Answer:
a.) kinetic energy from the mallet is transferred first to the orange ball and then to the purple ball.
Explanation:
It is not mechanical like in B, potential energy is not passed from ball to ball like in C, and it is not electromagnetic like in D. Therefore, it is A because the mallet hits(kinetic) the orange ball then the orange ball rolls(kinetic) into the purple ball so that the purple ball rolls(kinetic)
Answer:
When an object experiences a net force, it will accelerate at a rate determined by its mass
Explanation:
A body at rest is considered to have a zero speed, so any force causing the body to move is an unbalanced force and any force causing the body to slow down is also an unbalanced force. An unbalanced force cause acceleration or deceleration i.e a change in speed
Answer:
4 possible combinations of gametes
Explanation:
The animal is considered an heterozygotic dihybrid because it involves two genes that have different alleles for both genes. The dihybrid animal undergoes meiosis to produce gametes. According to Mendel in his laws of segregation and independent assortment, the alleles of the two genes separate into gametes independently of one another to produce 4 types of gametes.
Number of possible combinations of gametes formed by an heterozygote can be determined by using 2^n, where n is the number of characters. Number of characters or genes involved in this case is 2, Hence, 2^2 = 4 gametes.
The allelic combination in the four gametes are: AB, Ab, aB, ab.
