Which statement best describes the relationship between work and energy? Which statement best defines the relationship between work and energy? Work can transfer energy between objects and cause a change in the form of energy. Gabriel is performing an experiment in which he is measuring the energy and work being done by a ball rolling […]
How do you calculate input impedance of an amplifier?
How do you calculate input impedance of an amplifier? The generalised formula for the input impedance of any circuit is ZIN = VIN/IIN. The DC bias circuit sets the DC operating “Q” point of the transistor and as the input capacitor, C1 acts as an open circuit and blocks any DC voltage, at DC (0Hz) […]
Who is responsible for using a fire extinguisher at work?
Who is responsible for using a fire extinguisher at work? Every employer, owner or occupier of a business premises is accountable for fire safety and fire protection. To comply with fire safety legislation, it is a legal requirement to have an ‘appropriate person’ who is trained to carry out fire safety measures. What does OSHA […]
What is the difference between pseudoscience and science?
What is the difference between pseudoscience and science? While a pseudo-science is set up to look for evidence that supports its claims, Popper says, a science is set up to challenge its claims and look for evidence that might prove it false. In other words, pseudo-science seeks confirmations and science seeks falsifications. What is scientific […]
What is the importance of power supply?
What is the importance of power supply? A power supply is an electrical device that supplies electric power to an electrical load. The primary function of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load. How important is power supply for PC? […]

Moisture Content. Flowability. Grain Size. Grain Shape. Collapsibility. Refractory Strength. What kind of sand is used in sand casting? Silica sand What are the materials used […]
How do you calculate bevel gear ratio?
Why does my car have no power steering?
Why does my car have no power steering? Improper Fluid Levels Too much and your valves and seals could collapse under the pressure. Not enough and the fluid can’t exert the force needed to turn your car. Replacing your fluid on time will help prevent this issue, but any leaks can cause a loss of […]
What is the clapeyron equation used for?
What is the clapeyron equation used for? The Clapeyron equation helps us determine thermodynamic values for reactions or phases. When combined with volume data, we can use the slope of an experimentally-determined reaction to calculate the Δ S of the reaction, and to calculate the entropy of formation (ΔSf) of a particular phase. What can […]
Which of the following welding processes does not involve melting of the parts to be joined?
Which of the following welding processes does not involve melting of the parts to be joined? Like the first welding process, forge welding, some modern welding methods do not involve the melting of the materials being joined. One of the most popular, ultrasonic welding, is used to connect thin sheets or wires made of metal […]
