The statement 'a distant star gives off a visible range of light whose color depends on its temperature' is supported by the wave model.
<h3>What is wavelength?</h3>
The wavelength can be defined as the periodic distance of a given wave that repeats in a constant way.
The emissivity of particles is a function of both wavelength and temperature of a given material/object. Visible wavelengths range from 700 nm to 400 nm (violet color).
Star temperature largely determines its color, blue stars are warmer than yellow and red stars, and red stars are cooler than yellow stars.

Using geometrical arguments, we can see that the angle of the inclined plane

is equal to the angle between Fg and the perpendicular force.
But the perpendicular force is the projection of Fg along the perpendicular axis, and Fg=mg, so the correct answer is
<span>C) F=mg cosΘ </span>
The design of rutherfords experiment show what he was trying to find out is by detect charged particles. He shot positively charged alpha particles at foil containing gold atoms, what they did showed what was in them neutrons etc Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
Answer:
Options (C) and (F).
Explanation:
Constant speed of an object is represented by the flat segment (a line parallel to the x-axis) on the graph of velocity and time.
In other words, flat segments represents no change in the velocity with respect to the time.
From the graph attached,
Being flat segments, C and F will represent the constant speed.
Therefore, Options (C) and (F) will be the correct options.
Answer:
Approximately
and approximately
.
Explanation:
Let
and
denote the capacitance of these two capacitors.
When these two capacitors are connected in parallel, the combined capacitance will be the sum of
and
. (Think about how connecting these two capacitors in parallel is like adding to the total area of the capacitor plates. That would allow a greater amount of charge to be stored.)
.
On the other hand, when these two capacitors are connected in series, the combined capacitance should satisfy:
.
(Consider how connecting these two capacitors in series is similar to increasing the distance between the capacitor plates. The strength of the electric field (
) between these plates will become smaller. That translates to a smaller capacitance if the amount of charge stored
stays the same.)
The question states that:
, and
.
Let the capacitance of these two capacitors be
and
. The two equations will become:
.
From the first equation:
.
Hence, the
in the second equation here can be replaced with
. That equation would then become:
.
Solve for
:
.
.
.
Solve this quadratic equation for
:
or
.
Substitute back into the equation
for
:
In other words, these two capacitors have only one possible set of capacitances (even though the previous quadratic equation gave two distinct real roots.) The capacitances of the two capacitors would be approximately
and approximately
(both values are rounded to two significant digits.)
