Force=tension-fg sin ∅
=140-mg sin 18.5
=140-124.35
=15.62N
a=f/m=15.62/40=0.39
now,
v²=u²+2as
=2×0.39×80
v²=62.4
v=7.8m/s
Answer:
Convection currents are the result of different heating. Lighter material (warm) rises while heavier (cold) material sinks. This movement of the materials is what causes convection currents! (BTW, it happens in water, in the atmosphere, and in the mantle of Earth!
Explanation:
I hope this helps a little! :)
Answer:
B
Explanation:
because. it reduces the distance between the earth
Answer: Maybe he has the heater on
Explanation: If there is that much temperature then it has to be from something heated.
Answer: e. on the equator and in the Atlantic Ocean
Explanation:
Latitude and Longitude are geographical coordinates.
<u>Latitude</u> is the angular distance between the <u>equatorial line</u>, and a specific point on the Earth. It is measured in degrees and is represented according to the hemisphere in which the point is located, which can be north or south latitude.
In this sense latitude 
refers to the equatorial line that divides the Earth in two hemispheres (North and South).
On the other hand, <u>Longitude</u> represents the specific <u>east–west </u>position of a point on the Earth's surface, being longitude the prime meridian or Greenwich meridian.
So, if we have latitude and longitude 
(positive means it is to the East) we can already know the point is in the equator, and the option that bests describes the coordinates is e.
