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...

Most construction projects in the US start work at 7 a.m. and end work at around 3 or 3:30 p.m. What you do after that is your own business.

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...

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...

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...

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...

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
