The Coriolis effect is the result of which of the following? A. winds spinning off the equator B. the rotation of the earth on its axis C. the different air movements north and south of the equator D. the friction that slows down winds near the earth’s surface

Answers

Answer 1

Answer:

The answer is B. the rotation of the earth on its axis.

Coriolis effect is the effect of the Earth's rotation on theoceans and atmosphere. It is the cause of deflection to the right in thenorthern hemisphere and to the left in the southern hemisphere. Thus, in thenorthern hemisphere, gyres spin clockwise, and in the southern hemisphere, gyres spin counter-clockwise.

Answer 2

Answer:

Answer:

B. the rotation of Earth on its axis

What is the purpose of the coagulation step in water treatment?

Answers

Answer:

It is, however, an important primary step in the water treatment process, because coagulation removes many of the particles, such as dissolved organic carbon, that make water difficult to disinfect. Because coagulation removes some of the dissolved substances, less chlorine must be added to disinfect the water.

Answers

The correct answer is definitely A) the lowest frequency at which a standing wave is possible. I choose this option because standing can occur only at a fundamental frequency and at odd harmonics --> the lowest frequence.

Distance measurements based on the speed of light; used for objects in space

Answers

Answer : Yes, distance measurements based on the speed of light used for objects in space.

Explanation : A light year is measurement of distance that light travel in a one year.

In a one year light travels 9460000000000 kilometer.

We know that, speed of light is $3*10^(8)\ m/s$

and time is 31536000 seconds in 1 year

so, distance= speed of light X time

Now, the light year is $9.4608*10^(15) meter$

Example : The nearest star to earth is about 4.3 light year away.

one car travels east for 360 m over a period of 15 seconds. a second car travels west for 120 m over a period of 5 seconds. what is true about their speeds? their velocities?

Answers

Take it one step at a time.

-- Remember that 'speed' means (distance) divided by (time),
and the direction doesn't matter.

-- Remember that 'velocity' means the speed and the direction.

First car:
360 meters east in 15 sec.
Speed = 360/15 = 24 meters per second
Velocity = 24 meters per second east

Second car:
120 meters west in 5 seconds
Speed = 120/5 = 24 meters per second
Velocity = 24 meters per second west

-- Their speeds (24 and 24) are equal.

-- Their velocities are equal magnitude but opposite (24 east / 24 west).

it's the same because when you divide you can see they have the same velocity

How do you calculate an
object's displacement?

Answers

Answer:

Wecanuseequationsofmotion

$s = ut + (1)/(2) at {}^(2)$

$v {}^(2) = {u}^(2) + 2as \:$

Answer:

Displacement can be calculated by measuring the final distance away from a point, and then subtracting the initial distance. Displacement is key when determining velocity (which is also a vector). Velocity = displacement/time whereas speed is distance/time.

Explanation:

If a cart of 4 kg mass has a force of 8 newtons exerted on it, what is its acceleration?

Answers

Answer:

a=2m/s^2

Explanation:

If a cart of 4 kg mass has a force of 8 newtons exerted on it, what is its acceleration

first foremost, we define basic terms

Mass=is the quantity of matter in a body ,kg

Acceleration= change in velocity per time(m/s^2)

Force= Is that which tends to change a body's state of rest or uniform motion in a straight line.

It is also the pull or push on a body.

From newton's second law of motion which states that rate of change in momentum is proportional to the force applied. Where k=1

Fαm(v/t)

F=km(v/t)

K=1

f=ma

Since v/t= acceleration

velocity/time=accel

8=4a

a=8/4

a=2m/s^2

M = 4kg
F =8N
a..?

F =m.a
8 = 4.a
a = 2m/s^2
