At which latitudes do currents of dry sinking air cause the dry conditions of earth's major deserts

1 answer:

5 0

Currents of dry sinking air cause the dry conditions of earth's major deserts at: <span>30° N and 30° S Latitudes

At approximately 30 degrees from the equator, the air that moved up from the equator started to descends. This air, however, could only come from one direction. So when the air is blocked by a mountain, the other side will not receive any water that it contains. This makes the other sides of the mountain became really dry which will eventually cause the formation of the desert.</span>

A 6.75 nC charge is located 1.99 m from a 4.46 nC point charge.

sladkih [1.3K]

Explanation:

Given that,

Charge 1, $q_1=6.75\ nC=6.75 \times 10^{-9}\ C$

Charge 2, $q_2=4.46\ nC=4.46\times 10^{-9}\ C$

The distance between charges, r = 1.99 m

To find,

The electrostatic force and its nature

Solution,

(a) The electric force between two charges is given by :

$F=\dfrac{kq_1q_2}{r^2}$

$F=\dfrac{9\times 10^9\times 6.75\times 10^{-9}\times 4.46\times 10^{-9}}{(1.99)^2}$

$F=6.84\times 10^{-8}\ N$

(b) As the magnitude of both charges is positive, then the force between charges will be repulsive.

Therefore, this is the required solution.

What do u mean by the activity series of metals ??

meriva

Answer:

An activity series is a list of substances ranked in order of relative reactivity. For example, magnesium metal can knock hydrogen ions out of solution, so it is considered more reactive than elemental hydrogen. The activity series is a useful guide for predicting the products of metal displacement reactions.
