What is the difference between a theory and a conclusion? How is a scientific theory different from a conclusion? A conclusion is based on observations and experiments completed within a limited time frame. A scientific theory is based on observations and experiments completed over an extended time frame. What is conclusion and recommendation? The interpretations […]
What is mass in grams of one n2 molecule?
Why are magnetic patterns important?
Why are magnetic patterns important? Magnetic patterns are important evidence for plate tectonics because we can use the magnetic signatures of rock to identify the movement of large… What changes cause magnetic striping? The striped magnetic pattern develops because, as oceanic crust pulls apart, magma rises to the surface at mid-ocean ridges and spills out […]
Does higher frequency mean more power?
Does higher frequency mean more power? Higher frequency does not mean more power. Usually it is more difficult to get high power from a higher frequency laser. There is no magic photon pump that you can just tune to higher frequency and get the same number of photons per second and hence higher power. Is […]
What soil takes the longest to form?
What soil takes the longest to form? The time needed to form a soil depends on the latitude: in environments characterized by a mild climate, it takes 200-400 years to form 1 cm of soil. in wet tropical areas soil formation is faster, as it takes 200 years. in order to accumulate enough substances to […]
What are the five steps of the SQ3R method?
What are the five steps of the SQ3R method? SQ3R is a reading comprehension method named for its five steps: survey, question, read, recite, and review. Follow the steps below to learn how to glean as much information as possible from the text requirements from any class. Remember: The information you gain from reading is […]
What is shear strain?
What is shear strain? Shear strain is the ratio of the change in deformation to its original length perpendicular to the axes of the member due to shear stress. Shear stress is stress in parallel to the cross section of the structural member. Is the measure of the rigidity of the body given by the […]
Is it OK to wear a knee brace all day?
What happens when SiO2 is treated with HF?
What happens when SiO2 is treated with HF? When silicon dioxide (SiO2) is heated with hydrogen fluoride (HF), it forms silicon tetrafluoride (SiF4). The SiF4 formed in this reaction can further react with HF to form Hydrofluorosilicic acid. What reacts with HF? When human tissue is exposed to concentrated HF, the molecules disassociate into individual […]
How far away can you feel a 9.0 earthquake?
How far away can you feel a 9.0 earthquake? 565 miles Do humans cause earthquakes? Induced seismicity refers to typically minor earthquakes and tremors that are caused by human activity that alters the stresses and strains on the Earth’s crust. Can you feel a 1.0 earthquake? A small earthquake far away will probably not be […]
