Answer:

Explanation:
Since the object is under a circular motion, according to Newton's second law, when the object is at the top of the circle we have:

Where
is the centripetal force and is given by:

Replacing and solving for T:

C. A 1200kg car is going 15m/s
Answer:
<em>conservation of momentum and energy using a series of swinging spheres</em>
Its simple dominant and recessive inheritance patterns and organism would need two recessive alleles(rr) for the trait to be expressed but only one dominant allele for that trait to be expressed (RR or Rr) however in the case of co-dominant alleles the heterozygous state (Rr) would produce a third phenotype rather that the dominant phenotype.
The work done by the man is the product of his applied force and the displacement of the bag and the man gets tired because his internal energy has be converted to work.
<h3>What is work done by the man?</h3>
The work done by the man is the product of his applied force and the displacement of the bag.
<h3>Why the man gets tired</h3>
The man gets tired because his internal energy has be used to do work on the bag.
Thus, the work done by the man is the product of his applied force and the displacement of the bag and the man gets tired because his internal energy has be converted to work.
