Have 5 (or any number) doghouses each with a different insulator. Make sure the other variables are controlled so the experiment if fair. Put a thermometer inside the doghouse and record the temperature inside each doghouse. Whatever doghouse has the highest temperature is the best insulator.
Answer:
<h3>75m</h3>
Explanation:
If a cat walk 100m East, this means that it is walking in the positive x direction, the distance will therefore be +100m
If it turns around and walks 25 m west, the direction of movement is in the negative x direction i.e -25m
Taking the sum;
Displacement = +100m - 25m
Displacement of the cat = 75m
hence the cats displacement is 75m
Explanation:
(4566 m / 4 min) × (1 km / 1000 m) × (60 min / h) = 68.49 km/h
Answer:
2000J
Explanation:
work done = force * distance
Work done = 100 * 20
Work done = 2000J
