What is an anemometer explain with diagram? Anemometer is the device that is used to measure wind speed. Since wind speed plays an important role in the formation of storms, an anemometer becomes useful to predict the cyclones or storms in cyclone-prone areas. The anemometer measures in feet per minute, or FPM. Anemometer. What is […]

What is the minimum time that a warm up? How long should a warmup be? Try to spend at least 5 to 10 minutes warming up. The more intense your workout is going to be, the longer your warmup should be. Focus first on large muscle groups and then perform warmups that mimic some of […]

What are two ways to increase the resistance in a wire? length – longer wires have greater resistance. thickness – smaller diameter wires have greater resistance. temperature – heating a wire increases its resistance. What are three ways to decrease resistance in a wire? Changing the material, increasing the cross section area, lowering the temperature, […]

How do you calculate shear stress in a shaft? Shear Stress in Shafts Shear Stress in a Solid Shaft Equation. When torque or twisitn loading is applied to a cylindrical shaft, a shearing stress is applied to the shaft. The shear stress in a solid cylindrical shaft at a given location: σ = T r […]

Explanation: pure substances include elements and compounds. They have same boiling and melting point. What are the types of pure substance? The two main types of pure substances […]

What causes the pail to move in circular motion? As a bucket of water is tied to a string and spun in a circle, the tension force acting upon the bucket provides the centripetal force required for circular motion. As the moon orbits the Earth, the force of gravity acting upon the moon provides the […]

What does the reading on a voltmeter mean? A voltmeter measures how much voltage is passing between two points. It does this by measuring the difference between the positive input of voltage and the negative input of voltage. Display, where you’ll see the results of the measurement. If your meter is analog you’ll have to […]

What happens to the current in a circuit if a 1.5 volt battery? What happens to the current in a circuit if a 1.5- volt battery is removed and replaced by a 9-volt battery? The current would increase. 10. The relationship between resistance and current in a circuit is that the greater the resistance the […]
