Carbon-14 is constantly being produced in the upper atmosphere, and the amount is in
equilibrium. As long as an organism is alive, it keeps its carbon isotopes in balance with the
atmosphere, but at soon as it dies, it stops taking up new 14C, and so the geologic clock starts.
You found a shell buried in sedimentary layers, which has 6% of its original 14C left.
Determine the age of the shell. Show your work.

PLEASE ANSWER IN C# and explain each step so I can understand please (: The last experts did not answer in C# (reject my question if you can't). The controversial issue of global warming has been widelypublicized by the film “An Inconvenient Truth,” featuring former Vice President Al Gore. Mr. Goreand a U.N. network of scientists, the Intergovernmental Panel on Climate Change, shared the 2007Nobel Peace Prize in recognition of “their efforts to build up and disseminate greater knowledgeabout man-made climate change.” Research both sides of the global warming issue online (you might want to search for phrases like “global warming skeptics”). Create a five-question multiplechoicequiz on global warming, each question having four possible answers (numbered 1–4). Be objectiveand try to fairly represent both sides of the issue.

A example of one is attached as well. The problem about the ROCK is the example CR. The problem you ARE writing a CR for is 5x^2-8x=3. Instructions below. For the CR's, claim you should answer the question of , do you get 2 real solutions, 1 real solution, or 2 complex solutions? For your reasoning you should explain how you know. Use the example attached to help you answer. hints: that plus minus sign means there are two answers. If the number under the square root is positive, you have two real solutions. If the number is negative you have two complex solutions. If the number is 0 under the square root you have 1 real number solution.arrow_forward
- Impact Energy. Consider a comet about 2 kilometers across with a mass of 4 × 1012 kg. Assume that it crashes into Earth at a speed of 30,000 meters per second (about 67,000 miles per hour). a. What is the total energy of the impact, in joules? (Hint: The kinetic energy formula tells us that the impact energy in joules will be 1 × m × v2, where 2 m is the comet’s mass in kilograms and v is its speed in meters per second.) b. A 1-megaton nuclear explosion releases about 4 × 1015 joules of energy. How many such nuclear bombs would it take to release as much energy as the comet impact? c. Based on your answers, comment on the degree of devastation the comet might cause.arrow_forwardWe need to create a scale model of the solar system (by shrinking the sun down to the size of a basketball or ~30cm). First, we will need to scale down actual solar system dimensions (planet diameters and average orbital radiuses) by converting our units. There are two blank spaces in the table below. We will effectively fill in the missing data in the next set of questions. Use the example below to help you. Example: What is the scaled diameter of Mercury if the Sun is scaled to the size of a basketball (30 cm)? The actual diameter of Mercury is 4879 km The Sun's diameter is 1392000 km If the Sun is to be reduced to the size of a basketball, then the conversion we need for this equation will be: 30cm1392000km Here is how we run the conversion: 4879km×30cm1392000km=0.105cm or 0.11cm if we were to round our answer. This means that if the sun in our model is the size of a basketball, Mercury is the size of a grain of sand. We can also see by looking at the table, that we would…arrow_forwardPleade help me with my hw. Tysm❤️ Explain all answers in 5-6 sentences for number 1. ACTIVITY: Answer the following accordingly.

You want to make sure that the Perseverance rover gets built and sent to Mars, just like your "memory of the future", i.e. your memory of the summer of 2020. In the space provided below, write a description, in your own words, of why the Perseverance rover has the potential to do great science. Here are the things to focus on: What are the two or three most special things about Perseverance, when it comes to the search for possible ancient life on Mars? In particular, you want to make sure to describe and explain the one particular thing that Perseverance will hopefully do, which will start the long process of giving scientists the opportunity to learn about Mars in a way they never could do before.arrow_forwardGive a Claim and Evidence to each question.5.
