Answer:
4.9 cm³
Explanation:
Given data:
Mass value = 8.3 kg
Density = 1.7 kg/cm³
Volume = ?
Solution;
In given question from the units we got to know that the mass and density value is given and we have to calculate the volume.
Thus, we will apply density formula.
Density = mass/ volume
d = m/v
1.7 kg/cm³ = 8.3 kg/ v
v = 8.3 kg/ 1.7 kg/cm³
v = 4.9 cm³
Thus, the volume is 4.9 cm³.
Why sulfur has a smaller radius than phosphorus?
Answer:
the radius of sulfur is smaller than the radius of phosphorous. This is because atomic radius tends to decrease as you go left to right across the periodic table. Because sulfur is farther right than phosphorous is, it has a a smaller radius.

What are the 3 components of an electromagnet?
Answer:
An electromagnet is a coil of wire wrapped around a bar of iron or other ferromagnetic material. When electric current flows through the wire, it causes the coil and iron bar to become magnetized. An electromagnet has north and south magnetic poles and a magnetic field.
Explanation:
The three main components of an electromagnet are the iron core, copper wire, and an electricity source.
What is an electromagnet?An electromagnet is a magnet in which a coiled or wrapped wire is given electricity. When Current is given to this wire, it acts like a magnet. An electromagnet is used to create a magnetic field.
The three main parts of the electromagnet are the iron core, that is the magnet, which is a small round, or square brick-like. The wire, wire, is made up of copper. The electricity source, by which electricity is given to the electromagnet.
Examples of electromagnets are induction cookers, doorbell rings, etc. They are controllable and adjustable magnets and are used in most electric appliances.
Thus, the three parts are the iron core, copper wire, and an electricity source.

How do you calculate the energy, in joules, of a photon of ultraviolet light with a frequency of 6.8 x 10^15 Hz?
Answer:
E = 45.08×10⁻¹⁹j
Explanation:
Given data:
Energy of photon in joule = ?
Frequency of photon = 6.8×10¹⁵ Hz
Solution:
Formula:
E = h.f
f = frequency
h = planck's constant (6.63×10⁻³⁴Js)
E = energy
Value of planck's constant is 6.63×10⁻³⁴Js.
E = 6.63×10⁻³⁴Js ×6.8×10¹⁵ Hz
Hz = s⁻¹
E = 6.63×10⁻³⁴Js ×6.8×10¹⁵ s⁻¹
E = 45.08×10⁻¹⁹j
Energy is the quantitative unit, which is measured in joules. The energy of a photon of UV light having the frequency 6.8×10¹⁵ Hz is 45.08×10⁻¹⁹ Joules.
Given:
Frequency of photon = 6.8×10¹⁵ Hz
Energy of a photon in joule =?
Usingt the formula of energy:
E = h x v
where,
v = frequency
h = planck's constant (6.63×10⁻³⁴Js)
E = energy
Substituting the values in the equation, we get:
E = 6.63×10⁻³⁴Js ×6.8×10¹⁵ Hz
E = 6.63×10⁻³⁴Js ×6.8×10¹⁵ s⁻¹
E = 45.08×10⁻¹⁹ Joules
Therefore, the energy of a photon in the UV region is 45.08×10⁻¹⁹ Joules

A student measured the mass of some sodium chloride for a lab. the lab called for 6.25 g (the accurate measurement ) , but the student measured 6.00 g instead . what is the percent error for this mass ? Show your work .
Answer:
The answer is
[tex] \huge 4\%[/tex]
Explanation:
The percentage error of a certain measurement can be found by using the formula
[tex]P(\%) = \frac{error}{actual \: \: number} \times 100\% \\ [/tex]
From the question
actual mass = 6.25 g
error = 6.25 - 6 = 0.25
So we have
[tex]p(\%) = \frac{0.25}{6.25} \times 100[/tex]
We have the final answer as

Explanation:
Translation:
A. make a barbecue
B. organize a picnic
C. swimming in the pool
D. to go skiing
Barbecue is usually a summer activity, so we eliminate that.
It would be too cold for a picnic!
It would be too cold to go swimming, and that's more of a summer thing!
Skiing is a snow activity, and since it is winter, it is likely to know.
5. Why does saliva production in the mouth decrease demineralization?
where were atoms formed ?
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:
I hope this helps
Explanation:
Lewis symbols, which are also known as Lewis dot diagrams or electron dot diagrams, are diagrams that represent the valence electrons of an atom. Lewis structures, also known as Lewis dot structures or electron dot structures, are diagrams that represent the valence electrons of atoms within a molecule.
table salt has a density of 2.16g/cm3. a cylindrical box holds 4.25 kg of salt. what is the volume, in cm3 occupied by the salt in the box?
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
A wave hits a wall as shown. A brick wall with a green arrow pointing to the wall from below and right at a shallow angle. Another green arrow starts where the first arrow touched the wall and goes up and left at the same shallow angle. As the wave interacts with a wall, which kind of wave interaction is shown?
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.
