State three means of operating a power tool
Answer:
A power tool is a tool that is actuated by an additional power source and mechanism other than the solely manual labor used with hand tools. The most common types of power tools use electric motors. Internal combustion engines and compressed air are also commonly used. Other power sources include steam engines, direct burning of fuels and propellants, such as in powder-actuated tools, or even natural power sources such as wind or moving water. Tools directly driven by animal power are not generally considered power tools.
Power tools are used in industry, in construction, in the garden, for housework tasks such as cooking, cleaning, and around the house for purposes of driving (fasteners), drilling, cutting, shaping, sanding, grinding, routing, polishing, painting, heating and more.
Power tools are classified as either stationary or portable, where portable means hand-held. Portable power tools have obvious advantages in mobility. Stationary power tools, however, often have advantages in speed and precision. A typical table saw, for instance, not only cuts faster than a regular hand saw, but the cuts are smoother, straighter, and more square than what is normally achievable with a hand-held power saw. Some stationary power tools can produce objects that cannot be made in any other way. Lathes, for example, produce truly round objects.
Stationary power tools for metalworking are usually called machine tools. The term machine tool is not usually applied to stationary power tools for woodworking, although such usage is occasionally heard, and in some cases, such as drill presses and bench grinders, exactly the same tool is used for both woodworking and metalworking.
Explanation:
The form of energy delivered to an electrical generating turbine in a geothermal facility is in the form of ________.
Geothermal energy is a product of the heat of Earth's molten interior. The form of energy delivered to an electrical generating turbine in a geothermal facility is in the form of hot water or steam.
Geothermal energy is gotten so as to generate electricity. This is done when water is injected deep underground and it then comes back as steam or hot water.This is then converted to steam so as to drive a turbine on an electric power generator. The plants makes use of steam to produce electricity.
There are three main types of energy for electricity generation. They are fossil fuels which is made up of coal, natural gas, and petroleum, and then nuclear energy, and renewable energy sources.

an automobile radiator is filled to the brim with water when the engine is cool. what happens to the water when the engine is running and the water has been raised to a high temperature?
Answer:
(a) As the water rises in temperature, it expands or rises in pressure or both. The excess volume would spill out of the cooling system, or else the pressure would rise very high indeed.
(b) Modern cooling systems have an overflow reservoir to accept the excess volume when the coolant heats up and expands.
Explanation:
hope it helps!
Water expands more when the temperature is elevated, increasing its volume. Consequently, the steel radiator will leak water. When the engine is running, the water is heated to higher temperatures, which causes it to expand and spill out.
What engine is running, the water raised to a temperature?Your engine should operate between 195 and 220 degrees, according to the majority of experts. Your needle should always remain centered in your gauge in ideal circumstances.
A thermostat, cylinder sleeve, cooling water pump, and heat exchanger are all components of an engine cooling water system. Water System for Engine Cooling. The cooling water must be circulated throughout the engine by a cooling water pump.
Therefore, This is due to the fact that radiator water will freeze when temperatures in colder countries fall below zero degrees, which is the freezing point of water.

Cooling water available at 10°C is used to condense steam at 30°C in the condenser of a power plant at a rate of 0.60 kg/s by circulating the cooling water through a bank of 7-m-long 1.2-cm-internal-diameter thin copper tubes. Water enters the tubes at a mean velocity of 4 m/s and leaves at a temperature of 24°C. The tubes are nearly isothermal at 30°C. Determine the average heat transfer coefficient between the water, the tubes, and the number of tubes needed to achieve the indicated heat transfer rate in the condenser.

what factors need to be considered when building housing on a waterway
Answer:
Flooding
Explanation:
.
When building housing on a waterway one must always consider the factor of Flooding and its repercussions.
What is a Flood?A flood occurs when there is an excessive amount of water and it covers normally dry areas. The word can also refer to the tide's influx when used in the sense of "flowing water." Floods are a topic of research in the hydrology field and are very important to the fields of agriculture, civil engineering, and public health.
Floods have serious societal repercussions for both communities and people. As most people are well aware, flooding has a number of direct effects, including the loss of life, destruction of property, loss of crops and livestock, and worsening of health due to waterborne infections.
Stream gauges that are put in bodies of water close to inhabited areas are used to measure floods. The National Weather Service receives all data collected by them before it is sent to the United States Geological Survey (USGS), which erected and operates them (NWS)
