How do you estimate the density of an object without measuring its mass or volume?

Answers

Answer 1
A simple method based on the moment of forces and Archimedes' principle is described for finding density without measuring the mass and volume of an object. The method involves balancing two unknown objects of masses M1 and M2 on each side of a pivot on a metre rule and measuring their corresponding moment arms….

PLS HELP what is 2x10^3 in long form

Answers

Answer:

2x1000 = 2000

Explanation:

10^3 = 10×10×10 = 1000

exponent , the ^3 means multiply the number by itself 3 times, if it was ^4, it would be 4 times and so forth.

another trick for 10s is just put the 1 and the exponents number of 0's after the 1. so in this case, put three 0's: 1,000

Answer: 2000 or 2000.00 in decimal form if you need

Explanation: Real number to turn Scientific to Real Number you must type the exact scientific notation into a scientific calculator including the Times symbol and it should convert it In other words Multiply the decimal number by 10 raised to the power indicated. Ex: 3.456 x 10^4 = 3.456 x 10,000 = 34560

Answers

Answer:

Sodium and Chlorine

Explanation:

Elements are most likely to form an ionic bond when one element is a metal and the other one is a nonmetal.

Sodium is a metal and Chlorine is a nonmetal.Lithium is a metal and Neon is a noble gas.

So as you can see, sodium and chlorine is the answer.

How do you determine the difference between an element and a compound?

Answers

Answer:  An element is a single atom.

Explanation:

An element cannot be divided into smaller parts (that was true before the physicists built atomic weapons and the Large Hadron Collider).  But the definition of an atom was establish before Einstein, Oppenheimer, and Rutherford.  An element is an atom.  A compound is two or more atoms bonded together.   Carbon is an element, and one carbon all by itself is an atom.  A carbon that has some hydrogens attached (e.g, methane, CH4) are compounds.  An oxygen atom is just sa single O.  We write O2 since that is the form it takes in nature.  O is an atom, O2 is a molecule.

arlon drank 500 mL of softdrink which had a mass of 450 g.

a. 1.11 g/mL c. 0.9 g/mL
b. 50 g/mL d. 225000 g/mL

Answers

Answer:

0.9 g/mL

Explanation:

The density of a substance can be found by using the formula

[tex]d = \frac{m}{v} \\ [/tex]

where

m is the mass

v is the volume of object

From the question we have

m = 450 g

v = 500 ml

[tex]d = \frac{450}{500} = \frac{9}{10} \\ = 0.9[/tex]

We have the final answer as

0.9 g/mL

Hope this helps you

Answer:

B) g/mL

Explanation:

Mass of Oxalic acid (solute) = 11g

Mass of Solution = 500ml

Density = 1.1 g/ml

We know that

A student measured the maximum mass of salt that can dissolve in 100 mL of water at five different temperatures. Which variable should go on the x-axis? A the mass of salt B the volume of water C the mass of water D the temperature of water (i think this is chemistry but it just says science)​

Answers

The independent variable is plotted on the x-axis while the dependent variable is plotted on the y-axis.

The correct answer is D; the temperature of water

It is conventional in science experiments to plot the independent variable on the x-axis and the dependent variable on the y-axis.

As the temperature is manipulated, the measured the maximum mass of salt that can dissolve in 100 mL of water changes. This implies that mass of salt that can dissolve is the dependent variable while the temperature of water is the independent variable.

Hence, the temperature of water is plotted on the x-axis(independent variable) while  mass of salt that can dissolve is plotted on the y-axis(dependent variable).

An electrical engineer measures the frequency of a satellite radio transmission. The frequency is 584 GHz. What is the frequency in hertz? Write your answer in
scientific notation.
CAN SOMEONE HELP ME PLS!!!

Answers

Answer:

584 GHz = 584000000000 Hz

= 584×10^11 Hz

Explanation:

1 Gigahertz ( GHz) = 1000000000 Hz

Satellite uses frequencies and wavelengths to transfer the specific spectrum. The 584 GHz frequency of satellite radio transmission in hertz is 5.84 × 10¹¹ Hz.

What is the frequency?

Frequency, wavelength, and wave number are the functions of the electromagnetic spectrum that are widely used to transfer the various waves for different purposes. Frequency is inversely proportional to wavelength.

The number a wavelength completes in a time period of seconds gives the frequency and is said to be calculated in Hertz (Hz). It is inversely proportional to the time period.

Given,

Frequency = 584 GHz

It is known that 1 Giga hertz = 1000000000 Hz

So, 584 GHz = 584 × 10⁹ Hz

Or 5.84 × 10¹¹ Hz.

Therefore, the frequency of satellite radio transmission in hertz is 5.84 × 10¹¹ Hz.

Scientists once thought the most fundamental building block of matter was a particle called the atom. Now we know that the atom is made of many smaller pieces, known as subatomic particles. Every atom contains a central core called the nucleus, made of particles called protons and neutrons.

An element is a pure substance and is made of only one type of atom; it cannot be broken down into a simpler substance.
