Answer:
-300 N
Explanation:
The key words here are "constant speed". By this, we mean that all the forces on the object (the sailing boat here) are balanced - so they must be equal in magnitude.
Here, we know that the boat has a forward force of 300 N. Because the forces are balanced, then the backward force must also have a force with magnitude 300 N.
However, note that because the backward force is in the opposite direction as the forward force, we must put a negative sign on the 300. So our answer is: -300 N.
Answer:a). base pairing rules
Explanation: A DNA is a double stranded helix in which the two DNA strands are antiparallel and complementary to each other. Watson and Crick developed the base pairing rules that adenine pairs with thymine and cytosine pairs with guanine. The complementary strand are not the same in base sequence and composition instead anywhere adenine is found in one strand, thymine is found in the other strand and anywhere cytosine is found in one strand, guanine occurs in the other strand.
