Please answer asap its 4:45p m right now and i wanna get done with science class lol and i need help because im a bit confused. :) 1C. What is the goal of technology? Explain how a toothbrush achieves this goal

2A. Compare science and technology.
2B. Is a human leg prosthesis an example of science or technology?
2C. Explain how both science and technology must have been involved in the development of a leg prosthesis.

3A. List the positive consequences of using pesticides. then list the negative consequences.
3B. Explain the following statement, "Technology does not provide perfect solutions to problems." use pesticides as an example.

Please give me a real answer, because I have 1 brain cell lol and I really need help :')

think about the oscillation of the toy shown in the video. when the toy is at the highest point of its motion, its velocity is zero and its acceleration is negative.

im not to sure what it is

it would be kevlar ^^

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
