Solutions (Week-01) Chapter-01 1-12 A plastic tank is filled with water. The weight of the combined system is to be determined. Assumptions The density of water is constant throughout. Properties The density of water is given to be = 1000 kg/m3. Analysis The mass of the water in the tank and the total mass are mw =V =(1000 kg/m3)(0.2 m3) = 200 kg mtotal = mw + mtank = 200 + 3 = 203 kg Thus‚ 1-14 The variation of gravitational acceleration above the sea level is given as

tools for agriculture or hunting and even as artistic styles later on. There are 86 known metals so far that were discovered by time. From the first metal "Gold" discovered at 6000 BC‚ only 7 metals were known at antiquity "gold‚ copper‚ iron‚ lead‚ mercury‚ silver and tin". Later on metals were combined into alloys like bronze that is formed by a combination of copper and tin. Platinum and zinc are one of the few discoveries of metals before the industrial age where an important development occurs for

to different elevated temperature. MIP (Mercury intrusion porosimetry) test was conducted to estimate the pore diameter and also to appreciate the change of total pore volume due to change of exposure temperature. SEM (Scanning electron microscopy) study was also done to appreciate the micro-structural change in recycled aggregate concrete.

of our solar system. It contains almost all of the mass in our solar system and exerts a tremendous gravitational pull on planets and other bodies. 3. Our solar system formed about 4.6 billion years ago. 4. The four planets closest to the Sun - Mercury‚ Venus‚ Earth‚ and Mars - are called the terrestrial planets because they have solid‚ rocky surfaces. 5. Two of the outer planets beyond the orbit of Mars - Jupiter and Saturn - are known as gas giants; the more distant Uranus and Neptune are called

This experiment aims to demonstrate the particle nature of light by photoelectric effect. Stopping potential was measured against different intensities of yellow (λ = 578 nm) and green (λ = 546 nm) light from first order spectral lines of mercury. No significant relationship was observed for stopping potential and percent transmission. However‚ charging time was inversely proportional to the percent transmission for the yellow light which implied more photoelectrons were emitted for greater

relied on inelastic scattering of electrons inside the tube. Low pressure mercury vapor is injected into the tube. When the tube is connected to electricity‚ electrons emitted from the tube by the high temperature filament. The electrons moving in collide with the mercury atoms. Such collisions transfer kinetic energy in electrons to the mercury atoms. By absorbing this extra energy‚ the outermost shell electron in mercury atoms jump to a higher energy state‚ which is unstable to stay. A photon is
