Answer:
(a) III and IV
Explanation:
Since a bird is flying it will have kinetic energy as its in motion and potential energy as it is at some height...
The aeroplane is running on run way will have kinetic as it is in a motion and will not have potential energy as it is still on the ground..

Explanation:
Explanation:
Suppose the first number of all three consecutive numbers is "a".
Therefore, next two numbers will be (a + 2), and (a + 4).
It is given that sum of all these three consecutive numbers is 48.
Hence, a + a + 2 + a + 4 = 48
3a + 6 = 48
3a = 48 - 6
3a = 42
a = 42/3 = 14
Therefore, a = 14, a + 2 = 16, and a + 4 = 18
Hence, the three consecutive even numbers are 14, 16, 18. The smallest of all these numbers are 14.
