What’s the the answer please

I Modified True or False. Analyze the following principles, concepts, or scenarios on vibration. Write the word True if the statement is correct otherwise, identify the word or phrase that made the statement false and replace it with the correct term on the blank provided before each item. Separate it with a comma. 8. The severity of sound is defined by the amplitude level. 9. Through spectral analysis, the signal is analyzed to determine any substantial reciprocal of one cycle motion coming from the machine's components. _10. In viscous damping, an inverse proportional relationship was observed between the velocity of the vibrating body and the damping force. _11. The Newton's second law of motion is applied to the mass or rigid body when dealing with principle of conservation of energy. _12. If no work is done on a conservative system by extermal forces other than gravity or other potential forces, then the total energy of the system varies. 13. In the case wherein the frequency…

The noise level in a factory with 12 identical machines running is 80 dB. At night, the factory must comply with local noise regulation not to exceed 75 dB. How many machines can be used at the night shift

QUESTION 2 SOALAN 2 a) The DP Transmitter device is used to measure level as an inferential measurement. When installing the DP Transmitter in an open tank at HP tapping point at 0%, the lower range values (LRV) and upper range values (URV) for the transmitter must be determined in order to properly register 0% at the LRV and 100% at the URV liquid level. By referring to Figure 2, calculate the calibrated range with specific gravity, SG is 1.1 and height, H of the tank is 100mm. Peranti Pemancar DP digunakan untuk mengukur paras sebagai ukuran taabir. Apabila memasang Pemancar DP di tangki yang terbuka di HP titik tirus pada 0%, nilai julat yang lebih rendah (LRV) dan nilai julat atas (URV) untuk pemancar mesti ditentukan untuk daftarkan betul pada 0% LRV dan 100% URV. Dengan merujuk Rajah 2, hitungkan julat yang dikalibrasi dengan graviti spesifik, S.G adalah 1.1 dan ketinggian, H tangki adalah 100mm. Tank open to Atmosphere Махт. Level Liquid DP Transmitter Vented to Atmosphere Min.…

Pressurized eyes Our eyes need a certain amount of internal pressure in order to work properly, with the normal range being between 10 and 20 mm of mercury. The pressure is determined by a balance between the fluid entering and leaving the eye. If the pressure is above the normal level, damage may occur to the optic nerve where it leaves the eye, leading to a loss of the visual field termed glaucoma. Measurement of the pressure within the eye can be done by several different noninvasive types of instruments, all of which measure the slight deformation of the eyeball when a force is put on it. Some methods use a physical probe that makes contact with the front of the eye, applies a known force, and measures the deformation. One non-contact method uses a calibrated “puff” of air that is blown against the eye. The stagnation pressure resulting from the air blowing against the eyeball causes a slight deformation, the magnitude of which is correlated with the pressure within the eyeball.…

A. A student establishes the time constant of a temperature sensor by first holding it immersed in hot water and then suddenly removing it and holding it immersed in cold water. Several other students perform the same test with similar sensors. Overall, their results are inconsistent, with estimated time constants differing by as much as a factor of 1.2. Offer suggestions about why this might happen. Hint: Try this yourself and think about control of test conditions. B. Which would you expect to be better suited to measure a time-dependent temperature, a thermal sensor (e.g., a thermocouple) having a small diameter spherical bead or one having a large diameter spherical bead? Why?

Handwritten solution required. Strictly don't use chatgpt. If you use chatgpt ,I will report the answer for sure. Mechanical engineering dynamics.
