Answer:
The box will move toward you with a force of 10N
Explanation:
If you and your friend are pushing the same box with the same amount of force, those two forces will balance each other out, and the box won't move. In the question, 20N will cancel each other out, and there will be 10N. Your friend is pushing the box with more force than you, so it will move toward you with the remaining force of 10N

Answer:
<h2>100 kcal</h2>
Explanation:
Energy transfers from autotrophs ( producers) to heterotrophs (consumers).
In this way approx 90% of the total energy is consumed by each trophic level, means only 10% energy is transferred from each tropic level.
So as given here, in primary trophic level ( producers), total energy is 10,000 kcal.
Now the 90% (9000 kcal) of this energy is consumed( like in the form of heat and respiration) in trophic level 1 and 10% (1000kcal )is transferred to the trophic level 2( first-order consumers).
And from this energy 90%(900kcal) is consumed in trophic level 2( first-order consumers) , so only 10% (100 kcal) is transferred to the trophic level 3 (second-order consumers).
