Answer:
Explanation:
The minimum height of a space shuttle from the surface of the earth is 304 kilometers.
So according to this data we calculate the value to g at that height.
We have the formula:
where:
g' = the acceleration due to gravity at the given height 'h' above the earth
R = radius of the earth
g = the acceleration due to gravity at the surface of the earth
Now, using eq. (1)
Answer and Explanation:
The rate (in W) at which heat energy moves from the more blazing article to the colder item increments with the temperature distinction between the items.
The more noteworthy the temperature contrast, the more prominent the rate at which exchange of heat energy takes place.
Thus the temperature difference between the beakers relates in the same manner as described above.
The exchange of heat energy continues until a thermal equilibrium is attained.
The tilt of the earth on its axis causes the seasons.
