An object has a force of 10 newtons from the right and 17 newtons from the left. Once the object starts moving toward the right, an additional force of 7 newtons is applied from the right. What can you conclude about the direction of motion of the object after the application of the additional force?

Answers

Answer 1

Answer:

Answer;

The object will not move in either left or right direction, because the net force will be Zero.

Explanation;

Initially, the object experienced an unbalanced forces, 10 N from the right and 17 N from the left, which resulted to a net force of 7 Netwons, and thus the object moved towards the right.
Addition of a force of 7 Newtons from the right, resulted to balanced forces from both direction, thus the object stopped moving in either direction as the net force became zero.
An unbalanced force acting on an object makes the object to move, change direction or its speed. Balanced forces creates a zero net force making the object to have zero acceleration or stop motion.

If a heterozygous type B female and a heterozygous type B male have a baby what are the chances the baby will have type O blood

Answers

Answer: The chances that the baby will have type O is 25%

Explanation: Both the male and female are heterozygous for type B blood, this means that they both have one dominant allele for type B blood and one recessive allele for type O blood. Remember that in the ABO blood system, The alleles for type A and B are dominant while the allele for type O blood is recessive.

This means that the genotypes of both parents for type B blood is BO.

BO x BO = BB, BO, BO, and OO.

Phenotypically, BB and BO will manifest as type B blood while OO will manifest as type O blood.

From the cross between the two parents, one out of the four offsprings has type O blood, therefore the chances of a child having type O blood is 1/4 x 100 = 25%.
