The presence of potential energy between particles supports the shape of a heating curve.

<h2>Potential energy and heating curve</h2>

The existence of potential energy between particles supports the shape of a heating curve because potential energy causes the heating curve flat as well as in curve form. The heating curves show how the temperature changes as a substance is heated up.

The potential energy of the molecules will increase anytime energy is being supplied to the system but the temperature is not increasing so when the heating curve go flat it means there is potential energy so we can conclude that the existence of potential energy between particles supports the shape of a heating curve.

Pls pls pls pls help!!!!!

Answer:

The net upward force the man experiences is approximately 1,324.8 N

The net downward force the man experienced is approximately 556.8 N

Explanation:

The given mass of the man, m = 96 kg

The acceleration of the elevator, a = 4.0 m/s²

According to Newton's third law of motion which states that action ad reaction are equal and opposite, when the elevator moves upwards, we have;

The net force the man experiences, F = Gravitational force, m·g + The force of the elevator pushing upwards, m·a

∴ ↑F = m·g + m·a

Where;

F = The net force the man experiences

m = The mass of the man = 96 kg

g = The acceleration due to gravity ≈ 9.8 m/s²

a = The acceleration of the elevator = 4 m/s²

∴ ↑F = 96 kg × 9.8 m/s² + 96 kg × 4 m/s² ≈ 1,324.8 N

The net upward force the man experiences ≈ 1,324.8 N

When the elevator moves downwards, we have;

The net force the man experiences, F = Gravitational force, m·g + The loss of the gravitational force as the floor moves further downwards, -(m·a)

∴ F = m·g + -(m·a) = m·g - m·a

F = m·g - m·a

∴ ↓F = 96 kg × 9.8 m/s² - 96 k × 4 m/s² ≈ 556.8 N

The net downward force the man experienced ≈ 556.8 N

The figure shows five electric charges. Four charges with the magnitude of the charge 2.0 nC form a square with the size a = 4.0

bearhunter [10]

Considering the four electric charges forming a square with magnitude of charge of 2.0 nC on each. :

A) Magnitude of the force on the 5.5 nC charge in the middle of the figure = 3.48 * 10^-4 N

B) Direction of the force on the 5.5 nC charge in the middle of the figure = Leftward ( negative x -axis )

Using the given data :

size of square = 4 cm

magnitudes of four charges = 2.0 nC

<u> a) </u><u>magnitude</u><u> of the force on the center charge </u>

Electric force between two point charges = $F = \frac{1}{4\pi *E_{o} } \frac{q1q2}{r^2}$ ----- ( 1 )

where ; $\frac{1}{4\pi E_{o} } = 9 * 10^9 Nm^2/C^2$

step 1 ; find r ( distance between charges )

r² = ( 2 )² + ( 2 )² = 8 cm²

back to equation 1

F = 9 * 10⁹ * $\frac{2 * 10^{-9} * (5.5 * 10^{-9}) }{8*10^{-4} }$ = 1.23 * 10^-4 N

∴ magnitude of the force on the center charge ( Fnet )= 4F cos 45°

= 4 * ( 1.23 * 10^-4 ) * $\frac{1}{\sqrt{2} }$ = 3.48 * 10^-4 N

b) The direction of the force at the center is along the negative x-axis ( leftward )

Which sequence shows all the spectral colors of the visible light arranged in a decreasing order of their wavelength?

Ad libitum [116K]

Correct answer choice is :

B) Red, orange, yellow, green, blue, indigo, and violet

Explanation:

A spectral color is a color that is extracted in a natural human by a single wavelength of light in the apparent rainbow, or by a comparatively narrow band of wavelengths, also recognized as monochromatic light. The combination of colors provided when the light is separated by a prism. Spectrum an indexed order of the elements of an radiation or wave. Electromagnetic rainbow the complete wavelength spectrum of electromagnetic waves.
