The average velocity of the fly between 0 and 15 seconds will be 10 m/sec.Velocity is the time-based component.

The average velocity is the ratio of the total distance traveled to the total time taken by the body. Its unit is m/sec.

From the given graph it is obsderved that the displacement from 0 to 15 seconds will be 150 m.

[tex]\rm V = \frac{D_2-d_1 }{t_2-t_1} \\\\ V = \frac{150}{15-0} \\\\ V= 10 \ m/sec[/tex]

Answer:

C) The magnitude and direction

Explanation:

Velocity is a vector quantity, meaning that it has both magnitude and direction.

For the momentum, we look at both the direction of the ball (negative, positive) and the magnitude of the velocity (5 m/s, 10 m/s) when figuring out what to use for "v" in p = mv.

Low-mass stars have much longer lifetimes than high-mass stars.

The stars which they should bet on is  D) a star of about 8% the mass of our Sun.

This refers to the astronomical object which is very far away in the galaxy and and of which the closest star to the Earth is in fact the Sun.

With this in mind, we can see that the students are making bets about the time different stars will take to evolve and want to know which star will become a red giant first so they should bet on a star of about 8% the mass of our Sun.

Hi there!

We can begin by deriving an equation for the orbital radius.

For an object orbiting the earth, it is experiencing a centripetal force due to the force of gravitation.

Recall Newton's Law of Universal Gravitation:
[tex]F_g = \frac{Gm_1m_2}{r^2}[/tex]

G = Gravitational Constant (6.67 × 10⁻¹¹ Nm²/kg²)

m = masses (kg)
r = radius (m)

This is equivalent to the satellite's centripetal force experienced:

[tex]F_c = \frac{m_sv^2}{r}[/tex]

[tex]m_s[/tex] = mass of satellite (kg)

v = velocity (m/s)

r = radius (m)

Set the two equal, and rearrange for the orbital radius of the satellite.

[tex]\frac{Gm_sm_p}{r^2} = \frac{m_sv^2}{r}\\\\\frac{Gm_p}{r} = v^2\\\\r = \frac{Gm_p}{v^2}[/tex]

Notice that the orbital radius of the satellite does NOT depend on the satellite's mass. (we canceled it out).

Now, plug in the given values.

[tex]r = \frac{(6.67\times 10^{-11})(6\times 10^{20})}{17000^2} = \boxed{138.478 m}[/tex]

The best answer is true. Yes, control rods are used to slow down the reaction in the reactor core when the core becomes too hot.

A nuclear reactor, often known as an atomic pile, is a device that initiates and controls nuclear chain reactions or nuclear fusion processes.

Nuclear reactors are used in nuclear power plants to generate energy as well as in nuclear marine propulsion.

Control rods are employed in nuclear reactors because the processes that occur in a nuclear reactor are very exothermic.

As a result, when these control rods are infused into a nuclear reactor, they absorb neutrons and aid in the management of the chain reaction. As a result, the rate of the chain reaction is brought under control.

As a result, we may infer that the statement control rods are employed to slow down the reaction in the reactor core when it gets too hot is correct.

Hence the best answer is true. Yes, control rods are used to slow down the reaction in the reactor core when the core becomes too hot.

The triangular crest. shows the resulting wave when they cross at a point x. The meeting point of two waves is known as wave interference ia x.

A wave pulse is a short, non-periodic wave that is formed by a single energy input rather than a continuous or repeated energy input.

Wave interference is the result of multiple waves interacting. There are two types of interference: constructive and destructive.

The relative displacement of the waves is the difference between the two. Wave beats are frequently caused by wave interference.

The distance between the image and the mirror is -8.6 cm

A concave mirror has a reflective surface that is curved inward and away from the light source. Concave mirrors reflect light inward to one focal point.

Unlike convex mirrors, the image formed by a concave mirror shows different image types depending on the distance between the object and the mirror.

Let's use the mirror equation to solve the problem:

[tex]\dfrac{1}{f}=\dfrac{1}{d_o}+\dfrac{1}{d_i}[/tex]

where f is the focal length of the mirror,  the distance of the object from the mirror, and  the distance of the image from the mirror.

For a concave mirror, for the sign convention f is considered to be positive. So we can solve the equation for  by using the numbers given in the text of the problem:

[tex]\dfrac{1}{12}=\dfrac{1}{5}+\dfrac{1}{d_i}[/tex]

[tex]\dfrac{1}{d_i}=-\dfrac{7}{60}[/tex]

[tex]d_i=-8.6\ cm[/tex]

Where the negative sign means that the image is virtual, so it is located behind the mirror, at 8.6 cm from the center of the mirror.

Hence the distance between the image and the mirror is -8.6 cm

The statement 'a distant star gives off a visible range of light whose color depends on its temperature' is supported by the wave model​.

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.
