Earth DOESN'T have a giant bar magnet inside it; instead, our planet's magnetic field is made by swirling motions of molten iron in Earth's outer core. ... The magnetic poles are near, but not quite in the same places as, the geographic poles. The needle in a compass points towards a magnetic pole

JulijaS [17]

Answer

Caloric flow

Explanation

Depending on the assimilated source of energy, a species population can occupy more than one tropic level. Energy flow in a linear manner in an ecosystem because it moves from level to another and the energy decreases as it transcend from one layer to the other.

While performing an experiment, the student creating the data table is not sure if a measurement from the experiment is a vector
marin [14]

Before coming into conclusion first we have to understand both scalar and vector .

A scalar quantity is a physical quantity which has only magnitude for it's complete specification.

A vector quantity is that physical quantity which not only requires magnitude but also possesses direction for it's complete specification.

So the most important factor that differentiate vector from scalar is the direction.

As per the question the student is doing an experiment where he is recording the data obtained during the process.

In order to arrange them in data table, he should ask about the direction of the quantity under consideration.


Hence the correct option is the third option(C)i.e does the measurement include direction?

Find the momentum p, in the laboratory frame of reference, of a proton moving with a speed of 0.805
user100 [1]
The relativistic formula for the momentum of a particle of mass m and moving at speed v is
p= \frac{mv}{ \sqrt{1- \frac{v^2}{c^2} } }
where c is the speed of light.

In our problem, the speed in terms of c is v=0.805 c, and the mass (still written in terms of c) is m=938 Mev/c^2. Substituting these values in the previous formula, we can find the value of the momentum of the proton:
p= \frac{(938 MeV/c^2)(0.805 c)}{ \sqrt{1-( \frac{0.899c}{c} )^2} } =1273 MeV/c
