Answer:
icebergs float on water because ice is less dense than water. The same is true for a boat: a boat floats on water because, overall, it is less dense than the water.
Explanation:
That's one of the three changes that are called "acceleration".
The other two are:
-- increase in the magnitude
-- change in direction.
Some might call a decrease in the magnitude "deceleration".
Answer:
The final position of the ship after the given time period is 42 km West of B.
Explanation:
Given;
average velocity of the ship, v = 35 km/h
time taken for the ship to reach point D, t = 1.2 hours
The position of the ship after the given time period is calculated as follows;
x = v x t
x = (35 km/h) x 1.2 h = 42 km
x = 42 km West of B.
Therefore, the final position of the ship after the given time period is 42 km West of B.
ANSWER
B - Air density is lower, so there is less heat transfer
EXPLANATION
We want to identify why temperature decreases with higher altitude.
When radiation is absorbed by the earth's surface, it heats the surroundings and the air through convection and conduction.
However, as we ascend higher into the atmosphere, the amount of solar radiation absorbed by the troposphere's gases decreases significantly.
Due to less heat transfer, air molecules start to move away from each other causing a decrease in air density
Hence, we see that temperature decreases with increasing altitude because there is less heat transfer due to the lower air density.
The answer is option B.
