Each of the eight planets in the Solar System follows a different elliptical orbit around the Sun. An ellipse is a type of oval shape. Each planet's orbit is at a different distance from the Sun than the other planets' orbits.

Beginning nearest to the Sun, the order of the planets is: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.

Based on this order, which of the following is true of Mercury?
A.
It must travel farther than Earth does to complete one orbit around the Sun.
B.
It travels a shorter distance than Earth does to complete one orbit around the Sun.
C.
It travels the same distance as Earth does to complete one orbit around the Sun.
D.
It must travel in the opposite direction around the Sun than Earth does.

Answers

Answer 1

Answer:

It must travel farther than Earth does to complete one orbit around the Sun.

Explanation:

Each planet orbits around the Sun along an elliptical path. The farther away from the Sun a planet is, the larger the ellipse. The larger the ellipse, the longer the distance around it. Because the orbit of Mars is larger than the orbit of Earth, Mars must travel farther than Earth does to complete one orbit around the Sun.

Answer 2

Mercury travels a shorter distance than Earth does to complete one orbit around the Sun.

Based on the positions of the 8 planets from the sun, Mercury is closest to the sun. The implies that the distance of Mercury from sun is very short when compared to Earth or other planets.

The shorter the distance, the shorter time it would require to make a complete orbit around the sun.

For instance;

It takes Mercury about 88 days to make a complete orbit around the sunIt takes Earth about 365 days to make a complete orbit around the sun

Thus, we can conclude that Mercury travels a shorter distance than Earth does to complete one orbit around the Sun.

Which segment of this graph shows a decreasing velocity?

A. A to B
B. B to C
C. C to D
D. D to E
E. E to F

Answers

Answer:

E to F

Explanation:

The velocity decreases during segment E to F since the slope of the curve decreases with time.

Position-time graph:

We have 5 segments in the given graph between position and time. Analyzing each segment we can conclude the following:

Segment A to B: the position remains constant as time increases, this means that the velocity is zero.

Segment B to C: the rate of increase in the position slowly becomes greater as time passes, which means velocity is increasing and the object is accelerating

Segment C to D: The rate of increase in the position is constant with respect to the rate of increase in time, the slope of the curve is constant, which means that the velocity is constant.

Segment D to E: same as the segment A to B, the velocity is zero.

Segment E to F: The rate of increase in the position slowly decreases with time, and the slope of the curve decreases with time, which means the velocity is decreasing.

A spring compresses 0.8 m when the 800 kg crate of llamas slides down and hits it. Ignore friction and find the spring constant of the spring. The ramp is at a 47° angle.

Answers

Answer:

7167.27N/m

Explanation:

To get the force constant k, we will use the formula;

F = kx where

F is the force acting on the object down the plane

k is the spring constant

x is the extension

The force acting down the ramp us F = Wsintheta. The formula will become;

Wsintheta = kx

mgsintheta = kx

K = mgsintheta/x

K = (800)(9.8)sin47°/0.8

K= 7840sin47°/0.8

K = 5733.81/0.8

K = 7167.27N/m

Hence the spring constant of the spring is 7167.27N/m

At which position is the roller coaster car's amount of potential energy about equal to the amount of kinetic energy?​

Answers

It will be potential because the roller coaster is going down so it’s not giving off energy to the roller coaster.

Answer:

The mass of the cars and people and the height of the track where the cars are located determine the potential energy in the system. Potential energy depends on an object’s mass and height and the gravitational pull on the object. A change in gravity would result in a change in potential energy. For example, if the track were located on the Moon instead of Earth, the potential energy would be different.

Are three coefficients of expansion alpha bita and gamma universal constant?​

Answers

Answer:

As the temperature increases, the volume of the material also increases. This is known as thermal expansion. It can also be explained as the fractional change in the length or volume per unit change in the temperature.

The relation between alpha, beta, and gamma is given in the form of a ratio and the ratio is 1:2:3 and can be expressed as:

alpha=fracbeta2=fracgamma3

Following is the relation between the three:

L = L (1 + α.ΔT)

Where, α is the coefficient of linear expansion  

A = A (1 + β.ΔT)

Where, β is the coefficient of aerial expansion

V = V (1 + γ.ΔT)

Where, γ is the coefficient of cubical expansion  

V = V + γV.ΔT

V = V (1 + γ.ΔT)  

L3 = L3 (1 + α.ΔT)3

L3 = L3 (1 + 3α.ΔT + 3α2.ΔT2 + α3.ΔT3)

L3 = L3 (1 + 3α.ΔT)

Alpha, beta, and gamma are related to one another in the form of a ratio, and that ratio is 1:2:3, and yes they are universal constants.

What is expansion?

A substance's volume expands while its mass stays constant. Heating is typically the cause of expansion. When a substance is heated, the molecular bonds separating its particles weaken, the particles move more quickly, and the substance expands as a result.

Determine the relation as shown below,

L = L (1 + α × Δ T)

here, α is the coefficient of linear expansion  

A = A (1 + β × Δ T)

here, β is the coefficient of aerial expansion

V = V (1 + γ × Δ T)

here, γ is the coefficient of cubical expansion  

V = V + γ × V × Δ T

V = V (1 + γ × ΔT)  

L3 = L3 (1 + α × Δ T)3

L3 = L3 (1 + 3α × ΔT + 3α2 × ΔT2 + α3 × ΔT3)

L3 = L3 (1 + 3α × Δ T)

Clouds are forming along the front because the rising air is
A) contracting and warming, causing
evaporation
B) contracting and cooling, causing evaporation
C) expanding and warming, causing condensation
D) expanding and cooling, causing condensation

Answers

Answer:

D

Explanation:

The water vapor rises in the air.  It starts to expand while cooling the higher it gets in the atmosphere. This causes condensation.

Clouds are forming along the front because the rising air is expanding and cooling, causing condensation (Option D).

Cloud formation occurs when water vapor cools and condenses to form liquid water droplets or solid ice crystals.

In a cloud, liquid water droplets are formed at temperatures higher than 0 Celsius degrees, while solid ice crystals are formed at temperatures lesser than 0 Celsius degrees.

In consequence, during cloud formation, the excess amount changes from water vapor (gas) into a liquid (water droplets) or solid (ice).

In conclusion, clouds are forming along the front because the rising air is expanding and cooling, causing condensation (Option D).

The current flowing in both the circuits is the same. (a) Will the heat produced in both the cases be equal? Explain.

Answers

Given :

Reem took a wire of length 10 cm. Her friend Nain took a wire of 5 cm of the same material and thickness both of them connected with wires as shown in the circuit given in figure. The current flowing in both the circuits is the same.

To Find :

Will the heat produced in both the cases be equal.

Solution :

Heat released is given by :

H = i²Rt

Here, R is resistance and is given by :

[tex]R = \dfrac{\rho L}{A}[/tex]

So,

[tex]H = i^2\times \dfrac{\rho L}{A} t\\\\H = \dfrac{i^2\rho Lt}{A}[/tex]

Now, in the question every thing is constant except for the length of the wire and from above equation heat is directly proportional to the length of the wire.

So, heat produced by Reem's wire is more than Nain one.

Hence, this is the required solution.
