What is the net external force on an object in free fall? The net external force is just the weight of the object (F = W). Substituting into the second law equation gives: a = W / m = m * g / m = g . The acceleration (change of velocity) of the object […]
Is water a molecule or compound?
Is water a molecule or compound? Water is a compound. It contains more than one element: hydrogen and oxygen atoms are joined together; as illustrated in the video clip Elements and Compounds, above. An important feature of compounds is that they are very different from the elements from which they are made. Which is not […]

Step 2: Call for help. Step 3: Check for a response. Step 4: Check the casualty’s airway. Step 5: Check the casualty is […]
What is Gauss law for electric flux?
What is Gauss law for electric flux? Gauss’s law states that: The net outward normal electric flux through any closed surface is proportional to the total electric charge enclosed within that closed surface. How do you fix electric flux problems? Solution: To compute electric flux, we need the magnitude of the electric field, area of […]
What is difference between hypothesis and prediction?
What is difference between hypothesis and prediction? Difference Between a Hypothesis and Prediction Hypothesis and prediction are both a type of guess. However, the hypothesis is an educated, testable guess in science. A prediction uses observable phenomena to make a future projection. What is the relationship between Type 1 and Type 2 error? In statistical […]
What happens if the body does not maintain homeostasis?
What happens if the body does not maintain homeostasis? When the cells in your body do not work correctly, homeostatic balance is disrupted. Homeostatic imbalance may lead to a state of disease. Disease and cellular malfunction can be caused in two basic ways: by deficiency (cells not getting all they need) or toxicity (cells being […]

How liquid is measured?
Which is an example of liquid glass thermometer?
Which is an example of liquid glass thermometer? Mercury Thermometers This type of thermometer was developed by a German based physicist named Daniel Gabriel Fahrenheit. It consists of mercury as a liquid filled in a glass tube. On the body of the glass tube, calibrated marks are provided which facilitates the reading of temperature. How […]
Which two organisms are the most closely related?
Which two organisms are the most closely related? Which pair of organisms are most closely related? Organisms 2 and 3 are most closely related because they have the same family name. Organism 2 is a lion, organism 3 is a common housecat, and organism 1 is a human. Which best describes the two types of […]
