The pressure is measured in ___. A. pascals B. pascal C. newtons D. newton 相关知识点: 试题来源: 解析 A。压强的单位是帕斯卡,“pascal”的复数形式“pascals”。选项 B“pascal”是单数形式,一般用于表达“一个帕斯卡”时,这里要用复数形式;选项 C“newtons”是“牛顿”,用于测量力;选项 D“newton...
Pressure is a term that can be defined in a number of ways. Chemistry and physics have different definitions for pressure which imply a similar meaning but different contexts are used. It is one of the fundamental properties associated with the substances which is measured in atm, pascals, torr...
- Since pressure is typically measured in Pascals (N/m²), we need to convert the volume from milliliters to cubic meters. - 20 ml = 20×10−3 L = 20×10−6 m³ = 20×10−3 L = 20×10−6 m³ 3. Substitute Values into the Kinetic Energy Formula: - Rearranging the...
Earth's atmosphere exerts a force of 124,500 N on a kitchen table with an area of 1.5 m{eq}^2 {/eq}. What is the pressure in pascals? Pressure The relationship between the force and the area where it is applied is called pressure...
pressure measurement, the use of PSI is relative to atmosphere. This is because PSI as measured by a PSI gauge is inherently measured as a differential balance against atmospheric pressure, generally being immersed in it. PSI measurement can also be absolute: relative to a vacuum or PSI ...
The next section explains how numbers (like the pressure values) are converted to decibels. 2. Formulation The decibel is a logarithmic ratio between two numbers – a measured value and areferencevalue. It is shown in two forms below:Equation 1for POWER quantities , andEquation 2for field AMP...
fluid can be measured. The deeper the object is placed in the fluid, the more pressure it experiences. This is because the weight of the fluid is above it. The more dense the fluid above it, the more pressure is exerted on the object that is submerged, due to the weight of the ...
The atmospheric pressure at sea-level is equivalent to the pressure exerted by ___ cm mercury column at that place. View Solution In one observation, the column in a mercury barometer (as is shown in Fig. ) has a measured height h of 740.35 mm. The temperature is −5.0∘ C, at w...
force per unit area,pressure,pressure level- the force applied to a unit area of surface; measured in pascals (SI unit) or in dynes (cgs unit); "the compressed gas exerts an increased pressure" vital sign- sign of life; usually an indicator of a person's general physical condition; "he...
force per unit area, pressure, pressure level - the force applied to a unit area of surface; measured in pascals (SI unit) or in dynes (cgs unit); "the compressed gas exerts an increased pressure" 7. head - the top of something; "the head of the stairs"; "the head of the page"...
