<span>Epsilon
zero is permittivity of free space means how much air or vacuum permits
electric field to travel from one charge to other.It is constant in the coulomb
law. This allow Gauss's a lot easier to solve rather than using K</span>
<u>Answer:</u>
The statement is true statement
<u>Explanation:</u>
Tropical rainforests are dry and green throughout the year. Even between the day and the night, temperatures don't change much. in tropical rainforests The average temperature varies from 70 to 85 °F (21 to 30 °C) .
Throughout tropical rainforests, the climate is quite wet, maintaining a humidity level of 77% to 88% year around which is a high value. The annual rainfall is between 80 and 400 inches (200 and 1000 cm), that is 6-33 feets, and it can rain heavily. It can drain as much as 5 cm (2 inches) in an hour.
The mass of the kid and the sled is 50.0 kg
Explanation:
The sled starts to move when the force applied becomes larger than the maximum force of static friction, which is given by
where
is the coefficient of static friction
m is the mass of the kid + the sled
is the acceleration of gravity
Here the sled starts moving when the force applied is 61.2 N, so
And we also know
Therefore, we can find the mass of the kid and the sled by re-arranging the equation:

Answer:
person that you know and like (not a member of your family), and who likes you
Answer:
The SI system is also called coherent system of units because of the following reasons: ... 1 Newton (SI unit of Force) = 1 Kg (SI unit of mass) x 1 m (SI unit of distance) / s2 (SI unit of time) , therefore 1 Newton is a coherent unit of Force.
