smallest: E1>E3>E5> maximum: E7 (b) most: spiral > elliptical least: inconsistent, An object is said to be rotating in an elliptical orbit when it follows an oval-shaped path around another object.

An elliptical orbit can be advantageous for communications satellites because it allows the satellite to pass over a certain area for a significant amount of its orbit and only briefly loses contact with it when it is whizzing swiftly around the opposite side of the Earth.

The item will eventually be moving slowly enough to be drawn back in as a result of this somewhat wider orbit slowing down the orbital speed. In turn, this causes the object's separation from its parent to fluctuate, creating an elliptical orbit.

Explanation:

Answer: Ridges form along cracks (divergent boundaries) in the oceanic crust (Molten rock (magma) rises through these cracks and pushes to both sides. When it cools, it forms new oceanic crust. The old crust is pushed away and new crust takes over. This is called Sea-Floor Spreading.

The power drain of the system will be 369.8 times the drain current square.

To find the answer, we have to know about the effective resistance.

                       \(P_d=I_d^{2}R\)

where;     \(I_d\) is the drain current and R is the effective resistance of the circuit.

              \(R=(\frac{R_1R_2}{R_1+R_2} )+R_3\)

where, R1=220ohm, R2=470ohm and R3=220ohm.

                 \(R=369.8Ohm\)

                        \(P_d=(369.8I^2 )Watt\)

Thus, we can conclude that, the power drain of the system will be 369.8 times the drain current square.

Approximately 1580 wavelengths of a helium-neon laser are equivalent to 1.0mm.

a. To correctly describe the interactions of light with objects, we must use a wave model for objects with sizes comparable to or smaller than the wavelength of the light. This is typically in the range of nanometers (10^-9 meters).
b. To determine how many wavelengths of a helium-neon laser are equivalent to 1.0mm, we'll convert 1.0mm to nanometers and then divide by the wavelength of the laser. The helium-neon (He-Ne) laser is known for emitting laser light at specific wavelengths. The two most common wavelengths emitted by a He-Ne laser are 632.8 nanometers (nm) and 543.5 nm.
1.0mm = 1,000,000nm
Now, we'll divide by the wavelength of the helium-neon laser (632.8nm):
1,000,000nm / 632.8nm ≈ 1580 wavelengths

If a cube of iron, 0.0800 m on a side, has a density of 7874 kg/m³, the mass of the iron cube is 4.03 kg.

To find the mass of the iron cube, we need to use the formula:

density = mass / volume

Rearranging the formula to solve for mass, we get:

mass = density x volume

The volume of the cube can be calculated as:

volume = side³

Substituting the given values, we get:

volume = (0.0800 m)³ = 5.12 x 10^-4 m³

Now we can calculate the mass of the cube:

mass = density x volume
mass = 7874 kg/m³ x 5.12 x 10^-4 m³
mass = 4.03 kg

Therefore, the mass of the iron cube is 4.03 kg.

Since the drag force is proportional to the square of speed,  to improve your car’s gas mileage, you should drive in lower speed.

The drag force is a force experienced by an object when it is moving through a fluid. The fluid can be air, water, gas or liquid.

Some of the factors that affect the drag force are the speed of the object and its aerodynamic. The relation between drag force and velocity is given by:

F = 1/2 . CρAv²

Where:

C = drag coefficient

ρ = fluid density

A = area of the object that facing the fluid

v = velocity

Therefore, the drag force is directly proportional to the square of object's velocity, or

F ∝ v²

The power of car should overcome this drag force. The relation between power and force is given by:

P = F . v

Since F is proportional to v², then

P ∝ v³

Thus, we can conclude to use less power, which means to improve gas mileage, you should drive in lower speed.

The negatively charged van de Graff generator can make a flow of electrons through the tape and these both will repel each other. When the tape comes in contact with the balloon, the positive charges of balloon gets attracted and they stick together.

Electrons are drawn from the earth by a Van de Graaff generator, transported via a belt, and then stored on the big sphere. These electrons are attracted to one another and try to distance themselves from one another by dispersing throughout the surface of the sphere.

Electrons can spread out widely on the earth, thus they will choose the shortest route possible to return to the ground. The electrons from the tape repel the electron from the tape, make the tape negatively charged.

This negatively charged tape when comes in contact with the balloon, it will polarize the balloon and its positive charges aligns with the tape's charge and gets stuck.

A brass cube with a side measurement of 10 cm increases in volume by 22.5% when the temperature is increased by 200°C. Brass has a volume expansion coefficient of 57x10-6/oc.

A device's ability to enable fluid flow is relative measured by the flow coefficient of volume of the device. In more concrete terms, the flow coefficient Cv is the amount of water (measured in US gallons) that will pass through a valve at 60 °F and a pressure drop of 1 psi per minute. The concept of temperature is used to convey quantitatively how hot and cold something is. Using a thermometer, one can gauge temperature. Thermometers are calibrated using different temperature scales that traditionally relied on different reference points and thermometric materials for definition.

Given:

length of the cube, l = 10cm

change in temperature of the cube, T = 200

coefficient of volume expansion, beta = 57*10^-6

delta L = delta L/L *100

delta L = 0.0225/0.1 *100

Multiply the length, width and height of the brick to calculate its volume.

Explanation:

To find the volume of a rectangular brick, you need to multiply its length, width, and height.

The rectangular brick is 400 cubic centimeters (cm³).

The formula to calculate the volume of a rectangular prism (which includes a rectangular brick) is:

\(\[ \text{Volume} = \text{Length} \times \text{Width} \times \text{Height} \]\)

Let's assume the length of the rectangular brick is 10 cm, the width is 5 cm, and the height is 8 cm. Plugging these values into the formula, we get:

\(\[ \text{Volume} = 10 \, \text{cm} \times 5 \, \text{cm} \times 8 \, \text{cm} \]\)

Now we can calculate the volume:

\(\[ \text{Volume} = 400 \, \text{cm}^3 \]\)

Therefore, the volume of the rectangular brick is 400 cubic centimeters (cm³).

The change of displacement with respect to time is defined as the velocity.  Velocity is a vector quantity.

it is a time-based component. Velocity at any angle is resolved to get its component of x and y-direction.

Explanation:

formation of compounds because the electric forces compel the atoms to attract each other and formed bonds which leads to the formation of chemical compounds. The attractive or repulsive interaction between any two charged bodies is known as an electric force so the attraction between two opposite charged atoms causes the formation of compounds so we can conclude that electric forces are important for the formation of compounds.

In many ways, an electric circuit is like the plumbing system in a home. The voltage on an electric circuit corresponds to the pressure in a plumbing system.

Just as water flows from a high-pressure area to a low-pressure area in a plumbing system, current flows from a high-voltage area to a low-voltage area in an electric circuit.

Similarly, just as pipes in a plumbing system can be thought of as resistors that limit the flow of water, resistors in an electric circuit limit the flow of current.

The flow rate of water in a pipe is determined by the pressure difference across the pipe and the resistance of the pipe. Similarly, the flow of current in a resistor is determined by the voltage difference across the resistor and the resistance of the resistor.

The usual symbols used for the following properties of a star are:

- Brightness: Usually represented by the symbol "B" or "m". It refers to the amount of light received from a star as observed from a particular location.

- Luminosity: Represented by the symbol "L". It refers to the total amount of energy radiated by a star per unit of time.

- Apparent Magnitude: Represented by the symbol "m". It is a measure of the brightness of a star as observed from Earth. Lower values indicate brighter stars.

- Absolute Magnitude: Also represented by the symbol "m". It is the intrinsic brightness of a star, defined as the apparent magnitude a star would have if it were placed at a standard distance of 10 parsecs (32.6 light-years) from the observer.

- Temperature: Represented by the symbol "T". It refers to the surface temperature of a star, typically measured in Kelvin.

- Mass: Represented by the symbol "M". It is the amount of matter contained in a star, typically measured in solar masses (M☉).
