There
are five layers of the atmosphere and these are; troposphere, stratosphere,
mesosphere, thermosphere and exosphere. The first layer, troposphere, is where
we are able to do most of our activities. This is where we can see the formation
of clouds, the production of rain, hail, snow and other weather phenomenon.
Also, this layer is where the greatest amount of air pressure because most of
the molecules of air are in this area. Like us, air has also mass and the
pressure is brought down by the earth’s gravity causing an increase in weight
exerted on you as you descend lower into the atmosphere. So, as you enter into
the other layers of atmosphere above the troposphere, the air pressure starts
to decrease. <span>Below the atmosphere
is the hydrosphere. This is where all liquid forms are located. And since the
seawater has a greater mass than air, it has the greatest pressure. </span>
Answer:
B) more current.
Explanation:
When two lamps are connected in series then we have
now let the two lamps are identical
so we have
now the total resistance of the lamps is given as
now the current in that case is given as
Now when lamps are connected in parallel
net resistance of two lamps is given as
so now we have
so we have
so now the current through the battery will be
So current will be more when two lamps are connected in parallel
Answer:
226.6 N
Explanation:
The work done by the push is given by:
where
p is the magnitude of the push
d is the displacement of the crate
is the angle between the direction of the push and the displacement of the crate
On the contrary, the work done by the frictional force is:
where
is the frictional force, with m=1.00x102 kg being the mass of the crate ang g=9.81 m/s^2 the gravitational acceleration
d is the displacement of the crate
the negative sign is due to the fact that the frictional force acts in the opposite direction to the displacement of the crate.
The net work must be zero, so:
Substituting the previous equations into this one, we find:
which we can solve to find p:
Answer:
The international date line is measured approximately from <u><em>180 degrees longitude</em></u>.
Explanation:
Meridians and parallels are the imaginary lines used to determine degrees of latitude and geographic longitude. They differ in that the meridians are the circumferences that pass through both poles of the globe, while the parallels are the minor circles that are parallel to the equator, and which serve as the basis for determining latitude.
An antimeridian is a meridian exactly opposite to any meridian that is taken from reference, and therefore, the resulting meridian adds 180 º to that taken from reference.
The Greenwich meridian is the one from which the degrees of geographical longitude of each place on the planet are counted over the Equator. Its name is due to the fact that the imaginary line of the 0 ° meridian that passes through the two poles of the Earth crosses the English town of Greenwich.
When taking Greenwich, 0º, as its reference meridian, its antimeridian is the one located on the opposite side to 180º. This meridian is the international date change line.
So the international date change line is an imaginary surface land line drawn over the Pacific Ocean and coincident with the 180 ° meridian.
Then, <u><em>the international date line is measured approximately from 180 degrees longitude.</em></u>
