An airplane flying at a velocity of 610 m/s lands and comes to a complete stop over a 53 second period. a. Did this airplane speed up or slow down? Explain your reasoning. b. Did this airplane accelerate or decelerate? Explain your reasoning. c. Should your answer be positive or negative? Explain your reasoning. d. Calculate the acceleration.

the airplane slowed down; it came to a stop over 53 seconds, which requires slowing. the airplane decelerated; decelerate is another word for slow down, it also is the opposite of accelerate.  The answer should be negative; negative velocity is slowing down. And the acceleration is ~ -11.509 meters every second

Explanation:

the explanations are included in the answer.

A) The airplane slowed down. It states that the plane lands and come to a complete stop over a 53 second period.

B) It decelerates. The speed doesn't increase. It slows down.

C) The answer should be positive. Although the deceleration is slowing down the plane, it's not going at a negative speed.

D) The answer is 11.5m/s. I divided the velocity by the amount of seconds it takes to make a complete stop.

Explanation: Just cuz

regulation of gene expression. gene expression can be regulated by various cellular processes with the aim to control the amount and nature of the expressed genes. these regulatory proteins bind to dna and send signals that indirectly control the rate of gene expression
