4. Calculate:the mass of the light bulb is the sum of the values on each rider. To get magnified view of the 1-gram rider,place the cursor over that rider (each tick mark represents 0.1 g.)

100-g rider:___________

10-g rider:___________

1-g ruder:___________

Note because the position of the 1-g slider can be estimated to the nearest 0.01 g, the mass measurement is typically recorded to the nearest hundredth.for example, we would write 201.32 g or 146.70 g if the slider is exactly on a 0.1-g tick mark.

5. Practice:use the gizmo to find the mass of the other objects.write their masses below.

Answer:

They were formed right after the "Big Bang" when our known universe originated from pure energy some billions of years ago. The energy was converted to the elementary particles (quarks, gluons, leptons etc...) from which protons and neutrons were formed. From these, atoms of different elements were produced

Answer:

A wave reflection interaction (reflected by the wall)

Explanation:

In a reflection, the propagating wave is bounced off the reflecting surface because the medium of the surface prevents the propagation of the wave through it, such that wave is redirected at an angle equal to the angle of incident on the reflecting surface

Reflection takes place with the different forms of waves, such as sound wave, water waves, and light wave

The objects around us are seen with the aid of reflection of light from a light source such that the reflected light enters our eyes after being reflected on the surface of the object, and the object is seen.

Given parameters:

Density of table salt = 2.16g/cm³

Mass of table salt  = 4.25kg = [tex]\frac{0.00425}{2.16}[/tex][tex]\frac{0.00425}{2.16}[/tex]g (1000g = 1kg)

Unknown:

Volume of table salt = ?

Solution:

To find the volume of the table salt, let us state the relationship between density, mass and volume.

 Density is the mass per unit volume of substance.

           Density  = [tex]\frac{mass}{volume}[/tex]  

Since the unknown is volume;

      Density x volume  = mass

                    Volume  = [tex]\frac{mass}{density}[/tex]

Input the parameters and solve';

                  Volume  = [tex]\frac{0.000425}{2.16}[/tex]  = 1.97 x 10⁻³cm³

Volume of the table salt is  1.97 x 10⁻³cm³

Answer:

a.) & d.)

Explanation:

It should ideally go from Mechanical, Electrical, thermal, light then chemical. I attached a similar example to better explain it.

The two transfers of thermal energy involved in this system are examples of radiation are From the burner to a nearby spoon and From the water to the air Hence, option a & d are correct

Heat transfer is a discipline of thermal engineering that concerns the generation, use, conversion, and exchange of thermal energy between physical systems.

Heat transfer is classified into various mechanisms, such as thermal conduction, thermal convection, thermal radiation, and transfer of energy by phase changes.

According to given question, Energy should ideally go from Mechanical, Electrical, thermal, light then chemical.

Therefore, The two transfers of thermal energy involved in this system are examples of radiation are From the burner to a nearby spoon and From the water to the air Hence, option a & d are correct

Answer:

B)The atoms form a bond with a bond length of 75 pm

Answer:

Its a mixture.

Answer:

An atom is made of protons and neutrons which make up the nucleus and electrons that are around the nucleus. Although almost all the mass of an atom is in the nucleus, most of the space that the atom takes up is occupied by the electrons.

In very simple terms, the electrons are in orbits around the nucleus so most of the volume of the atom is empty space within the volume that the electrons occupy. The behaviour of the electrons is often assumed to be orbits but their actual positions are not that simple.

As a final note, all atoms contain neutrons with the exception of hydrogen which can exist as one proton and one electron.

The Nitric Acid Test

Explanation:

The Nitric Acid Test is used to check if silver is pure or plated. To do so, file a small part of the item in a discreet area where it cannot be seen. Apply a few drops of nitric acid. If the area turns into creamy white, the silver is pure or sterling. If green, it is probably fake or silver-plated.

Answer:

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

From the question

density of metal = 5.78 g/mL

volume = final volume of water - initial volume of water

volume = 24.7 - 22.3 = 2.4 mL

We have

mass = 5.78 × 2.4 = 13.872

We have the final answer as

Answer:

Volume of the [tex]CO_{2}[/tex] gas at 44°C is 258 ml.

Explanation

here,

using Charles' law ,

[tex]\frac{V}{T} =\frac{v}{t}[/tex]

where , V= initial volume          v= final volume

             T=initial temperature    t = final temperature

Given - pressure is constant ,

so , putting the values -

V= 240ml

T= 22 + 273K = 295K                      (since converting celsius into kelvin that

                                                         is +273K )

v =?

t = 44+ 273K = 317K

Now , putting the given values in charles' law ,

[tex]\frac{240ml}{295K} =\frac{v}{317K}[/tex]

240ml x317K = v x 295K     (through cross multiplication )

v =[tex]\frac{240ml\times317K}{295K}[/tex]

= 258ml .

thus , the volume of carbon dioxide in a container at 44°C IS 258ml .
