What was the experiment carried out by Hershel & Ritter.

Answers

Answer 1

Answer: Hershel discovered something called Infrared light. It was basically an experiment outdoors and you have a light and when the light hits another surface (like a deck) then that surface heats up

What acceleration does a 9 N force produce in a 3 kg object? Make sure to show your work. (The 4 steps)

Answers

Answer: 3m/s^2

Explanation:

Given that:

Acceleration of object = ?

Force = 9 N

Mass of object = 3 kg

Since force is the product of the mass of an object and the acceleration by which it moves i.e Force = mass x acceleration

9N = 3kg x acceleration

Acceleration = 9N/3kg

Acceleration = 3m/s^2 (3 metres per second square)

Thus, an acceleration of 3m/s^2 is produced.

How do the circulatory system and the respiratory system work together?

Answers

The circulatory system tends to pump blood around the whole body, while the respiratory system tend to facilitate the exchange of gas in the body so then the blood will look totally fresh. In simpler terms, the heart is connected to the lungs through the means of arteries and veins.

List the objects found in the universe in order of size

Answers

This is apartial list of Solar System objects by size, arranged in descending order of mean volumetricradius, and subdivided into several size classes. These lists can also be sorted according to an object'smassand, for the largest objects,volume,densityandsurface gravity, insofar as these values are available. This list contains theSun, theplanets,dwarf planets, many of the largersmall Solar System bodies(which includestheasteroids), all namednatural satellites, and a number of smaller objects of historical or scientific interest, such ascometsandnear-Earth objects.The ordering may be different depending on whether one chooses radius ormass, because some objects are denser than others. For instance,Uranusis larger thanNeptunebut less massive, and althoughGanymedeandTitanare larger thanMercury, they have less than half Mercury's mass. This means some objectsin the lower tables, despite their smaller radii, may be more massive than objects inthe upper tables because they have a higher density.Manytrans-Neptunian objects(TNOs) have been discovered, and their approximate locations in this list are shown, even though there can be a large uncertainty in their measurement.Solar Systemobjects more massive than 1021kilograms(oneyottagram [Yg]) are known or expected to be approximately spherical. Astronomical bodies relax into rounded shapes (ellipsoids), achievinghydrostatic equilibrium, when the gravity of their mass is sufficient to overcome the structural strength of their material. Objects made of ice become round more easily than those made of rock, and many icy objects are spheroidal at far lower sizes. The cutoff boundary for roundness is somewhere between 100 km and 200 kmin radius.[1]The larger objects in the mass range between 1018kgto 1021 kg (1 to 1000zettagrams [Zg]), such asTethys,Ceres, andMimas, have relaxed to anoblate-spheroidequilibrium due to their gravity, whereas the less massiverubble piles(e.g.AmaltheaandJanus) are roughly rounded,but not spherical, dubbed "irregular".

Volume , mass, and weight can be measured with balances, scales, and ?

Answers

If you are talking about volume, then an easy way to measured the volume of a liquid would be with a graduated cylinder. A graduated cylinder is marked with volume units such as milliliter (mL) or the liter (L). One liter equals 1 thousand milliliters.

To measure the volume of a solid you use the formula V = (Length)(Width)(Height)

To measure the volume of a gas you use a graduated cylinder held upside down. At first the cylinder is filled with water. When air is blown into the cylinder, bubbles rise and push some water down. The volume of the water pushed down is equal to the volume of the gas that was blown in.
