Question

When a gannet flies at a constant rate above the sea, there is a downward force of 30N on the gannet. What is the size of the upward force on the gannet?

a) Less than 30N
b) Exactly 30N
c) More than 30N
d) None

Answer 1

The size of the upward force on the gannet is exactly 30N.

Step-by-step explanation:

When a gannet flies at a constant rate above the sea, there is a downward force of 30N on the gannet. The upward force on the gannet is equal in magnitude to the downward force. Therefore, the size of the upward force on the gannet is exactly 30N, option b.
