How does upwelling affect the weather of a coastal region?

SIZIF [17.4K]

c.The warm surface water results in moist air and more rainfall.

Explanation:

During upwelling, cold water in the ocean is stirred up and brought to the surface.
The warmer surface water is then taken into deeper parts of the ocean.
Upwelling allows for nutrient mixing in the ocean and allows for useful gases to circulate well.
The warm surface water causes the air to be moisty.
When the air is carried landward towards the coast, it leads to rainfall when the saturated air releases the water.
The air then becomes cold and dry and it rises up.
Therefore, warm surface water results in moist air and more rainfall.

Two positive charges of magnitude 20 micro C and 100 micro C are placed at a distance of 150cm. Calculate the force of repulsion

Luba_88 [7]

$first \: positive \: charge = q1 = 20$

$1micro \: = {1}^{ - 6}$

$1q = 20 \times 10 {}^{ - 6}$

$second \: charge = q2 = 100 \times 10 {}^{ - 6}$

$formula = f = \frac{k \times q1 × q2}{d {}^{2} }$

remember

$k = 9 \times {10}^{9}$

change distance 150cm to 1.5m

putting values

f = $\frac{9 \times 10 {}^{9} \times 20 \times 10 {}^{ - 6} \times 100 \times {10}^{ - 6} }{1.5 {}^{2} }$

A circular flat coil that has N turns, encloses an area A, and carries a current i, has its central axis parallel to a uniform m

Aneli [31]

Answer:

A. Zero

Explanation:

The force on a coil of N turns, enclosing an area, A and carrying a current I in the presence of a magnetic field B, is :

F = N * I * A * B * sinθ

Where θ is the angle between the normal of the enclosed area and the magnetic field.

Since the normal of the area is parallel to the magnetic field, θ = 0

Hence:

F = NIABsin0

F = 0 or Zero

The heating element of an iron operates at 110 V with a current of 9A. (a) What is the resistance of the iron?

Dmitrij [34]

Answer:

(A) 12.222 ohm (B) 990 W

Explanation:

We have given the voltage of the heating element V = 110 V

The current in the heating element i = 9 A

(a) According to ohm's law V =iR

So $110=9\times R$

$R=\frac{110}{9}=12.222ohm$

(b) The power dissipated in the resistor is given by $P=i^2R=9^2\times 12.222=990W$

So the power dissipated = 990 W

You are riding in an elevator that is accelerating upward. Suppose you stand on a scale. The reading on the scale is __________.

olchik [2.2K]

Answer:

greater than your true weight

Explanation:

When going up in an elevator the acceleration of the elevator is added to the acceleration due to gravity. This will increase the reading on the scale.

The expression of the resultant weight will be

$N=m(a+g)$

where,

m = Mass of the person

g = Acceleration due to gravity = 9.81 m/s²

a = Acceleration of the elevator.

Hence, the reading on the scale is <u>greater than your true weight.</u>
