  • Question #21c71 - Socratic
    Using, # (x+y)^3=x^3+y^3+3xy (x+y)#, we get from # (square)#, # (sin^2A)^3+ (cos^2A)^3+3sin^2Acos^2A (sin^2A+cos^2A)=1#, #: sin^6A+cos^6A+3sin^2Acos^2A (1)=1, or, #,
  • Question #b5f73 - Socratic
    Then, we can just find the mass of 2 272 carbon atoms by multiplying 2 272 by the mass of 1 mole of carbon: 2 272 xx 12 01 = "27 29g" Since there was 1 significant figure in the question, our answer is "30g" Another way to solve this problem is by using the mass percent!

  • Question #6f7d1 - Socratic
    675N Here,the kinetic energy of the hammer head got totally converted to the work done in moving the nail through a distance of 10 mm or 0 01 m So, kinetic energy of the hammer during the strike was 1 2 m v^2=1 2×1 5×3^2=6 75J Now,if an average force of F had acted on the nail to move it by 0 01 m,then work done by the force will be (F×0 01)J(using W=F*s) So,we can equate both 6 75=F×0 01
