Answer the following question regarding field of view measurements. Enter your answer as a whole number (decimal format).
Imagine you are using a microscope where the diameter of the field of view at 4x is 10mm. You view the microbe below at 100x.
What is the size of each individual microbe? DO NOT ADD UNITS.
D1=4x and M1=5mm
In determining the least count of the main scale in the Vernier caliper, which of the following
method must be followed? *
O Divide the difference between two adjacent main scale values by the number of divisions between them.
O Divide the least count of the main scale by the number of division of the Vernier scale.
Multiply the least count of the Vernier scale by the number of Vernier division that is aligned with the main scale
mark.
O Read the main scale mark just before the zero mark of the Vernier scale.
Which of the following is least reasonable regarding the extinction of the dinosaurs?
Group of answer choices
Scientists originally believed that the Chicxulub crater was caused by a nuclear blast since the impact residue (e.g., melted bedrock, tektites, shocked quartz, etc.) discovered there was very similar to that found around nuclear test sites.
According to a well-established hypothesis, a meteor the size of a mountain slammed into Earth about 65 million years ago, filling the atmosphere with gas, dust, and debris that drastically altered the climate.
One key piece of evidence is a very high level of iridium in a layer of Earth, with lots of dinosaur fossils below but none above.
A huge impact crater linked to the impact event was found around coast of Mexico’s Yucatán Peninsula.
Although the impact occurred in the Gulf of Mexico, meteorite debris from the 'dinosaur rock' was discovered all over the world.

- 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.

- Read the following items carefully. State your assumptions if any. Show your COMPLETE solution and BOX your final answers. Keep your answers and solutions in 4 decimal places. > Initially, 100 milligrams of a new radioactive substance Tobium, named after its discoverer Sir Tobs, was discovered and collected from one of the moons of Jupiter. After 6 hours from collection, the mass decreased by 4%, If the rate of decay IS proportional to the amount of the substance present at time t, find the amount of Tobium remaining after 48 hours.arrow_forwardProblem 2. Planetary Body Composition: Density (Links to an external site.) of the Earth (Palen, et. al., 1st Edition, Chapter 6, problem 70) Earth’s mean (Links to an external site.) radius is 6,378 km and its mass is 5.97 x 1024 kg. CALCULATE Earth’s average (Links to an external site.) density. SHOW YOUR WORK. DO NOT LOOK UP THIS VALUE! The average density of Earth’s crust is 2,600 kg/m3. What does this tell you about Earth’s interior?arrow_forwardUpload a PDF document that shows your work and solution. The principle of radiometric dating is summarized with the following formula: N = No (4) where N is the current number of radioactive atoms in a sample, No is the initial number of radioactive atoms in a sample, ty is the length of time of one half-life of the radioactive element (measured in seconds), and t is the amount of time since the sample was formed (measured in seconds). This formula allows for the radiometric dating of rocks and other materials. Consider a rock that contains Uranium-238 that decays into Lead-206 with a half-life of 4.47 billion years. A rock is found that has 94.65% Uranium and 5.35% Lead - so, how old is this rock?arrow_forward
- I need to know the number of years! There is only one part to this question. The pictures show the "Figure" and "Bar charts" tabs and the "Graph" tab says this: A curve showing the percentage of radioactive atoms remaining in a mineral sample is graphed on a coordinate plane. The horizontal axis, labeled "Age in half-lives," ranges from 0 to 6. The vertical axis, labeled "Percentage remaining," ranges from 0 to 100. The curve enters the viewing field with a negative slope at (0, 100). The magnitude of the negative slope is progressively reduced such that it is nearly horizontal as it exits the viewing field at (6, 0.02).
