What is the difference between ocean currents and prevailing winds?
Ocean currents are large-scale movements of water in the ocean, driven by factors like temperature, winds, and Earth's rotation. Prevailing winds are the dominant winds that blow consistently in a particular direction over a specific area. While both ocean currents and prevailing winds impact climate and weather patterns, ocean currents specifically involve the movement of water, while prevailing winds involve the movement of air.
Which is bigger meteoroids or asteroids?
No. A meteoroid is a sand- to boulder-sized particle of debris in the Solar System, while asteroids are small Solar System bodies in orbit around the Sun; they are smaller than planets but larger than meteoroids.
Is there a difference between water and oil in barrel?
Natural seeps are just that - natural. They have been occurring for millennia and the ocean has evolved ways to deal with them. From microscopic bacteria that feed on the petroleum to the simple size of the ocean. The seeps have time to disperse and not contaminate a single large space suddenly.
With spills the area is supersaturated with millions of gallons of oil within hours. The dispersal effect of the waves is generally overwhelmed and even the microbes that thrive on petroleum are hard pressed to do anything of any use.
Man-made efforts to clean the mess sometimes make things worse. Past studies have shown that chemical dispersants can be very toxic. The technology is improving, but its not fool-proof yet.
No one knows what the long term effects of the recent Gulf of Mexico spill might be, but its clear that since the man-made spills are generally localized, the threat may be greater.
What is the realationship between chromatin and chromosomes?
Chromatin is a complex of DNA and proteins found in the nucleus of a cell, which condenses into tightly packed structures called chromosomes during cell division. Chromosomes are formed by the coiling and condensation of chromatin fibers. In summary, chromatin is the material that makes up chromosomes.
How do you tell the difference between sterling and nickel silver?
Nickel silver is an alloy of nickel, copper, and zinc, while sterling silver is an alloy of silver and copper. You can tell the difference between the two by looking for a marking such as "925," which indicates sterling silver's higher silver content compared to nickel silver. Sterling silver will also have a brighter appearance and may tarnish less than nickel silver.
What is functional difference between rods and cones?
Rods are responsible for low-light vision and motion detection, while cones are responsible for color vision and detail. Rods are more sensitive to light and do not detect color, whereas cones require higher light levels and detect different colors through their three subtypes: red, green, and blue.
What is the difference between reflection and bouncing?
Reflection refers to the change in direction when light or sound waves hit a surface and return back in the same medium. Bouncing is a casual term used for the rebounding or redirection of an object off a surface due to impact. Reflection is a more specific term that describes the physics of wave behavior, while bouncing is a more general term that describes the action of an object rebounding off a surface.
What is the two difference between 6C12 and 6C14?
The main difference between carbon-12 (6C12) and carbon-14 (6C14) is the number of neutrons they have in their nuclei. Carbon-12 has 6 neutrons, while carbon-14 has 8 neutrons. This difference in neutron number affects the stability and radioactive properties of the two isotopes.
What is the difference between a U1 and U1L battery?
The main difference between a U1 and U1L battery is their size and dimensions. A U1 battery is typically larger and has a higher capacity compared to a U1L battery, which is smaller and has a lower capacity. U1 batteries are commonly used in applications like lawn tractors, while U1L batteries are used in smaller equipment like lawn mowers or snow blowers.
What is the basic difference between enthalpy of formation?
Ho(reaction) = Hof(products) - Hof(reactants)
Remember to include the state (solid, liquid, gas, or aqueous) for each reactant and product.
Ho(reaction) = Hof(products) - Hof(reactants)
Remember, if there are 2 moles of a reactant or product, you will need to multiply the enthalpy term by 2, if molar enthalpies (heats) of formation are used.
This means that 286 kJ of energy is released when liquid water, H2O(l), is produced from its elements, hydrogen and oxygen, in their standard states, ie, H2(g) and O2(g).
This reaction is written as:H2(g) + ½O2(g) -----> H2O(l) Hfo = -286 kJ mol-1
The standard enthalpy (heat) of formation of water vapour at 298K (25o) is -242 kJ mol-1.
This means that 242 kJ of energy is released when gaseous water (water vapour), H2O(g), is produced from its elements, hydrogen and oxygen, in their standard states, ie, H2(g) and O2(g).
This reaction is written as:H2(g) + ½O2(g) -----> H2O(g) Hfo = -242 kJ mol-1
What is the difference between electrical potential and electromotive force?
Electrical potential refers to the electric potential energy per unit charge at a point in an electric field, measured in volts. Electromotive force (emf) is the energy per unit charge supplied by a source of electrical energy, such as a battery, to drive current through a circuit, also measured in volts. Essentially, electrical potential is a property of a point in the field, while emf is the force that drives the flow of charge.
What is the difference between error and uncertainty?
Error refers to the difference between a measured value and the true value, while uncertainty is a measure of the range within which the true value is likely to lie. Error quantifies the deviation from the true value, while uncertainty quantifies the level of confidence in the measurement.
One statement to accurately describe a difference between a mercury barometer and an aneroid barometer is that a mercury barometer is a closed tube containing mercury. An aneroid barometer is a closed, flexible container of gas.
What is a description of convex lens?
A convex lens is a type of lens that is thicker in the center and thinner at the edges. It converges light rays that pass through it, bringing them to a focal point. This type of lens is commonly used in magnifying glasses, cameras, and eyeglasses to focus light and create clear images.
How can you show the difference between speed and velocity?
Velocity is speed with direction.
To show the difference, show the direction of an object compared with speed alone.
For example, a speedometer shows speed alone, a car on a road can show speed and direction.
How do you tell the difference between silver and metal?
Silver is a metal so I guess you mean iron or steel.
• If it is magnetic it is not silver.
• Silver conducts heat/cold very well. if you put a solid silver object in hot water it will transmit the heat to your fingers quicker than steel.
• You can buy small bottles of acid to test for gold and silver online for less than $10
• If it's big enough you can do an archimedes test by measuring how much water it displaces and finding its density by comparing its volume to weight.
What is the difference between tide and gain?
Tide refers to the rising and falling of sea levels caused by gravitational forces of the sun and moon. Gain, on the other hand, refers to an increase or growth in a specific quantity, such as profit, weight, or knowledge.
What is the essential difference between Ostwald and Ubbelohde viscometer?
The essential difference between Ostwald and Ubbelohde viscometers is the method of measuring viscosity. Ostwald viscometer measures the flow time of a fixed volume of liquid through a capillary, while the Ubbelohde viscometer measures the flow time of a fixed volume of liquid out of a calibrated capillary. Additionally, the Ubbelohde viscometer is more accurate and suitable for measuring the viscosity of transparent liquids.
What is the difference between inertia weight and mass?
Weight' is preferably measured w.r.t center of mass of a body. ex: u are asked to stand vertically with legs apart on the weighing machine,its because ur entire weight is concentrated at the center of the entire mass body.
on the other hand 'mass' is the total physical weigh of ur body along with the forces of gravity !
What is the dependent variable in a lava lamp experiment?
The dependent variable in a lava lamp experiment could be the height of the separated oil and water layers, the speed of the moving bubbles, or the color intensity of the lamp's glow. It is the variable that is being measured and is expected to change in response to the independent variable being tested.
Truvia is made from the stevia leaf extract Reb A, erythritol, and natural flavors. Reb A is a sweet-tasting extract from the stevia plant, while erythritol is a sugar alcohol that provides bulk and texture. Natural flavors are added to enhance the taste of Truvia.
How did lavoisier distinguish between compounds and elements?
Lavoisier distinguished between compounds and elements by conducting experiments to show that compounds can be broken down into simpler substances, while elements cannot be further broken down by chemical means. He also proposed the Law of Conservation of Mass, which states that the total mass of substances present before a chemical reaction is equal to the total mass after the reaction, providing further evidence for the distinction between compounds and elements.
What is the difference between the formula of plumbate and plumbite?
Plumbate ion has a formula of Pb(OH)6 2-, while plumbite ion has a formula of Pb(OH)4 2-. The difference lies in the oxidation state of lead, which is +6 in plumbate and +4 in plumbite.
What is the difference between pharmacies and chemists?
In many countries, there is no difference between pharmacies and chemists. Both terms refer to establishments that dispense medications and provide medical advice. However, in some places, a chemist may refer to a person who formulates or dispenses medication, whereas a pharmacy is the establishment where medications are dispensed.
What is the difference between armature reaction and armature reactance?
