The acceleration of the car is 2 m/s².

The average velocity of the car is 2 m/s.

The equation acceleration = (final velocity - beginning velocity) / time can be used.

Given:

Initial velocity (u) = 0 m/s (since the car starts from rest)

Final velocity (v) = 20 m/s

Time (t) = 10 s

Using the formula, we can substitute the values:

acceleration = (20 m/s - 0 m/s) / 10 s

acceleration = 20 m/s / 10 s

acceleration = 2 m/s²

Therefore, the acceleration of the car is 2 m/s².

You can use the following equation to determine the average velocity: average velocity = total displacement / total time.

The initial position and the final position are identical since the automobile begins at rest. As a result, the displacement and the ultimate position are equal.

Given:

Displacement = 20 m

Time (t) = 10 s

Using the formula, we can substitute the values:

average velocity = 20 m / 10 s

average velocity = 2 m/s

Therefore, the average velocity of the car is 2 m/s.

25% will have the dominant phenotype, and 75% will have the recessive phenotype.

When purebred or homozygous individuals that differ in a particular trait are mated, all offspring will be heterozygous for that trait. If the trait is inherited as dominant and recessive, all F1 offspring exhibit the same phenotype as the parent homozygous for the dominant trait. Monohybrid matings have a dominant to recessive phenotype ratio of 3:1.

In complete dominance, there is no phenotypic difference between AA and Aa individuals. In imperfect dominance, the phenotype of heterozygous individuals is clearly less intense than that of homozygous individuals for the dominant allele, such that the AA and Aa genotypes produce different phenotypes.

The sensory afferent responsible for reporting the dynamic length of a muscle is the muscle spindle.

Muscle spindles are specialized sensory receptors that are located in the muscle fibers and are responsible for detecting changes in muscle length and tension.

When a muscle is stretched, the muscle spindle is also stretched, causing it to send an impulse to the spinal cord via a sensory neuron. The sensory neuron then relays the information to the brain, which interprets the information and generates a response.

The information provided by muscle spindles is essential for maintaining proper posture and balance, as well as for coordinating movement. The ability to detect changes in muscle length and tension is important for athletes and individuals engaged in physical activity, as it allows them to make quick adjustments to movements and avoid injury.

In addition to muscle spindles, there are other sensory receptors in the muscles and tendons, such as Golgi tendon organs and Pacinian corpuscles, that provide information about tension and pressure in the muscles. Together, these sensory receptors provide a comprehensive picture of the state of the muscles and allow for fine-tuned control of movement and posture.
