Answer:

Option (C)

Explanation:

The Coriolis force is defined as the force that generates due to the rotation of the earth around its imaginary axis. Due to the effect of the Coriolis force, the wind gets deviated. The wind is deviated towards the right in the northern hemisphere, whereas the wind gets deviated towards the left in the southern hemisphere.

Due to this changing wind direction, there occurs the low pressure and the high-pressure zone between the polar and the equatorial zone. The low pressure zones are formed at the equator and in temperate regions. Whereas, the high-pressure zones are formed at the tropics and the polar region.

Hence, the correct answer is option (C).

Calculate the weight of an apple of mass 100grams on Earth

11111nata11111 [884]

Answer:

In physics the standard unit of weight is Newton, and the standard unit of mass is the kilogram. On Earth, a 1 kg object weighs 9.8 N, so to find the weight of an object in N simply multiply the mass by 9.8 N. Or, to find the mass in kg, divide the weight by 9.8 N.

A key falls from a bridge that is 45 m above the water. the key falls straight down and lands in a model boat traveling at a con

erastova [34]

Let the key is free falling, therefore from equation of motion

$h = ut +\frac{1}{2}gt^2.$ .

Take initial velocity, u=0, so

$h = 0\times t + \frac{1}{2}g t^2= \frac{1}{2}gt^2$ .

$h = 0\times t + \frac{1}{2}g t^2= \frac{1}{2}gt^2 \\\ t =\sqrt{\frac{2h}{g} }$

As velocity moves with constant velocity of 3.5 m/s, therefore we can use formula

$d= v \times t$

From above substituting t,

$d = v \times \sqrt{\frac{2h}{g} }$ .

Now substituting all the given values and g = 9.8 m/s^2, we get

$d = 3.5 \ m/s \times \sqrt{\frac{2 \times 45 m}{9.8 m/s^2} } = 10.60 m$ .

Thus, the distance the boat was from the point of impact when the key was released is 10.60 m.

How long would it take 2.0x10^20 electrons to pass through a point in a conductor if the current was 10.0A?

inysia [295]

1 coulomb of electric charge is carried by 6.25 x 10^18 electrons

1 Ampere = 1 coulomb per second
10 A = 10 coulombs per second

(2.0 x 10^20 electrons) x (coul / 6.25 x 10^18 electrons) / (10 coul/sec) =

(2.0 x 10^20) / (6.25 x 10^18 x 10) sec = 3.2 seconds
