Why does Quito, Equator has very little changes to the daylight hours throughout the year?

1 answer:

4 0

Because of the position on the equator, the change in rotation of the Earth on its axis throughout the year doesn't affect it much. Unlike the poles, Quito is almost constantly in direct view of the sun. So, because of lack of change in rotation, the daylight hours are hardly varied as Quito is almost constantly in more or less the same spot in relation to the sun.

Which type of mass movement happens very slowly?

diamong [38]

The type of mass movement that happens very slowly is Creep.

Explanation:

Mass movement, usually known as mass wasting, is that the descent movement of a mass of surface materials, like soil, rock or mud. This mass movement generally happens on hillsides and mountains because of the influence of gravity and may happen terribly slowly or terribly quickly.

A car accelerates from rest at 3 m/s for 6 seconds. The velocity of the car after 6 seconds is what ?

Artist 52 [7]

$vf = vi + at$
then solve for v

so
$v = a(t)$
so v = (3m/s^2)(6s)

so v = 18m/s

A 3.0 pF capacitor consists of two parallel plates that have surface charge densities of 1.0 nC/mm2 . If the potential between t

Archy [21]

Answer:

$A=81mm^2$

Explanation:

We know that for a capacitor $Q=CV$ , where Q is the charge of one plate, C the capacitance and V the potential between the plates.

We also know that $Q=\sigma A$ , since $\sigma$ is the surface charge density and A the area of the plate (both equal in our case).

Putting all together:

$A=\frac{CV}{\sigma}$

Which for our values is:

$A=\frac{(3\times10^{-12}F)(27\times10^3V)}{1\times10^{-9}C/mm^2}=81mm^2$

Where we notice that the S.I. units combination FV/C must not have units (we can verify it directly from their definitions or we notice that $mm^2$ is enough to describe an area).
