A0.011 kg cube of ice at 0.0°C is added to 0.450 kg of soup at 80.0°C. Assuming that the soup has the same specific heat capacity as water, find the final tempera- ture of the soup after the ice has melted. (Hint: There is a temperature change after the ice melts.) pls with explanation

An electron and a proton are held on an x axis, with the electron at x = + 1.000 m and the proton at x = - 1.000 m. part a how much work is required to bring an additional electron from infinity to the origin? express your answer with the appropriate units. part b if, instead of the second electron coming in from infinity, it is initially at x = + 20.00 m on the axis and is given an initial velocity of 100.0 m/s toward the origin, does it reach the origin? part c how close to the origin does it come?
