1. ### If ED = √8 cm and the area of ∆ABC = trapezoid ACDE, the length of AC is?

AC = 2.  See below for explanation. Notice that there are two similar triangles, ABC and EBD.  The area of EBD is twice that of ABC, since the trapezoid area is equal to that of triangle ABC. But, the square...

3. ### What would happen if 1 cm ^3 of matter from the center of the sun instantly appeared at the surface of the earth?

Not much. No fusion or anything (once isolated, at Earth pressure, it would cool down). So the main effect would be the transfer of heat energy. That 150 g of hydrogen at 15 millions degrees. So 0.15 × 15×10⁶ × 14×10³ = 31.5...

4. ### A steel cylinder holds 1.50 g of ethanol. What is the pressure of the ethanol vapor if the cylinder has a volume of 251 cm ^3 ?

moles ethanol = 1.50 g / 46.07 g/mol = 0.03256 mol PV = n RT P = nRT/V P = 0.03256 mol (0.08206 Latm/molK) (523 K) / 0.251 L P = 5.56 atm If you need pressure in a different unit, just use the R that...

6. ### Pair of closely spaced square conducting plates measure 14 cm on a side. The electric-field energy density between the plates is 5.5 kJ/m^3?

density µ = E² / ε₀ so E² = µ*ε₀ = 5500J/m³ / 8.85e-12 C²/N·m² = 6.2e14 N²/C² E = 2.5e7 N/C then E = σ / ε₀ = Q / Aε₀ Q = EA...

7. ### a piece of wire x cm is to be cut into two and make a square from it. the length of one side of one square is 12 times the length of the ot?

it is formed into two squares? basically, if z is one piece and y is the other z + y = x sides of each are z/4 and y/4 areas are z²/16 and y²/16 sum is z²/16 + y²/16 12(z/4) = y/4 12z = y x = z + y = z + 12z = 13z...

8. ### A long, solid rod 5.7 cm in radius carries a uniform volume charge density?

I think we can use field E = λ / 2πrε₀ to find the linear charge density 20e3 N/C = λ / (2π*0.057m*8.85e-12 C²/N·m²) λ = 6.34e-8 C/m The rod has a cross-sectional area A = πr² = π(0.057m)² = 1.02e-2 m² and so the...

10. ### What pressure is exerted at the bottom of a tube of mercury 15- cm high? With Mercury’s density being 13,600 kg/m3. ?

pressure due to mercury pi = 0.15*13.6*9.807 = 20.0 kPa atmospheric pressure patm = 0.76*13.6*9.807 = 101 kPa total pressure p = pi+patm = 101+20.0 = 121 kPa  or more simply : p = 0.76*9.807*(0.76+0.15) = 121 kPa
