Explain how spring and neap tides are created. Tides are created by the gravitational pull of the sun and moon. When the sun and moon align their gravitational pulls combine creating the highest high tides and the lowest low tides, also known as the spring tides. When the sun and moon are at 90° angles from one another their gravitational pulls are pulling in different directions, therefore the tides are minimized, also known as neap tides. b.
Method: We first measured for x, R’, and R_sun–for both the initial and final positions of the sunspot. Since both the Earth and the sun orbit, our perspective that we observe the sunspots change. Because the sun and Earth are both spheres on a tilted rotational axis (we must keep in mind that this is from the horizontal and ‘bird’s eye-view’ of the sun), we solved for the longitudinal angles of both the initial and final sun spot positions using the following formulas: θ=sin〖x/(R ')〗 〖θ=sin〗〖x/R_sun 〗 To find ω_S, we must correct for Earth’s orbit because the sun moves at a faster rate than the Earth. To do so, we find ω_E, which is 2.0 x 〖10〗^(-7)rad/s, and ∆ω_OS, using the equation ∆ω_OS=∆θ/∆t . We can substitute the angular velocities of the Earth and the observed angle into the equation ω_S=ω_E+Δω_OS, to find the true angular velocity of the sun.
As the planet’s core began to cool its surface deformed. Resultantly, compression folds and rough plains are present on Mercury’s surface. As colonization on other planets has been a hot topic in the past. So, different space shuttles were sent to study atmospheric conditions of the planets in our solar system. By that means, mercury is suggested to be a possible target for space colonization.
It’s an astrological age, which occurs because of a real motion of Earth known as the precession of the equinoxes, which, for example, causes the identity of the pole star to change over time. The cycle of precession lasts 25,800 years, and there are 12 constellations of the Zodiac. So, roughly every 2,150 years, the sun’s position at the time of the
To begin with, the size of a planet determines the amount of dimming during a transit. Larger planets block more of the star, and therefore the dip in brightness is larger. Knowing the size of Trappist 1, the astronomers could measure the transit dimming due to each planet to determine its size. (According to the Planetary society Transit dimming is a method for Finding Earth 's. This method detects distant planets by measuring the minute dimming of a star as an orbiting planet passes between it and the Earth.
Kepler’s third law modified by Newton is T^2(Me+Mm)= D^3. T is the orbital period in years and D is the distance between the Earth and Moon in AU. Me is the Mass of the Earth and Mm is the mass of the moon. Then I set Me+Mm=Mt. Mt is the total mass of the Earth and Moon combined.
To make a declaration about the earth’s shape, the shadow cast must be appreciated from multiple light source angles, not assumed to be at a 90 degree angle to a flat object. In addition, Aristotle would argue that one must observe the stages of a total lunar eclipse, as the moon travels completely into and then out of earth’s shadow, displaying a circular shadow at all times. Referring back to the light example, if the light is always shining directly in front of the round object, for instance a pie tin, a similar circular shadow will be formed on the wall. But, if the light source is moved off to the side, a more oblong shadow is formed, with portions of the shadow almost linear. So, in this case, only a sphere would maintain the circular shadow shape, because the sphere’s profile is circular on all sides.
The peak period from a wind speed of 7.5 m/s is calculated by multiplying the wind speed by 0.7500696 (7.5 x 0.7500696) which equals a peak period of 5.63 seconds. Wave group speed can be estimated by multiplying this value by 0.78 (5.63 x 0.78) which equals a wave group speed of 4.39 m/s. The time it takes for the swell to arrive to the surf break can be calculated by taking the distances between the surf break and the center of the storm and dividing it by wave group speed (144243m / 4.39m/s) which equals 328,529.25 seconds or 91.25 hours or 3.8 days. Significant wave height as the waves move away from the storm can be calculated by squaring the value of the wind speed and dividing it by the gravity constant then multiplying the products by 0.22 ([7.52 / 9.8] x 0.22) which equals 1.26 m or 4.13
“The early solar system was a violent place, and a number of bodies were created … one of these bodies [Theia] crashed into Earth not long after the planet was created.” (Redd, Paragraph 2). According to Newton’s third law, for every action there is an equal and opposite reaction, the action of Theia crashing into Earth had a reaction of throwing vaporized parts of Earth into space. Then, with the help of gravity these particles fused together to create the moon. The Moon having particles from Earth helps to explains why isotopic compositions of oxygen and titanium are present on the Moon ,and therefore Earth, but very sparse in every other rocky body in our solar system. All of this information is why The Giant Impactor Theory is the most accepted theory, in the science community, of how the moon came to
“Different constellations come into view as the Earth rotates on its axis and makes its yearly revolution around the Sun, the sphere appears to shift.” (Astronomy and Space). Constellations can be categorized as Greek constellations, or zodiacs. These, as well as all constellations, were utilized in different ways to fit peoples ' needs, whether past or present. Many constellations such as Leo (the zodiac lion), or Orion (the mythical Greek hunter) have been created and documented for many years. Every constellation is thought to have a creation story behind it which explains how it came to be.
