Answer:d
Explanation:
From Gauss law Electric field inside a surface is directly proportional to the charge enclosed in it.
Electric field inside a spherical shell is zero and hence there is no charge inside the spherical shell because q charge induces a -q charge on inside surface of spherical shell.
and to counter it there is q charge on the surface. So total charge outside the surface is Q+q
Answer:
When elements bond together or when bonds of compounds are broken and form a new substance
Explanation:
Answer:
Phase change
Explanation:
This term describes the changes of a state of matter between various states of aggregation without a change in its composition, that is, the transitions between solid, liquid, and gaseous states of matter, due to the effects of temperature and / or pressure.
<span>the body is moving horizontally, it doesnt matter watever kind of horizontal forces are acting.
Therefore the normal force is equal to the weight
N=mg=4.2*9.8=41N
Note: the other data in the problem have no relevance
answer
</span> the normal force on the sled is 41N
The big hits the windshield with a force of 10N. Newton’s third law states that every action must have an equal and opposite reaction
