What would be the density if a nugget of gold’s mass of 965g and a volume of 50cm

Answers

Answer 1
Answer:

Answer:

19.3 g/cm³

Explanation:

\text{Density} = \frac{\text{mass}}{\text{volume}}

Mass = 965 g; volume = 50 cm³. So,  

\text{Density} =\frac{\text{965 g}} {\text{50 cm}^(3)} = \text{19.3 g/cm}^(3)
Answer 2
Answer:

p = 19.3 g/cm3


V√3=3.6840315cm :))

What is the difference between covalent bonds and ionic bonds?a. Covalent bonds involve the sharing of pairs of electrons between atoms; ionic bonds involve the sharing of single electrons between atoms.

b. Covalent bonds involve the sharing of electrons between atoms; ionic bonds involve the electrical attraction between atoms.

c. Covalent bonds involve the sharing of electrons between atoms; ionic bonds involve the sharing of protons between atoms.

d. Covalent bonds involve the transfer of electrons between atoms; ionic bonds involve the sharing of electrons between atoms.

Answers

Covalent bond = share of electrons between 2 non metal elements example ( co2,cl2)
They share the neucili

Ionic bond = when metal and non metal atrac each other between them there is a force of atraction

Final answer:
The difference between covalent bonds and ionic bonds is b. Covalent bonds involve the sharing of electrons between atoms; ionic bonds involve the electrical attraction between atoms.

Final answer:

In covalent bonds, atoms share pairs of electrons to achieve a stable electron configuration. This sharing creates a strong bond between the atoms, and they are typically nonmetals. In ionic bonds, there is a transfer of electrons from one atom to another, resulting in the formation of ions with opposite charges.

One atom becomes positively charged (cation), and the other becomes negatively charged (anion). The electrical attraction between these oppositely charged ions holds them together, forming an ionic bond. Ionic bonds typically form between a metal and a nonmetal.

A commercial airplane typically flies at a height of 37,000 feet. If an average cell phone was dropped from an airplane, about how many seconds would it take to reach the ground? Round to the nearest whole number.

Answers

Well depends on how much the phone weighs but I’m sure it’s going off 1 lb so 1000 feet a second so your answer should be 37 seconds

Final answer:

If an average cell phone is dropped from a typical cruising altitude of an airplane, neglecting air resistance, it would take about 107 seconds to reach the ground.

Explanation:

The subject this question falls under is physics because it involves the physical principles of gravity and free fall. If we ignore air resistance (a common simplification in basic physics problems), we can solve this problem by employing the equation for the time (t) of a free-falling object:

t = √(2h/g),

where h is the height the object falls from and g is acceleration due to gravity (about 9.8 m/s^(2)).

Notice that we would need to first convert 37,000 feet to meters (about 11,277.6).

By substituting these values into our formula, we get a value that indicates that a phone falling from the typical cruising altitude of an airplane would take about 107 seconds to hit the ground.

when acceleration is held constant and objects of different mass are observed,are mass and force directly proportional or inversely proportional?Explain.

Answers

Yes. When two things are directly prortional, that means that as one increases, the other increases at the same rate. So, say you have a 2kg object at an acceleration of 2m/s^2. The force would be 4N. If you have a 3kg object at an acceleration of 2m/s^2, the force would be 6N. If two things are inversely proportional, that means that as one thing increases the other decreases at the same rate. A good example of this is in a chemical reaction. If you increase the surface area of the reactants, the reaction time decreases. They are inversely proportional.

How are distant regions of the universe similar to space near earth

Answers

The distant regions of the Universe look older than the space near the Earth. The more distant are, the older is. But the information we can have is lesser due to the distance.
