What is balancing a centrifuge and why is it important? Why Balancing Your Laboratory Centrifuge Matters Out of balance loading causes the moving parts to shake uncontrollably. At best, this means the motor and bearings wear out more quickly. At worst, it risks sudden and explosive failure of the motor or rotor, and serious injury […]

What are the 3 ways machines make work easier?
What are the 3 ways machines make work easier? Background Information. There are three ways simple machines make work easier: by increasing the distance through which force is applied, by changing the direction of applied force, or by multiplying force of speed of the energy applied. Why is no machine 100 efficient? A machine cannot […]
What are three ways to show how energy flows through an ecosystem?
What are three ways to show how energy flows through an ecosystem? Key Points Food webs illustrate how energy flows through ecosystems, including how efficiently organisms acquire and use it. Autotrophs, producers in food webs, can be photosynthetic or chemosynthetic. Photoautotrophs use light energy to synthesize their own food, while chemoautotrophs use inorganic molecules. Why […]
What is the difference between slip rings and split rings?
What is the difference between slip rings and split rings? What is the difference between a split-ring and a slip-ring commutator? A split-ring makes the current change direction every half-rotation, whereas a slip-ring commutator merely maintains a connection between the moving rotor and the stationary stator. Which device uses slip rings? Slip rings are used […]
Does gravitational force increase weight?
Does gravitational force increase weight? That is, the weight of an object is determined by the pull of gravity on it. Thus, an object’s physical weight may change from place to place: if a body weighs 54 kg on Earth, its weight will be just over 9 kg on the Moon, since the Earth’s gravitational […]

Graphene supercapacitors. Redox flow batteries. Aluminum-graphite batteries. Bioelectrochemical batteries. Solar panels. Powered roads. What should I do with dead batteries? Ordinary Batteries: […]
How do you fix a dead zone?
How do you fix a dead zone? Managing Runoff to Reduce the Dead Zone Nutrient management: The application of fertilizers can vary in amount, timing, and method with varying impacts on water quality.
