What relationship between the Sun and Earth did?
The Earth revolves (orbits) around the Sun in one year. The Earth's rotation axis is tilted relative to the plane of its orbit around the Sun. This tilt of the Earth is responsible for the seasons as the Earth orbits the Sun. The Sun provides energy that sustains all life on Earth.
What did Galileo discover in his legendary experiment on the Leaning Tower of Pisa group of answer choices?
What did Galileo discover in his legendary experiment on the Leaning Tower of Pisa? Galileo proved to objects with different masses fall at the same rate. This contradicted Aristotle's belief that objects fell in proportion to their mass.
What is the force on a cart that is pulled to the right with a 100 pounds of force and to the left with 30 pounds of force?
What is the net force on a cart that is pulled to the right with 100 pounds of force and to the left with 30 pounds of force? The net force is 70 pounds to the right.
When you stand at rest on a bathroom scale How does your weight compare with the support force from the scale?
When you stand at rest on a bathroom scale, how does your weight compare with the support force from the scale? Your weight is equal in magnitude and opposite in direction to the support force from the scale. A bowling ball at rest is in equilibrium.
What relationship between Earth and the Sun causes the seasons?
The earth's spin axis is tilted with respect to its orbital plane. This is what causes the seasons. When the earth's axis points towards the sun, it is summer for that hemisphere. When the earth's axis points away, winter can be expected.
Which of the following is true about the Earth’s relationship to the Sun quizlet?
Which of the following is true about the earth's relationship to the sun? The seasons are caused by the tilt of the earth on its axis as it revolves around the sun. A climax community reaches a peak phase of growth and then, as part of its cycle, dies.
What did Galileo discover when he dropped two cannon balls of different weights from the Leaning Tower of Pisa?
What did Galileo discover when he dropped two cannon balls of different weights from the Leaning Tower of Pisa? The time for both of the balls to reach the ground was the same. Which scientist first discovered that white light is a mixture of a rainbow spectrum of light rays? You just studied 12 terms!
What is the Leaning Tower of Pisa experiment by Galilei and what is the implication of this experiment?
According to the story, Galileo discovered through this experiment that the objects fell with the same acceleration, proving his prediction true, while at the same time disproving Aristotle's theory of gravity (which states that objects fall at speed proportional to their mass).
What kind of speed is registered by an automobile speedometer average speed or instantaneous speed?
The speedometer of a car reveals information about the instantaneous speed of your car. It shows your speed at a particular instant in time. On the average, your car was moving with a speed of 25 miles per hour.
Which varies with radial distance on a rotating turntable tangential speed or rotational speed?
On a rotating turntable, does tangential speed or rotational speed vary with distance from the center? Rotational speed does not vary with distance. Rotational speeds is the measurement of revolutions per unit of time. Tangential speed depends on radial distance.
When you stand on a floor does the floor exert an upward force against your feet How much force does it exert Why aren’t you moved upward by this force?
How much force does it exert? Why aren't you moved upward by this force? Yes, the upward force exerts the same amount of force that is pushing down on it-the same as my weight. I'm not moved upward because it is equal on both sides, net force is zero.
What is the net force on a bathroom scale when a person stands on it?
What is the net force on a bathroom scale when a 110-pound person stands on it? Answer: Zero–the scale is at rest. The scale reads the support force, not the net force.
How does the Earth Sun relationship Cause day and night?
The sun thus produces a daily solar arc, which is the apparent path of the sun"s motion across the sky. At different latitudes, the sun will travel across the sky at different angles each day. The rotation of the earth about its axis also causes the day and night phenomenon.
What is the relationship of seasons with the position of the Sun in the sky?
As Earth orbits our Sun, the position of its axis relative to the Sun changes. This results in a change in the observed height of our Sun above the horizon. For any given location on Earth, our Sun is observed to trace a higher path above the horizon in the summer, and a lower path in the winter.
Is Earth farther from the sun in the winter and closer in the summer explain?
It is all about the tilt of the Earth's axis. Many people believe that the temperature changes because the Earth is closer to the sun in summer and farther from the sun in winter. In fact, the Earth is farthest from the sun in July and is closest to the sun in January!
How much of the Earth’s energy comes from the sun?
100% of the energy entering earth's atmosphere comes from the sun. ~50% of the incoming energy is absorbed by the earth's surface i.e. the land and oceans.
What was Galileo’s thought experiment that led to his hypothesis that all objects fall at the same rate?
Galileo's idea for slowing down the motion was to have a ball roll down a ramp rather than to fall vertically. He argued that the speed gained in rolling down a ramp of given height didn't depend on the slope. His argument was based on an experiment with a pendulum and a nail, shown on page 171 of Two New Sciences.
How did Galileo prove that different bodies fall towards the Earth at the same rate?
He dropped spheres of different masses and materials simultaneously from the top. To a surprise of the gathering, all the spheres reached the earth's surface at the same time. So, he concluded that the acceleration of an object, falling freely towards the earth does not depend on the mass of the object.
Who dropped balls off the Leaning Tower of Pisa?
Galileo Galilei May 6, 2004: Four hundred years ago–or so the story goes–Galileo Galilei started dropping things off the Leaning Tower of Pisa: Cannon balls, musket balls, gold, silver and wood. He might have expected the heavier objects to fall faster.
What does a vertical line on a distance time graph indicate?
A vertical line on a distance-time graph indicates that an object is stationary. A horizontal line on a distance-time graph indicates that an object is stationary. Speed is calculated by multiplying the time of travel by the distance traveled. Speed is calculated by dividing distance by time.
How do you measure instantaneous speed class 9?
Instantaneous speed (v) = distance/ time For uniform motion, instantaneous speed is constant. In other words, we can say that instantaneous speed at any given time is the magnitude of instantaneous velocity at that time.
How does the tapered rim of a wheel on a railroad train rolling along a track allow one part of the rim to roll faster than another part?
How does the tapered rim of a wheel on a railroad train allow one part of the rim to have a greater tangential speed than another part when it is rolling on a track? The tangential speed is proportional to the radius. The inside of the wheel rolls on a larger radius than the outside of the wheel.
What is the angle formed between the vectors of centripetal acceleration and centripetal force?
What is the angle formed between the vectors of centripetal acceleration and centripetal force? The angle between the centripetal acceleration and the centripetal force is 00 degrees. Both physical quantities are directed toward the center of the circulating body.
How many significant forces act on a book at rest on a table identify the forces?
Two significant forces act on the book: the force due to gravity and the support force (normal force) of the table.
Can you use 2 scales to weigh yourself?
Yes but for one source of error. If you stand on a pair of scales, the force on each may have equal (but opposite) horizontal forces. This will likely mess up the reading for some designs of scale where the assumption was that the force would be vertical.
When a gymnast hangs from a pair of gym rings the upward support forces by the rings will always?
Two equal and opposite forces of 2.0 N act on an object. The net force on the object is _____. Hang from a pair of gym rings and the upward support Forces of the rings will always: add up and combine to equal your weight.
What is the relationship between Earth and the Sun on March 21 or 22?
The vernal or spring equinox occurs in the northern hemisphere on March 21 or 22 (the fall equinox of the southern hemisphere). September 22 or 23 marks the northern hemisphere autumnal or fall equinox. As Earth orbits our Sun, the position of its axis relative to the Sun changes.
Where is the Earth in relation to the Sun and moon?
The average distance from the Earth to the Moon is 384,403 km. And the average distance from the Earth to the Sun is 149,597,887 km. If you divide these two numbers, you get approximately 389. Now, if you divide the diameter of the Sun (1.4 million km) by the diameter of the Moon (3,474 km), you get 403.
How does the Earth sun relationship affect climate?
The Earth's climate system depends entirely on the Sun for its energy. Solar radiation warms the atmosphere and is fundamental to atmospheric composition, while the distribution of solar heating across the planet produces global wind patterns and contributes to the formation of clouds, storms, and rainfall.
Why is the distance between the Earth and the sun not always equal?
Distance Information. Distances in the solar system are commonly measured in Astronomical Units (AU). An AU is simply the average distance between the Earth and the Sun. Because the Earth's orbit around the Sun is an ellipse, the Earth is not always the same distance from the Sun.
