Do zombies feel pain? Zombies do not feel pain, nor do they respond to threats or demonstrations to incite fear and crowd dispersion. They just simply want to consume and spread and should be feared by the human race. Do zombies sleep? Zombies are on the prowl at all times of day and night! They […]

Is F2 a single or double bond? On the right is the F2 molecule. The diatomic fluorine molecule (F2) contains a single shared pair of electrons. Each F atom also has three pair of electrons that are not shared with the other atom. Is h2 a single or double bond? Hydrogen forms 1 single bond […]

What if the magnification is less than 1? A magnification of 1 (plus or minus) means that the image is the same size as the object. If m has a magnitude greater than 1 the image is larger than the object, and an m with a magnitude less than 1 means the image is smaller […]

How many miles per gallon does a freight train get? 492 miles How much it costs to run a train? By way of comparison, an electric train which consumes 30 kWh per train-mile at 12¢ per kWh would have a fuel cost of only $3.60 per train-mile and many trains average less. With the proviso […]

How do you calculate cfm of air flow? To calculate Air Flow in Cubic Feet per Minute (CFM), determine the Flow Velocity in feet per minute, then multiply this figure by the Duct Cross Sectional Area. What are the different methods used for measuring air flow? The most common and easiest way to measure or […]

How many neutrons does 19 9 F? 10 neutrons Is fluorine-19 an ion? According to the periodic tale, fluorine, F, has an atomic number of 19. We can conclude that fluorine gained an electron to reach a stable octet configuration, and because it has an extra electron it is now called a fluorine ion. Why […]

What happens if a runner misses a base on a home run? A runner who misses the plate after overrunning or oversliding it may return to touch it (NFHS 8-2 Nt.; NCAA 8-6a4; pro 5.09b12). If the runner immediately makes an effort to touch the plate, he is out only when he is tagged. When […]

Which type of contraction builds muscle faster? Combining eccentric and concentric muscle contractions produces greater results in strength training, as it increases muscle strength and mass. How many types of muscle contractions are there? three types What is responsible for causing muscle contractions? 1. A Muscle Contraction Is Triggered When an Action Potential Travels Along […]

How fast can a freight train accelerate? The final factor and one frequently overlooked is the tractive effort required for acceleration of the train. It takes about 10 pounds per ton to accelerate to a speed of 6 miles per hour in one minute or 12 miles per hour in two minutes, a reasonable rate […]

Do air bubbles get bigger? The bubble gets bigger when it go up to the surface because there is less pressure as it rises to the surface. Air is less dense than water and thus the force of gravity is less on the bubble than on the surrounding water then the bubbles rise. What happens […]
