The correct option is 10 to 100 Hz. A low pass and high pass filter are cascaded to create a band pass filter. It has two reactive elements, making it a second order filter.

The signal strength to frequency graph looks like this because this filter favors high frequencies: We may do a variety of signal processing operations using the low-pass and high-pass filters, including picking out a certain frequency band. We can easily sketch the perfect filter response since the -3dB point is also quite near to the place where the "unity gain" line and the asymptote for the filter's roll-off curve intersect.

Drawing piecewise-linear approximations for filter performance is no longer necessary in modern times thanks to the usage of computers, but this was not the case when electrical circuit design and analysis first started. Even with the introduction of electronic calculators, the majority of these activities were still done by hand.

The planet that is likely to have a large iron core if all three planets have similar rocky surfaces but different average densities is 6000 kg / m³

Density is directly proportional to he size of iron core. Larger the density of the planet larger will be the size of iron core of the planet. Smaller the density of the planet smaller will be the size of iron core of the planet.

Average density of a planet is the value of total mass divided by the total volume. If the average density of a planet is higher than 3000 kg / m³, the planet is terrestrial. If the average density of a planet is lesser than 2000 kg / m³, the planet is Jovian.

Divided by the amount of time passed, the average speed is obtained. The limit of average velocity as elapsed time approaches zero is the instantaneous velocity of an object. v (t) = d d t x (t). v (t) = d d t x (t).

The average velocity rate of change is a measure of how much one variable has changed overall relative to another. The instantaneous rate of change, also known as the derivative, quantifies the precise rate at which one variable changes in relation to a precise, extremely small change in another variable.Average speed is the ratio of an object's total distance travelled to its total travel time. Average acceleration is calculated by dividing the change in velocity by the amount of time that has passed; instantaneous acceleration is the acceleration at a specific time. Average acceleration is the acceleration at a specific moment in time; instantaneous acceleration is the velocity change divided by the amount of time that has passed.

To know the exact mass of a planet, we also need to be able to determine the angle at which the planet's orbit is tilted toward us.

To determine the mass of a planet, astronomers usually measure the small motions of the star caused by the gravitational pull of the orbiting planet. For a planet, figuring out the mass of the Earth is an extraordinary challenge with current technology.

Therefore, to measure the mass of a planet, measure the period and orbital radius of all satellites orbiting the planet, plot graph against R³/T² for all satellites, and calculate the mass of the planet. This is one way to do that.

According to Kepler's laws: If the orbital size (a) is expressed in astronomical units (1 AU is the average distance between the Earth and the Sun) and the period (P) is measured in years, Kepler's third law states that his P² = a³ increase. where P is the Earth year, a is the AU, and M is the mass of the central body in units of the mass of the Sun.

Answer:

The temperature of the early solar system explains why the inner planets are rocky and the outer ones are gaseous.

Explanation:

The outer planets are much larger than the inner planets. Because of their large mass and cooler temperature, they have a very different composition; they are mostly made of light elements with extended atmospheres in a gaseous form. Outer planets exist in much bigger systems than inner planets.

The reason for different composition of planets has to do with how the solar system formed. In the early solar system, there was a disk of material rotating around the Sun, from which the planets eventually formed. However, to form planets required some kind of initial clump in the protoplanetary disk. These clumps were probably formed from collisions of solid particles. Different elements become solid at different temperatures: the most common elements, hydrogen and helium, never became solid, but hydrogen compounds (like water) can solidify at colder temperatures, like those in the outer solar system. In the inner solar system, it was too hot for these compounds to solidify; only rocks and metals can solidify at these temperatures. Hence, only small planetesimals formed in the inner solar system.

This information could be used in the following ways: the braking distance of a skidding car will depend on its initial speed and the coefficient of kinetic friction.

Thus, if the coefficient of friction is known the initial speed can be determined from the length of the skid marks.

The radius in terms of x is 2/(π+4)

Area, a quantity that describes the extent of an area on a plane or curved surface. The area of ​​a planar region refers to the area of ​​a shape or planar layer, while surface area refers to the area of ​​an open surface or boundary of a three-dimensional object.

Given that,

y forms a circle of radius r

y = 2πr

r = y/2π

(2-y) forms Square Side x

(2-y) = 4x

x = (2-y)/4

Now Sum of Areas = Area of Square + Area of Circle

Sum = πr² + x²

Substitute the  values of r and x in above equation:

A(y) = y²/4π + (y-2)²/ 16

To maximize Area A(y)

A'(y) = 0

2y/4π + 2(y-2)/16 = 0

y/2π + (y-2)/8 =0

y = 2π/(π+4)

Following cooling, a white dwarf becomes too cold and dark to emit visible light.

Like our Sun, medium-mass stars generate helium by fusing hydrogen within their cores. Our Sun is now performing this. An outward pressure results from the heat the Sun produces during the nuclear fusion of hydrogen into helium. The Sun will run out of hydrogen in its core in about 5 billion years.

The Sun begins to collapse when it runs out of hydrogen to fuse, tipping the scales in favor of gravity. However, compacting a star makes it heat up once more, allowing it to fuse what little hydrogen is left in a shell surrounding its core.

The parallax angle for the star Hadar is 0.010 arcseconds. 100 PC far away is Hadar.

Parallax angle is a displacement or distinction in the apparent function of an item considered alongside two one-of-a-kind lines of sight and is measured by the attitude or semi-perspective of inclination among those two lines. because of foreshortening, close-by objects display a bigger parallax than farther items when found from distinct positions, so parallax may be used to determine distances.  

To a degree of big distances, including the gap between a planet or a star from Earth, astronomers use the precept of parallax. right here, the term parallax is the semi-perspective of inclination between sightlines to the megastar, as observed while Earth is on contrary sides of the solar in its orbit. those distances shape the lowest rung of what's called "the cosmic distance ladder", the first in a succession of methods by which astronomers determine the distances to celestial items, serving as a basis for other distance measurements in astronomy forming the higher rungs of the ladder.
