A liquid thermometer can be used to test for fevers. When body temperature increases, the liquid inside the thermometer expands

and
rises to show a higher
temperature reading. Which of the following explanations best describes the changes in thermal energy of the
particles during this specific example of heat transfer?
A. The tip of the thermometer is heated by radiation from the person's body. The particles of the thermometer tip then transfer heat
by convection through the liquid inside of it. The particles inside the liquid then convect heat causing the warmer particles to slow
down, rise, and expand.
B. The tip of the thermometer is heated by conduction from the person's body. The particles of the thermometer tip then transfer heat
by convection through the liquid inside of it. The particles inside the liquid then convect heat causing the warmer particles to slow
down, rise, and expand.
© C. The tip of the thermometer is heated by convection with the person's body. The particles of the thermometer tip then transfer heat
by conduction with the liquid inside of it. The particles inside the liquid then conduct heat causing the warmer particles to speed up,
rise, and expand
© D The tip of the thermometer is heated by conduction with the person's body. The particles of the thermometer tip then transfer heat
by conduction with the liquid inside of it. The particles inside the liquid then convect heat causing the warmer particles to speed up,
rise, and expand

Answer:

Hope this helped :

Explanation:

When light passes from a medium with one index of refraction (m1) to another medium with a lower index of refraction (m2), it bends or refracts away from an imaginary line perpendicular to the surface (normal line). As the angle of the beam through m1 becomes greater with respect to the normal line, the refracted light through m2 bends further away from the line.

At one particular angle (critical angle), the refracted light will not go into m2, but instead will travel along the surface between the two media (sine [critical angle] = n2/n1 where n1 and n2 are the indices of refraction [n1 is greater than n2]). If the beam through m1 is greater than the critical angle, then the refracted beam will be reflected entirely back into m1 (total internal reflection), even though m2 may be transparent!

Explain what happens inside the radiation zone that causes the photon to take so long to exit the sun
DaniilM [7]
-A photon travels, on average, a particular distance, d, before being briefly absorbed and released by an atom, which scatters it in a new random direction.

-Given d and the speed of light, c, you can figure out the average time step and space step size (how often the photon “steps” and how far it “steps” each time).

-The size of the Sun is figured in terms of step size. Some surprisingly tricky math happens, involving “Brownian motion” and probabilities. Finally,

-The average time it would take to get to the surface of the Sun is found.

Find the following answer based on the image.
saul85 [17]

<u>We are given:</u>

Mass of Neptune = 1.03 * 10²⁶ kg

Distance from the center of Neptune (r) = 2.27 * 10⁷

now, computing the value of the acceleration due to gravity (g)

<u>Finding g:</u>

We know the formula:

g = G(mass of planet) / (r)²

g = [6.67 * 10⁻¹¹ * 1.03*10²⁶] / (2.27*10⁷)                      [since G is 6.67*10⁻¹¹]

g = (6.87 * 10¹⁵) / (5.15 * 10¹⁴)

which can be rewritten as:

g = (6.87 * 10¹⁵ * 10⁻¹⁴) / 5.15

g = (6.87 * 10¹⁵⁻¹⁴) / 5.15

g = (6.87/5.15) * 10

g = 1.34 * 10

g = 13.4 m/s² <em>(approx)</em>

What unit is used for the value of G in Newton's Law of Universal<br> Gravitation?<br> *
Helga [31]

Answer:

In SI units, its value is approximately 6.674×10−11 m3⋅kg−1⋅s−2. The modern notation of Newton's law involving G was introduced in the 1890s by C. V. Boys. The first implicit measurement with an accuracy within about 1% is attributed to Henry Cavendish in a 1798 experiment.
