Which statement best describes the difference between atoms and molecules

Answer:

the kinetic energy decrease is equal to potential energy increase

If the potential energy of pendulum increases then the kinetic energy decreases and if the kinetic energy increases then the potential energy decreases.

According to the work power theorem the total energy of any object will remain constant like the sum of the kinetic and the potential energy of the object will remain constant.

The potential energy of any object is due to its position with respect to the ground. If the object is at a height of H then it will have a potential energy because some energy is given to that object against the gravity to move it to the height H.

The kinetic energy is the energy due to the velocity of the object and is given as the product of half mass to the velocity square.

Now we will express it in the form of the formula for better understanding .

[tex]\rm Total\ energy= KE+PE[/tex]

Now in the pendulum the motion is back and forth with respect to its mean position. So the total energy in the pendulum is the sum of the kinetic energy and the potential energy.

Now if the pendulum attains the maximum displacement from its mean position then it will have maximum potential energy and zero kinetic energy at this point.

Now if the pendulum is at the mean position now it will have maximum kinetic energy and zero potential energy at this point.At this point the potential energy totally converted to the kinetic energy.

Now at the maximum displacement the kinetic energy totally converts into the potential energy of the pendulum.

Thus If the potential energy of pendulum increases then the kinetic energy decreases and if the kinetic energy increases then the potential energy decreases.

Answer:

18

Explanation:  

V = voltage

I = current  

R = resistance  

V = IR is the equation to find out the Voltage of an item so if we move around the equation so we are trying to resistance it would become R = V/I.  

V = IR  

R = V/I  

R = 9/0.5  

R = 18

Answer:

breaking apart of atoms of certain elements to release rays of energy or particles.

Atoms are the building blocks of elements. However, some atoms have an excessive number of neutrons or protons in their nuclei. This causes an imbalance in the forces that keep them together, resulting in an excessive amount of internal energy. These atoms are referred to as radioactive or unstable.

Answer:

770.1 m

Explanation:

From the question given above, the following data were obtained:

Velocity (v) = 45.3 m/s

Time (t) = 17 s

Displacement (d) =?

Velocity is defined according to the following formula:

Velocity = Displacement /Time

With the above formula, we can obtain the displacement of the ball as follow:

Velocity = Displacement /Time

45.3 = Displacement / 17

Cross multiply

Displacement = 45.3 × 17

Displacement = 770.1 m

Therefore the displacement of the ball is 770.1 m

Answer: 770.1     gravity multiplied by time

Answer:

V = 0.87 volt

Explanation:

Given that,

Charge, [tex]q=7.3\times 10^{-17}\ C[/tex]

Electric potential energy, [tex]U=6.4\times 10^{-17}\ J[/tex]

We need to find the value of electric potential at a point. The relation is as follows :

[tex]V=\dfrac{U}{q}[/tex]

Where

V is electric potential

So,

[tex]V=\dfrac{6.4\times 10^{-17}}{7.3\times 10^{-17}}\\\\V=0.87\ V[/tex]

So, the value of the electric potential at a point is equal to 0.87 Volts.

Explanation:

The information tells you about the rate of decay is that in Florida the reaction occurs more slowly when there is less oxygen in the air.

The reduction in the number of radionuclides per unit time is the rate of decay.

The following table shows that the rate of decay only depends upon the level of oxygen. In Florida concentration of the oxygen in the air is high

Due to this the decay time is less.

The decay time is inversly propotional to the rate of decay. In Florida the rate of decay is high.

Hence the information is that reaction occurs more slowly when there is less oxygen in the air.

De acuerdo con el enunciado, el gas experimenta un proceso isotérmico y se conserva su masa. Asumiendo que el gas se comporta idealmente, tenemos la siguiente relación entre los estados final e inicial:

[tex]P_{1}\cdot V_{1} = P_{2}\cdot V_{2}[/tex] (1)

Donde:

[tex]P_{1}, P_{2}[/tex] - Presiones inicial y final, medidos en atmósferas.

[tex]V_{1}, V_{2}[/tex] - Volúmenes inicial y final, medidos en litros.

Si sabemos que [tex]P_{1} = 10\,atm[/tex], [tex]P_{2} = 1\,atm[/tex] y [tex]V_{2} = 20\,L[/tex], entonces el volumen inicial del gas es:

[tex]V_{1} = \frac{P_{2}\cdot V_{2}}{P_{1}}[/tex]

Answer: The infra red waves is located between microwave and visible light based on their WAVELENGTH and FREQUENCY of occurrence.

Explanation:

Electromagnetic waves are those waves that do not require or need a material medium for its propagation, but they are able to travel through a vacuum. They exhibit or show all properties associated or connected with light. They are undeflected in electric and magnetic fields. These electromagnetic waves are arranged in order of their FREQUENCY and WAVELENGTHS which is known as ELECTROMAGNETIC SPECTRUM.

FREQUENCY is defined as the number of cycles which the wave completes in one second and is measured in Hertz(Hz). While WAVELENGTH is defined as the distance between two successive crests or troughs of waves which is measured in meter (m).

The electromagnetic spectrum is made up of the following rays which is arranged from the biggest wavelengths to the smallest:

--> Radiowaves

--> microwave :

--> infrared rays:

--> visible light:

--> ultraviolet rays

--> x-rays and

--> Gamma rays.

According to the arrangement of the spectrum above, the microwave has a higher wavelength and frequency than the infrared rays, while the visible light has a lower wavelength and frequency than the infrared rays.
