Explanation:
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.

if we model the vibrating system as a mass on a spring, what is the mass necessary to achieve the desired resonant frequency when the tip is not interacting with the surface?
Answer:
2.5 micrograms
Explanation:
The frequency of a vibrating body reduces with increasing mass, but increases with increasing tension.
What is the relation of resonant frequency with mass?For a spring-mass system, the relationship between frequency and mass can be expressed as follows: as mass increases, frequency decreases; as mass decreases, frequency increases.
The frequency in this case is f, and the mass is m. The relationship between mass and frequency is therefore inverse.
Precession frequency drops when mass is doubled, since angular momentum also doubles at this point. As the radius grows, the angular momentum increases and the precession frequency decreases.
Mass and stiffness are two well-known factors that affect an object's resonance frequency.
While stiffness limits low-frequency transmission because less elastic, or stiff, materials vibrate at higher frequencies, mass limits high-frequency transmission because larger objects vibrate at lower frequencies.
Therefore, The resonant frequency should rise as mass decreases.

Explanation:
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.

Explanation:
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.

Concrete has a higher specific heat than does soil. Use this fact to explain (partially) why a city has a higher average temperature than the surrounding countryside.
Answer:
Since concrete has higher specific heat, it will absorb more heat and the temperatures will rise in proportion. The large amount of energy stored in concrete during the day as the sun falls on it is released at night, resulting in an higher average evening temperature than the countryside. The cool air in the surrounding countryside exerts a buoyant force on the warmer air in the city, pushing it upward and moving into the city in the process. Thus, evening breezes tend to blow from country to city.
Explanation:
The city has a higher average temperature than the surrounding countryside as most of the cities are made up of concrete designs one of the things which absorb a lot of heat.
What is soil?Soil contains lots of minerals as well as microorganisms. One can grow crops or vegetation on the soil. This is made up of various types of sand and granules that can be present.
Concrete absorbs more heat because of its high surface heat, which causes temperatures to rise proportionately. Asphalt absorbs a lot of energy generated by the sun each day and releases it at night, giving cities a warmer average nighttime weather than rural.
The heated air in the city is propelled higher and toward the city by the density of water of the cooler in the nearby countryside. As a result, evening gusts frequently travel between rural to city.
