Answer:
Okay
Explanation:
First we should quickly remind ourselves of the equation for density:density= mass/ volumeTo calculate the density we need a method of measuring the mass of each object and another method for measuring the volume of each object. To measure the mass in both cases we can simply use a measuring balance. To measure the volume we will need to use 2 separate methods. For the cube we can simply measure the length, height and depth with a ruler, multiply our measurements and we obtain the volume. The statue is a little more tricky because it has an irregular shape so we can't use the ruler anymore. Instead we should use graduated tank/trough of water. First of all measure the amount of water in the tank before putting in the statue. Then submerge the statue in the water and take another measurement of the volume of water in the tank. The statue will displace the water in the tank giving a higher value. We finally subtract the initial volume from the final volume and we should obtain the volume of the statue.We now have all the measurements necessary to calculate the density of both objects!
Shadows blocking part of the light from the star.
A quick warning though this only works on planets either close to the star or planets that are very large.
Also to ensure that the shadows are planets the shadows have to move or orbit around the star. IE The shadow moves
Answer: crystals
Explanation: intrusive igneous rocks are formed by slow cooling magma which contain crystals
The tool used to gauge atmospheric pressure is a barometer. Concerning the device used to gauge air pressure, we have been questioned.
- Mercury is used in barometers. A reservoir of mercury is compressed by atmospheric pressure, and depending on the force of the air, the mercury is propelled up into the tube to a specific height. A straightforward barometer consists of a long glass tube that is filled with mercury and is closed at one end and open at the other. As most cases, the air pressure is expressed in mm Hg.
- By delivering quick, precise information on a range of metrics, Radiometer's products and solutions aid in the diagnosis and treatment of critically ill hospital patients.
- A hygrometer is a device that gauges the moisture content of soil, air, or restricted spaces. Measurements of other quantities, such as temperature, pressure, mass, or a mechanical or electrical change in a substance as moisture is absorbed, are typically used as the basis for humidity measurement systems.
- Voltmeters are used to measure voltages, while thermometers measure temperature.
