Explanation of Solution
Given info: The mass of ice is
Three processes are takes place in the conversion of ice to water. Fist ice should be raised from its initial temperature to
In different stages, the heat capacity will be different. In the intermediate stage during phase change it is required to consider the latent heat of fusion.
Conclusion:
No, before melting the temperature of ice should from

- You're on an interplanetary mission, in an orbit around the Sun. Suppose you make a maneuver that brings your perihelion in closer to the Sun but leaves your aphelion unchanged. Then you must have Question 2 options: sped up at perihelion sped up at aphelion slowed down at perihelion slowed down at aphelionarrow_forwardThe force of the quadriceps (Fq) and force of the patellar tendon (Fp) is identical (i.e., 1000 N each).
