Earth's rotation causes winds to veer to the west or to the east. This is known as the Coriolis effect.

Lesson 1.06



Question 5 options:
True
False

Answers

Earth's rotation and spherical shape cause winds to veer to the right (in the northern Hemisphere) or to the left (in the southern Hemisphere) of the direction they want to go.  This is known as the Coriolis effect.

If you didn't know that you're on a rotating Earth, and you looked at the patterns of the winds, you'd think there's some kind of force that's making the airflow veer to the right or left of the direction it actually wants to go.  This is known as the Coriolis force.  It's a"pseudo force", because it doesn't really exist.  It only LOOKS like it's there, because of the Earth's rotation and spherical shape..

The statement "Earth's rotation causes winds to veer to the west or to the east" is true about the Coriolis effect.

What is the Coriolis effect?

Fluid materials such as wind and ocean currents take different directions depending on the hemisphere, this movement of deviation is called the Coriolis effect.

Characteristics of the Coriolis effect

The Coriolis effect occurs when masses of air or water move along terrestrial meridians, and their trajectory and speed are modified by it.

The winds or ocean currents that move along a meridian are diverted by accelerating in the direction of rotation (east) if they go towards the poles or the opposite (west) if they go towards the equator.

Therefore, we can conclude that the force that tends to deflect the trajectory of objects moving across the entire earth's surface is known as the Coriolis effect.

The particles of a substance can have kinetic energy (KE) and potential energy (PE). Which equation best summarizes the internal energy (U) of the substance?​

Answers

Answer:

The internal energy of a substance is equal to the total amount of potential energy and kinetic energy of ALL the particles in the substance.

For example, when the temperature increases (more temperature means more energy), the kinetic energy of the particles in the substance increases.

And when we reach a point near a change of phase (like near fusion point) there is energy used to break the bonds between the particles, then we have an increase in potential energy.

Then we could write the internal energy as:

U = ∑(KEₙ) + ∑(PEₙ)

Where ∑(KEₙ) and ∑(PEₙ) are the sums of the kinetic energy and potential energy of all the particles in the substance.

The equation that best summarizes the internal energy (U) of a substance that has both kinetic and potential energy is U = ∑(KEₙ) + ∑(PEₙ).

WHAT IS INTERNAL ENERGY:The internal energy of a substance is equal to the total amount of potential energy and kinetic energy of all the particles in the substance.

According to this question, the particles of a substance can have kinetic energy (KE) and potential energy (PE).

This means that the internal energy is the sum of the kinetic energy and potential energy of all the particles in the substance.

Therefore, equation that best summarizes the internal energy (U) of a substance that has both kinetic and potential energy is U = ∑(KEₙ) + ∑(PEₙ).

A ball rolls with a speed of 3 m/s across a level table that is 1.5m above the floor. How far along the floor is the landing spot from the table?

Answers

Answer:

d = 1.65 m

Explanation:

Given that,

The speed of a ball, v = 3 m/s

A ball rolls a level table that is 1.5 m above the floor.

We can find how long the ball is in free fall. We can use the second equation of kinematics as follows :

[tex]s=ut+\dfrac{1}{2}gt^2[/tex]

u is the initial speed in the vertical direction

So,

[tex]s=\dfrac{1}{2}gt^2\\\\t=\sqrt{\dfrac{2s}{g}} \\\\t=\sqrt{\dfrac{2\times 1.5}{9.8}} \\\\t=0.55\ s[/tex]

Now, using the formula of velocity.

[tex]v=\dfrac{d}{t}\\\\d=vt\\\\d=3\times 0.55\\\\d=1.65\ m[/tex]

So, the landing spot is at 1.65 m from the table.

The bottom of a ladder must be placed 4 feet from a wall. The ladder is 12 feet long. How far above the ground does the ladder touch the wall? Estimate your answer to the nearest tenth.

Answers

Answer:

Height of wall (Perpendicular) = 11.31 ft (Approx)

Explanation:

Given:

Base Distance (Base) = 4 feet

Height of ladder (Hypotenuse) = 12 feet

Find:

Height of wall (Perpendicular)

Computation:

Perpendicular = √Hypotenuse² - Base²

Height of wall (Perpendicular) = √12² - 4²

Height of wall (Perpendicular) = √144 - 16

Height of wall (Perpendicular) = √128

Height of wall (Perpendicular) = 11.31 ft (Approx)

help as quick as possible plz :(

Answers

Answer:

h = 3.3 m (Look at the explanation below, please)

Explanation:

This question has to do with kinetic and potential energy. At the beginning (time of launch), there is no potential energy- we assume it starts from the ground. There, is, however, kinetic energy

Kinetic energy = [tex]\frac{1}{2}[/tex]m[tex]v^{2}[/tex]

Plug in the numbers = [tex]\frac{1}{2}[/tex](4.0)([tex]8^{2}[/tex])

Solve = 2(64) = 128 J

Now, since we know that the mechanical energy of a system always remains constant in the absence of outside forces (there is no outside force here), we can deduce that the kinetic energy at the bottom is equal to the potential energy at the top. Look at the diagram I have attached.

Potential energy = mgh = (4.0)(9.8)(h) = 39.2(h)

Kinetic energy = Potential Energy

128 J = 39.2h

h = 3.26 m

h= 3.3 m (because of significant figures)

Distance is the total length of path traveled or covered by a body.

So distance is a scalar quantity, it only has magnitude but no direction.

Therefore:

Total distance = 3 m + [tex]\frac{1}{2}[/tex](3)

So;

Take for example you place two eggs in the water. One starts to sink and one remains floating. They have the same volume but the one that sinks is cracked just a little, which as soon as it hits the water, water starts to go in the egg. Then that changes the volume of the egg. (I've done this expirement before) It can also be the way you place the object in the water, or one object has been in the water longer. The buoyancy can be the way they are positioned/placed in the water. One may be more absorbant to the water as well.

Which electromagnetic waves have the shortest wavelength and the highest frequency?

waves

Answers

Answer: Gamma rays (violet) have the shortest wavelengths and the highest frequencies.

Explanation: The wavelength of the gamma rays is less than 0.01 nanometers. The frequency of a wave is inversely proportional to its wavelength. That means that waves with a high frequency have a short wavelength, while waves with a low frequency have a longer wavelength.

The electromagnetic waves have the shortest wavelength and the highest frequency is Gamma rays (violet).

What are gamma rays?

Gamma radiation, from gamma rays (γ), is a type of electromagnetic radiation usually produced by radioactive elements. Gamma rays, due to their high energy, are able to penetrate matter more deeply than alpha or beta radiation.
