Maria’s class has learned how to drop an egg without breaking it. After 0.2 s, the kinetic energy of the falling egg is 0.5 J. If its mechanical energy is 2.3 J, what is its potential energy?

A. 1.2 J
B. 1.8 J
C. 2.8 J
D. 4.6 J

Answers

2.8 J

this is a right answer helpful

The Potential energy of the body is 11.8 Joules

The mechanical energy of the egg is given by the formula:

Mechanical energy = Potential energy + kinetic energy

Given the following parameters;

Mechanical energy = 2.3 JoulesKinetic energy = 0.5 Joules

From the formula:

Potential energy = ME = KE

Potential energy = 2.3 - 05

Potential energy = 1.8 Joues

Hence the potential energy of the body is 11.8 Joules

What is meant by the statement "Atoms are electrically neutral"?

Answers

Answer:

They have the same number of electrons as protons.

Explanation:

Atoms are electrically neutral means that all the charges within the atom are balance to equal neutral. An atom has the same number of protons as it does electrons, therefore the charge is neutral.

An ion has a different number of electrons than protons, making the ion either positively or negatively charged.

Answer:

Hi! I am currently taking AP Chemistry, I'll try to help you out.

That quote basically just means that the atom as a whole is not positively or negatively charged. Atoms are made up of protons, neutrons, and electrons. Neutrons are neutrally charged. Protons are positively electrically charged. And electrons are negatively electrically charged. In atoms, if there is an even number of protons and electrons, they can cancel each other's charges out, which results in the atom as a whole being electrically neutral.

how do convection currents form ?

Answers

Answer:

Convection currents occur when a fluid is near a heat source.

Explanation:

Heat sources provide energy to their surroundings. When fluid receives this energy, molecules inside it move around more, spacing out from each other and lowering the density.

We know from helium balloons that things with lower densities than their surroundings are pushed upwards. Therefore, the fluid close to the heat source moves upwards, as it is hotter than the rest.

As this fluid moves up, cooler molecules drift down, succumbing to gravity.

As hot molecules move up and further from the heat source, they cool down, and drop. As colder molecules drop and move towards the heat source, they heat up, and begin rising.

This results in a circular motion called a convection current. It is present in the strong winds at the seaside and in the magma in the Earth's mantle.

what role do particles play in exterting pressure?

Answers

Answer:

Pressure is an important physical quantity—it plays an essential role in topics ranging from thermodynamics to solid and fluid mechanics. As a scalar physical quantity (having magnitude but no direction), pressure is defined as the force per unit area applied perpendicular to the surface to which it is applied. Pressure can be expressed in a number of units depending on the context of use.

which contains the most amount of energy a glass of water at 20C or a glass of water at 80C. EXPLAIN ANSWER

Answers

Answer:

80C

Explanation:

As a substance gets hotter, or as a substance gets closer to the state of gas, the particles in the substance move faster, become more spread out and have more energy. This is why Gas has the most energy while solids have the least. Therefore, the hotter a substance is the more energy it has.

A glass of water at 80°C will have the most amount of energy

Explanation:

The temperature is defined as the degree of hotness and coldness of the object.It is a measure of the average kinetic energy of the particles of the object.The hotter the object, the higher will be the kinetic energy of the particles of the object,  higher will be the value of temperature.The colder the object, the lower will be the kinetic energy of the particles of the object, lower will be the value of temperature.

So, from this, we can conclude that glass with water at a higher temperature that is 80°C will have a  higher amount of energy than a glass of water at 20°C.

Answers

the volume is 1,409,725 meters

goes into a calculator and comes out w the given answer

If a large office building is 1.07 x 10^2 meters long, 31 meters wide. and 4.25 x 10^2 meters high, then the volume of the building would be 1409725 meters cube.

What is density?

It can be defined as the mass of any object or body per unit volume of the particular object or body. Generally, it is expressed as in gram per cm³ or kilogram per meter³.

As given in the problem we have to calculate the volume of a large office building having the dimensions of  1.07 x 10 ^2 meters long,  31 meters wide, and 4.25 x 10^2 meters high.

The volume of the office building = length × width × height

                                                        =107 × 31 × 425

                                                        =140925 meters cube

Thus, the volume of the building would be 140925 meters cube.

John Dalton contribute to the understanding of the atom that all matter was composed of atoms, indivisible and indestructible building blocks.

While all atoms of an element were identical, different elements had atoms of differing sizes and mass.

What is an atom?

An atom is a particle of matter that uniquely defines a chemical element.

An atom consists of a central nucleus that is usually surrounded by one or more electrons.

Dalton's atomic theory was the first complete attempt to describe all matter in terms of atoms and their properties.

Dalton based his theory on the law of conservation of mass and the law of constant composition.

The theory states that all matter is made of atoms, which are indivisible.

(1) All matter is composed of tiny, indivisible particles, called atoms, that cannot be destroyed or created.

(2) Each element has atoms that are identical to each other in all of their properties.

The half life of iodine-125 is 60 days. What was the initial amount of iodine-125 if you have 4.5 grams after 360 days?

Answers

Answer:

288 grams

Explanation:

The amount of any radiative substance left after some time is calculated by

amount left = [tex]x/2^n[/tex]

where x is the initial amount of substance

n is the number of half lives

one half live is the time in which amount of substance reduce to half of its initial value.

------------------------------------------------------

amount left = 4.5 grams

half life of  iodine-125 = 60 days

total time in which substance reduced to 4.5 grams  = 360 days

thus,

number of half life in 60 days = 360/60 = 6

thus, there are period of 6 half lives

in each half life the amount of substance reduces to its previous half

let the initial amount be x grams

using the formula

amount left = [tex]x/2^n[/tex]

[tex]4.5 = x/2^6 \\ 4.5 = x/64\\x = 4.5*64 = 288[/tex]

Thus, 288 grams was the initial amount of iodine-125

Heart is a muscular organ which is present in most of the animals , it is responsible for pumping blood via the blood vessels to the entire body.The blood which is pumped carries oxygen and nutrients along with it.Along with it on it's way back to heart it carries carbon dioxide to the lungs.

Heart has an approximate size of a closed fist and is present between the lungs in the middle compartment of the chest. It is divided in to for chambers , the upper chambers called atria and lower ones called ventricles.

The wall of the heart is made up of three layers : epicardium,myocardium and endocardium. It pumps blood with a rhythm which is determined by a group of cells which are called the pacemaker cells present in the sinoatrial node.

If this decay has a half life of 2.60 years, what mass of 72.5 g of sodium 22 will remain after 15.6 years

Answers

Sodium-22 remain : 1.13 g

Further explanation

The atomic nucleus can experience decay into 2 particles or more due to the instability of its atomic nucleus.  

Usually, radioactive elements have an unstable atomic nucleus.  

General formulas used in decay:  

[tex]\large{\boxed{\bold{N_t=N_0(\dfrac{1}{2})^{T/t\frac{1}{2} }}}[/tex]

T = duration of decay  

t 1/2 = half-life  

N₀ = the number of initial radioactive atoms  

Nt = the number of radioactive atoms left after decaying during T time  

half-life = t 1/2=2.6 years

T=15.6 years
