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.
Explanation:
Initial speed of the planet, u = 18.2 km/s = 18200 m/s
Final speed of the planet, v = -22.9 km/s = -22900 m/s
Time interval, t = 2.04 years
Since,
Time interval,
(a) The total change in the planet's velocity is calculated as :
(b) Let a is the average acceleration of the planet. It can be calculated as :
Hence, this is the required solution.
