Homework Statement Consider n moles of ideal gas kept in a cylinder with a piston. Two heat reservoirs 1 and 2 with the temperatures T1 < T2 are available, and at any given moment of time the heat exchange is established with only one of the reservoirs. In the initial equilibrium state the...

Ahh! i see... so if we consider the total number of products to be 100 then we have 28 objects of 45g...and 72 objects of 55g so Therefore Total Weight = (28 x 45) + (72 x 55) = 5220g Therefore the average weight = 5220/100 = 52.20g

Simple Math Problem! If 28% of the objects in a box weighed 45 gm each and 72% of the objects in a box weighed 55 gm each, what is the average weight of the object. ----- The Average Weight of the Object = Total Weight / Total No. of Objects Total No objects 45gm => 45/x = 0.28 => x =...

Ok the question is some what simple and difficult. I know there are certain rules like a. A + B = AB (combination) b. AB = A + B (decomposition) c. AB + C = CB + A (substitution) d. AB + CD = AD + CB (metathesis) now the trouble i have is not in balancing the equation but figuring out...

Well according to your hint and from what i have learned the clay changes its shape and the energy is lost in the form of heat ad sound...

Collision occurs when 2 objects move towards each other with some force so... What i was trying to say is the " K.E in case of inelastic collision is lost by means of transfer from a high K.E object to a low K.E object thereby making the low K.E object move in the same direction as that of the...

Homework Statement In an elastic collision of 2 objects, Kinetic energy is conserved. In an inelastic collision it is not. Where does the kinetic energy "go" in an inelastic collision ? Homework Equations None The Attempt at a Solution Ok i am not sure of the answer but is it...

Thanks a lot !

Air Puck ! Correct Method or not... Homework Statement An air puck of mass 0.25kg is tied to a string and allowed to revolve in a circle of radius 1.0m on a frictionless horizontal table. The other end of the string passes through a hole in the center of the table and a mass of 1kg is tied...

Thanks! worked out right...

Centripetal Acceleration ! Homework Statement An Engineer wishes to design a curved exit ramp for a toll road in such a way that a car will not have to rely on friction to round the curve without skidding. He does so by banking the road in such a way that the force causing the centripetal...

Thanks ! Understood...

Clarification about friction equation ! Homework Statement Suppose there is an object on the top of a ramp at a rest would these equation/s be correct to preform calculations considering friction applies \SigmaF_y = n - (m * g * Cos\Theta) = 0 \SigmaF_x = (m * g * Sin\Theta) - (\mu_s *...

so in other words are you trying to say (a) Determine the Net Force acting on the system...is the same thing as finding the tension...?

Ok i revised all my calculation and came up with this attempt i assuming that (b) is right from my attempt i would calculate (c) as below http://img151.imagevenue.com/loc682/th_98713_dig_122_682lo.jpg For mass 1 \SigmaF = m_1 * a T - W1 = m_1*a T - (m_1*g) = (m_1*a) ------(3) For mass 2...
