Context: Earth formed at the same time as the other planets. The history of Earth is part of the history of the Solar System. Earth came together (accreted) from the cloud of dust and gas known as the solar nebula nearly 4.6 billion years ago, the same time the Sun and the rest of the solar system formed. Gravity caused small bodies of rock and metal orbiting the proto-Sun to smash together to create larger bodies. Over time, the planetoids got larger and larger until they became planets. When Earth first came together it was really hot, hot enough to melt the metal elements that it contained. Earth was so hot for three reasons: Gravitational contraction: As small bodies of rock and metal accreted, the planet grew larger and more massive. Gravity within such an enormous body squeezes the material in its interior so hard that the pressure swells. As Earths internal pressure grew, its temperature also rose. Radioactive decay: Radioactive decay releases heat, and early in the planets history there were many ra- dioactive elements with short half lives. These elements long ago decayed into stable materials, but they were responsible for the release of enormous amounts of heat in the beginning. Bombardment: Ancient impact craters found on the Moon and inner planets indicate that asteroid impacts were common in the early solar system. Earth was struck so much in its first 500 million years that the heat was intense. Very few large objects have struck the planet in the past many hundreds of millions of year. When Earth was entirely molten, gravity drew denser elements to the center and lighter elements rose to the surface. The separation of Earth into layers based on density is known as differentiation. The densest material moved to the center to create the planets dense metallic core. Materials that are intermediate in density became part of the mantle (Figure 1.1). Lighter materials accumulated at the surface of the mantle to become the earliest crust. The first crust was probably basaltic, like the oceanic crust is today. Intense heat from the early core drove rapid and vigorous mantle convection so that crust quickly recycled into the mantle. The recycling of basaltic crust was so effective that no remnants of it are found today. There is not much material to let us know about the earliest days of our planet Earth. What there is comes from three sources: (1) zircon crystals, the oldest materials found on Earth, which show that the age of the earliest crust formed at least 4.4 billion years ago; (2) meteorites that date from the beginning of the solar system, to nearly 4.6 billion years ago (Figure 1.2); and (3) lunar rocks, which represent the early days of the Earth-Moon system as far back as 4.5 billion years ago.
Question: which is not a reason why earth was molten in its early days?
the sun

Context: In a New York City courthouse, an eighteen-year-old boy from a slum is on trial for allegedly stabbing his father to death. Final closing arguments having been presented, a visibly bored judge instructs the jury to decide whether the boy is guilty of murder. If there is any reasonable doubt of his guilt they are to return a verdict of not guilty. The judge further informs them that a guilty verdict will be accompanied by a mandatory death sentence.The jury retires to a private room, where the jurors spend a short while getting acquainted before they begin deliberating. It is immediately apparent that the jurors have already decided that the boy is guilty, and that they plan to return their verdict without taking time for discussion with the sole exception of Juror 8 (Henry Fonda), who is the only "not guilty" vote in a preliminary tally. He explains that there is too much at stake for him to go along with the verdict without at least talking about it first. His vote annoys the other jurors, especially Juror 7 (Jack Warden), who has tickets to a baseball game that evening; and Juror 10 (Ed Begley Sr.), who believes that people from slum backgrounds are liars, wild, and dangerous.The rest of the film's focus is the jury's difficulty in reaching a unanimous verdict. While several of the jurors harbor personal prejudices, Juror 8 maintains that the evidence presented in the case is circumstantial, and that the boy deserves a fair deliberation. He calls into question the accuracy and reliability of the only two witnesses to the murder, the "rarity" of the murder weapon (a common switchblade, of which he has an identical copy), and the overall questionable circumstances. He further argues that he cannot in good conscience vote "guilty" when he feels there is reasonable doubt of the boy's guilt.Having argued several points and gotten no favorable response from the others, Juror 8 reluctantly agrees that he has only succeeded in hanging the jury. Instead, he requests another vote, this time by secret ballot. He proposes that he will abstain from voting, and if the other 11 jurors are still unanimous in a guilty vote, then he will acquiesce to their decision. The secret ballot is held, and a new "not guilty" vote appears. This earns intense criticism from Juror 3 (Lee J. Cobb), who blatantly accuses Juror 5 (Jack Klugman) who had grown up in a slum of switching out of sympathy toward slum children. However, Juror 9 (Joseph Sweeney) reveals that he himself changed his vote, feeling that Juror 8's points deserve further discussion.Juror 8 presents a convincing argument that one of the witnesses, an elderly man who claimed to have heard the boy yell "I'm going to kill you" shortly before the murder took place, could not have heard the voices as clearly as he had testified due to an elevated train passing by at the time; as well as stating that "I'm going to kill you," is often said by people who do not literally mean it. Juror 5 changes his vote to "not guilty". Soon afterward, Juror 11 (George Voskovec) questions whether it is reasonable to suppose the defendant would have fled the scene, having cleaned the knife of fingerprints but leaving it behind, and then come back three hours later to retrieve it (having been left in his father's chest). Juror 11 then changes his vote.Juror 8 then mentions the man's second claim: upon hearing the father's body hit the floor, he had run to the door of his apartment and seen the defendant running out of the building from his front door in 15 seconds. Jurors 5, 6 and 8 question whether this is true, as the witness in question had had a stroke, limiting his ability to walk. Upon the end of an experiment, the jury finds that the witness would not have made it to the door in enough time to actually see the killer running out. Juror 8 concludes that, judging from what he claims to have heard earlier, the witness must have
Question: In the secret ballot who is the first to support Juror 8?
juror 9

Context: Both you and the speck of dust consist of atoms of matter. So does the ground beneath your feet. In fact, everything you can see and touch is made of matter. The only things that arent matter are forms of energy, such as light and sound. Although forms of energy are not matter, the air and other substances they travel through are. So what is matter? Matter is defined as anything that has mass and volume. Mass is the amount of matter in a substance or object. Mass is commonly measured with a balance. A simple mechanical balance is shown in Figure 3.1. It allows an object to be matched with other objects of known mass. SI units for mass are the kilogram, but for smaller masses grams are often used instead. The more matter an object contains, generally the more it weighs. However, weight is not the same thing as mass. Weight is a measure of the force of gravity pulling on an object. It is measured with a scale, like the kitchen- scale in Figure 3.2. The scale detects how forcefully objects in the pan are being pulled downward by the force of gravity. The SI unit for weight is the newton (N). The common English unit is the pound (lb). With Earths gravity, a mass of 1 kg has a weight of 9.8 N (2.2 lb). Problem Solving Problem: At Earths gravity, what is the weight in newtons of an object with a mass of 10 kg? Solution: At Earths gravity, 1 kg has a weight of 9.8 N. Therefore, 10 kg has a weight of (10 9.8 N) = 98 N. You Try It! Problem: If you have a mass of 50 kg on Earth, what is your weight in newtons? An object with more mass is pulled by gravity with greater force, so mass and weight are closely related. However, the weight of an object can change if the force of gravity changes, even while the mass of the object remains constant. Look at the photo of astronaut Edwin E. Aldrin Jr taken by fellow astronaut Neil Armstrong, the first human to walk on the moon, in Figure 3.3. An astronaut weighed less on the moon than he did on Earth because the moons gravity is weaker than Earths. The astronauts mass, on the other hand, did not change. He still contained the same amount of matter on the moon as he did on Earth. The amount of space matter takes up is its volume. How the volume of matter is measured depends on its state. The volume of liquids is measured with measuring containers. In the kitchen, liquid volume is usually measured with measuring cups or spoons. In the lab, liquid volume is measured with containers such as graduated cylinders. Units in the metric system for liquid volume include liters (L) and milliliters (mL). The volume of gases depends on the volume of their container. Thats because gases expand to fill whatever space is available to them. For example, as you drink water from a bottle, air rushes in to take the place of the water. An "empty" liter bottle actually holds a liter of air. How could you find the volume of air in an "empty" room? The volume of regularly shaped solids can be calculated from their dimensions. For example, the volume of a rectangular solid is the product of its length, width, and height (l w h). For solids that have irregular shapes, the displacement method is used to measure volume. You can see how it works in Figure 3.4 and in the video below. The SI unit for solid volumes is cubic meters (m3 ). However, cubic centimeters (cm3 ) are often used for smaller volume measurements. Matter has many properties. Some are physical properties. Physical properties of matter are properties that can be measured or observed without matter changing to a different substance. For example, whether a given substance normally exists as a solid, liquid, or gas is a physical property. Consider water. It is a liquid at room temperature, but if it freezes and
