By definition, acceleration is the change in velocity per change of time. As time passes by, the time increases in value. So, when the acceleration is decreasing while the time is increasing, then that means that the change of velocity is also decreasing with time. So, optimally, the initial velocity and the velocity at any time are very relatively close to each other,
Of the materials listed wood is the best insulator. It would be the least hot if exposed to similar temperatures.
Answer:
velocity = distance / time taken
= 200/4
= 50 m/s
is the correct answer
Because the temperature causes it to go the physical change like if water is froze the temperate just caused it to go through another state of matter another example as if the ice got melted you would need high temperature to cause this change physically. Let me know if I help or if their is anything I can change for you to understand better
A black sweater. Why? Because black is the most absorbent color while as white is reflecting the light. Hope this helps...
