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 do I write a reflection? When writing a reflection paper on literature or another experience, the point is to include your thoughts and reactions to the reading or experience. You can present what you observed (objective discussion) and how what you experienced or saw made you feel and explain why (subjective discussion). How do […]

What is the weight of something in water? Weight of object in water = weight of object in vacuum – buoyant force. But Archimedes principle states that the buoyant force = weight of fluid displaced by object. From this volume you can get the mass of water displaced since the density of water is 977kg/m^3. […]

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 […]

Can coefficient of friction be greater than 1? The coefficient of friction depends on the objects that are causing friction. The value is usually between 0 and 1 but can be greater than 1. A value of 0 means there is no friction at all between the objects; such is possible with Superfluidity. A value […]

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 […]

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 […]

What happens if you pass electric current through a coiled conductor wire? Either an electric current is passed through the wire of the coil to generate a magnetic field, or conversely, an external time-varying magnetic field through the interior of the coil generates an EMF (voltage) in the conductor. The more turns of wire, the […]

What is the relationship between temperature and height in the thermosphere? The Thermosphere and Ionosphere The thermosphere lies above the mesopause, and is a region in which temperatures again increase with height. This temperature increase is caused by the absorption of energetic ultraviolet and X-Ray radiation from the sun. Is the thermosphere the hottest layer? […]
