotected can be seen at the depth of 10 cm.
