<h2>Answer:</h2>
False:
<h2>Explanation:</h2>
Jet streams are like rivers of wind high above in the atmosphere which have a huge influence on climate because they can push air masses and affect weather patterns. Jet streams travel in the tropopause which is the boundary between the turbulent troposphere and the calm, cold stratosphere. So we can say that jet streams lie in stratosphere and not in mesosphere.
A. The position of stars move throughout the year due to gravity
It’s C because just trust
Pluto revolves around a star instead of our SUN. So, it's an "Exo-planet" rather than a Planet. It has declared in 2006 by the scientists.
Hope this helps!
Answer:
3894531 coulombs
Explanation:
1 hour = 3600 seconds
Let g = 10m/s2
The distance that the car travel at 25 m/s over an hour is
s = 25 * 3600 = 90000 m
The total mechanical energy of the car is the sum of its kinetic energy to reach 25 m/s, its potential energy to climb up 200m high hill and it work to travel a distance of s = 90000m with F = 500 N force:
This energy is drawn from the battery over an hour (3600 seconds), so its power must be
The system is 12V so its current is
or 1081.8 Coulombs/s
The the total charge it needs for 1 hour (3600 s) is
C = 1081.8 * 3600 = 3894531 coulombs
