Cooking utensils, such as pots, pans and menu trays, are often made from aluminium because it is lightweight and conducts heat well, making it energy-efficient for heating and cooling. These properties also make it a preferred material for packaging.
Answer:
All three characteristics are common between the two
Explanation:
Both water and oxygen are odourless, tasteless, colourless substances and so it is not possible to tell the difference between the two just based off of these three characteristics.
Answer:
7.9m/s
Explanation:
we need to convert the given values to metres and seconds
3/2km = 1500m and 3.5min = 210s
Using the first key equation of accelerated motion:
d = ((vi+vf)/2) x t
1500m = ((6.4+vf)/2) x 210 (plug in values)
3000m = (6.4 + vf) x 210 (get rid of the denominator by multiplying both sides by 2)
14.29 = 6.4 + vf (divide both sides to get rid of time)
vf = 7.885 m/s (subtract 6.4 from the right side to isolate vf)
2 significant digit answer is 7.9m/s
