The most significant change in the comet's energy as it moves from point D to point A KE increases, GPE decreases.Option C is correct.

<h3>What are comets?</h3>

Comets are frozen leftovers from the formation of the solar system composed of dust, rock, and ice.

They range from a few miles to tens of miles wide, but as they orbit closer to the Sun, they heat up and spew gases and dust into a glowing head that can be larger than a plane.

As the comet transitions from point D to point A, the biggest energy shift is seen. GPE declines as KE rises. The right answer is C.

Hence option C is correct.

Calculate the speed of an object that tavels 62.43m in 38.4s

TiliK225 [7]

The speed of the object can be calculated using the formula:

Speed = distance/time

The given values are:
distance = 62.43 m
time = 38.4 s

Solution:

speed = 62.43 m / 38.4 s = 1.63 m/s

Therefore, the speed of an object that travels 62.43m in 38.4s is <span> 1.63 m/s.</span>

According to Kepler's third law (p2 = a3), how does a planet's mass affect its orbit around the Sun? Group of answer choices

anyanavicka [17]

Answer:

A planet's mass has no effect on its orbit around the Sun.

Explanation:

The kepler's third law tells us:

$p^2=a^3$

where $p$ is the orbit period and $a$ is the semi-major axis.

As we can see from the equation, the period depends only on the measure of the semi-major axis $a$ of the orbit, that is, how far a planet is from the sun.

The equation tells us that the closer a planet is to the sun, the faster it will go around it.

The mass does not appear in the equation to calculate the period.

This is why it is concluded from the third law of Kepler that<u> the period, or the orbit of a planet around the sun, does not depend on its mass.</u>

the answer i: A planet's mass has no effect on its orbit around the Sun.

How to find aceleration

lions [1.4K]

Answer:

$a=\frac{v_{f}-v_{i}}{t_{f}-t_{i}}$

Explanation:

Formula for AVERAGE acceleration

$a=\frac{v_{f}-v_{i}}{t_{f}-t_{i}}$

$v_{f}$ is Final Velocity

$v_{i}$ is Initial Velocity

$t_{f}$ is Final Time

$t_{i}$ is Initial Time

Most of the time, the initial time will be 0, so you won't have to subtract.

5.610^-26 m is closest to the wavelength of the light.

E=K.E - Work function

hc/λ=1.10-4.65

hc/λ=3.50

λ=hc/3.50

λ=6.626×10 −34J⋅s×3×10^8

λ=5.610^-26 m

Because the relationship between wave frequency and wavelength is inverse, gamma rays have extremely short wavelengths that are only a fraction of the size of atoms, whereas other wavelengths can reach as far as the universe. Regardless of the medium they travel through, electromagnetic radiation's wavelengths are typically expressed in terms of the vacuum wavelength, even though this isn't always stated explicitly.

The wavelength of electromagnetic radiation affects its behavior. The speed of light is equal to wavelength times frequency. Frequency multiplied by the Planck constant equals energy. 1/wavelength is the wave number in cm. Along with the wavelengths of different parts of the electromagnetic spectrum, a rough estimation of the wavelength size is displayed.
