Answer:Well toasting it makes it a solid so that’s a chemical change that happens! Hope this helped!
You need to do spring constant x extension
Because the bridges are higher than the roads. :)
The average acceleration of car during this time is 5 Northeast.
Answer: Option C
<u>Explanation:</u>
The acceleration exerted by an object is the rate of change in velocity the object undergoes with respect to time. Average acceleration is the measure of variation in acceleration in a given interval of time.
Here, final velocity is 30 m/s and initial velocity is 10 m/s. The final velocity is attained by the car after 4 s. Thus, the average acceleration will be
So, the average acceleration is 5 and as the car was moving in the northeast direction, the average acceleration will also be exerting in the northeast direction only.
