the period of the earth around the sun is 1 year and its distance is 150 million km from the sun. an asteroid in a circular orbit around the sun is at a distance 295 million km from the sun. what is the period of the asteroid’s orbit? answer in units of year.

Answers

Answer 1

According to the given statement The asteroid's orbital period is 2.74 years.

Does an asteroid have an orbit?

Asteroids are tiny, rocky bodies that revolve around the Sun. Asteroids are far tiny than planets, although orbiting the Sun in a manner comparable to planets. There are many asteroids in our solar system. The major asteroid belt, which lies between Mars' and Uranus orbits, is where the majority of them have been located.

Briefing:

T1 = 1 year

r1 = 150 million km

r2 = 440 million km

Let T2 be the asteroid's orbital period.

Use Kepler's third law

T² ∝ r³

So,

(T₂ / T₁)² = (r₂ / r₁)³

(T₂ / 1)² = (295 / 150)³

T2 = 2.74 years

Therefore, the asteroid's orbital period is 2.74 years.

calculate the magnitude of the centripetal force acting on earth as it orbits the sun

Answers

The magnitude of the centripetal force acting on Earth as it orbits the Sun can be calculated using Newton's law of universal gravitation and the principles of circular motion.

According to Newton's law of universal gravitation, the force of gravity between two objects is given by the equation F = G * (m1 * m2) / r^2, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between their centers of mass.

In the case of Earth orbiting the Sun, Earth's mass (m1) is much smaller than the Sun's mass (m2), so we can consider Earth as the smaller mass. The centripetal force acting on Earth is provided by the gravitational force between Earth and the Sun.

The centripetal force can be expressed as Fc = m1 * (v^2) / r, where m1 is the mass of Earth, v is the velocity of Earth in its orbit, and r is the distance between the centers of Earth and the Sun.

Since the centripetal force is provided by the gravitational force, we can equate the two equations: Fc = F. Therefore, m1 * (v^2) / r = G * (m1 * m2) / r^2.

Simplifying the equation, we find that (v^2) / r = G * m2 / r^2.

The magnitude of the centripetal force can be obtained by rearranging the equation as Fc = m1 * (v^2) / r = (m1 * G * m2) / r^2.

Therefore, the magnitude of the centripetal force acting on Earth as it orbits the Sun is given by (m1 * G * m2) / r^2, where m1 is the mass of Earth, m2 is the mass of the Sun, G is the gravitational constant, and r is the distance between their centers.

Answers

The weight density of water is 62.4 pounds per cubic foot. This value is used to determine the weight of water based on its volume.

The weight density of a substance is a measure of how much weight it has per unit volume. In the case of water, its weight density is 62.4 pounds per cubic foot. This means that for every cubic foot of water, it will weigh 62.4 pounds.

Weight density is an important concept in various fields, such as engineering, construction, and fluid mechanics. It allows us to calculate the weight of water in different scenarios. For example, if we have a tank with a known volume of water, we can use the weight density to determine the total weight of the water in the tank. Similarly, if we know the weight of water in a container, we can calculate its volume by dividing the weight by the weight density.

Understanding the weight density of water is crucial for various practical applications. It helps in designing structures that involve water, such as dams, reservoirs, and pipes, as it provides insights into the forces exerted by the water. Additionally, it is also relevant in fields like hydrology and environmental science, where accurate measurements of water weight are necessary for calculations and analysis.

2. Amy runs exactly 2 laps around a 400 meter track. What is her distance and displacement?

Answers

Amy's distance is 800 meters since she runs 2 laps around the 400 meter track. Her displacement is 0 meters because displacement refers to the change in position from the starting point to the end point, and since she ends up back where she started, the displacement is zero.

Distance refers to the total length covered in a particular path, regardless of direction or position. Amy runs 2 laps, and each lap is 400 meters, so her total distance is 800 meters (400 meters per lap multiplied by 2 laps).

Displacement, on the other hand, refers to the change in position from the starting point to the end point. Since Amy ends up back at the starting point after completing her 2 laps, her displacement is zero. Displacement takes into account direction and position, and in this case, there is no net change in position from the start to the end, resulting in a displacement of zero.

Answers

Crash of two vehicles that are moving directly toward each other

What is the final speed?

This is a difficulty with momentum conservation. Each cart has a starting momentum equal to its mass multiplied by its velocity. When they hit and stick together, they become a single unit of combined mass of 4 kg + 5 kg, and their new velocity must account for momentum conservation.

Assume the 4 kilogram cart is coming from the left and the 5 kg cart is coming from the right. This results in a velocity of +12 m/s for the 4 kg cart and a velocity of -9 m/s for the 5 weight cart.

The carts’ early moments are

(4 kg * 12 m/s) = 48 kg * m/s

And

-45 (kg * m)/s = (5 kg * -9 m/s)

Answer:

When several resistors are connected in series, the total resistance equals the sum of the individual resistors. In series combination, the current is same through each resistor.

1)   V=  60 volt

Total resistance R = R₁ + R₂

                              = 20 + 10

                              = 30 Ω

2) Ohms law states that,

3) Voltage around 10 Ω resistor,

          V₂ = I R₂

             = 2 * 10

                   = 2 volt

7) Resistance 2:

        Total resistance = R

        Total voltage = V = 8 volt

        Total current = I = 1 A

                  R = 8 Ω

               R₁ + R₂ = 8 Ω

                2 + R₂ = 8

                      R₂  = 8 - 2

13) Voltage at each resistor:

           V₁ = I*R₁

               = 0.75 * 8

               = 6 volt

         V₂ = I*R₂

Explain why the question "Put these bodies in order of

"bad" question to ask on an exam?

Answers

The question "Put these bodies in order of increasing size (black hole, neutron star, white dwarf):" is a "bad" question to ask on an exam because the size of a black hole cannot be measured.

The question provides three celestial bodies and asked to arrange them according to their size. The first problem is with the black hole. The black hole is a celestial body that has infinite density and zero volume, which implies that it does not have a size. Thus, it is impossible to compare the sizes of black holes with other celestial bodies.

The second problem is that the sizes of white dwarfs and neutron stars are hard to measure accurately. It is almost impossible to compare the sizes of celestial bodies in the universe since the universe contains many celestial bodies of various sizes. Thus, the question should have been modified to make it less vague and less difficult. The better way to ask the question might have been "Put these celestial bodies in order of increasing mass."

with what tension must a rope with length 2.10 m and mass 0.110 kg be stretched for transverse waves of frequency 36.0 hz to have a wavelength of 0.760 m ?

Answers

To find the tension in the rope, we can use the equation: v = fλ, where v is the speed of the wave, f is the frequency, and λ is the wavelength.

The speed of a wave on a rope is given by: v = √(T/μ), where T is the tension in the rope and μ is the mass per unit length of the rope.
We can rearrange this equation to solve for T: T = μv^2
Substituting the expression for v from the first equation, we get:
T = μ(fλ)^2
Plugging in the given values, we get:
T = (0.110 kg / 2.10 m)(36.0 Hz)(0.760 m)^2
T = 37.5 N
Therefore, the tension in the rope must be 37.5 N for transverse waves of frequency 36.0 Hz to have a wavelength of 0.760 m.

The greatest number of galaxies belong to the type known as elliptical galaxies.a. Trueb. False

Answers

False. The greatest number of galaxies do not belong to the type known as elliptical galaxies. In fact, the most common type of galaxy in the universe is the spiral galaxy.

Spiral galaxies are characterized by their distinctive spiral arms, which contain young stars, gas, and dust. These galaxies have a central bulge and a rotating disk. Examples of spiral galaxies include our own Milky Way galaxy and the Andromeda galaxy.

Elliptical galaxies, on the other hand, have a more rounded or elliptical shape and lack the prominent spiral arms. They are often reddish in color and have older populations of stars. Elliptical galaxies are typically found in galaxy clusters and are thought to have formed through galaxy mergers and interactions.

While elliptical galaxies are still abundant in the universe, they are not the most numerous type. Studies and observations have shown that spiral galaxies outnumber elliptical galaxies by a significant margin. This is supported by surveys and statistical analyses of large samples of galaxies in different regions of the universe.

The distribution and abundance of galaxy types can provide valuable insights into the formation and evolution of galaxies over cosmic time. Understanding the prevalence of different galaxy types helps astronomers piece together the story of how galaxies form, grow, and interact with their environments.

A car starts from rest and undergoes an acceleration of 7.2 m/s² for a duration of 4.5 seconds. The objective is to determine the velocity of the car at the end of this time.

Velocity of the car at the end of the given time, we can use the equation of motion that relates initial velocity, acceleration, and time:

final velocity = initial velocity + (acceleration × time)

Since the car starts from rest (initial velocity = 0), the equation simplifies to:

final velocity = acceleration × time

Plugging in the given values, we have:

final velocity = 7.2 m/s² × 4.5 s

Calculating the expression, we find:
