A calorimeter has a heat capacity of 60J/°C. 0.15kg of water at 20°C is contained in the calorimeter. 1kg of the same liquid at 90°C is added, and the final temperature of the mixture is 45°C. Calculate the specific heat capacity of the liquid.

Write maxwell's equations and discuss the terms involved and the results of each equation in classical electrodynamics. if it is possible to write these equations in integral form, give the integral forms. find the wave equation for electromagnetic waves from the maxwell equations. what is the propagation velocity of electromagnetic waves in space according to the wave equation you find?

What tightening torque should be used for a hexagonal head screw (not split-bolt) on a 250 kcmil conductor?

Awater balloon launcher uses an elastic band with a spring constant of 115 n/m to use thee launcher you stretch thee band back with a balloon n it the water balloons have a mass of 1.3 kg a) if you stretch the band by 0.8 m, what elastic force will the band exert? b) with the band stretched 0.8 m, how much elastic potential energy is stored in the spring? c) if you release the band, it pushes forward. what is the kinetic energy of the balloon when it reaches the natural length of the band? d) what is the speed of the balloon when it reaches the natural length of the band?
