1. a metal ball with mass m1 = 4 kg is heated to a temperature of θ1 = 186.7 degrees celsius, after which it is introduced into a calorimeter of negligible caloric capacity and containing a volume v2 = 6 liters of water at θ2 = 10 degrees celsius. after establishing the equilibrium, the temperature of the system is θ = 20 degrees celsius. neglecting heat losses, the specific heat of the ball is present.

2. a nickel body with mass m1 = 0.8 kg and initial temperature θ1 = 950 degrees celsius is introduced into a vessel with mass m2 = 50 kg water at temperature θ2 = 16 degrees celsius. let the equilibrium temperature be found. losses of any kind are neglected.

Choose the most likely outcome of this scenario: jen decided to go bike riding without a helmet. while no one is around during her ride, she is thrown from her bike when her wheel goes into a pothole. she is not injured, but she is terrified to get back on her bike. what happens next? a. her physical health is affected even though she wasn't hurt. b. her mental and emotional health are affected because she is afraid to get back on her bike. c. her social health is affected because she is worried her friends saw the fall. d. her overall health is not affected at all by her fall.

An isolated conducting spherical shell carries a positive charge. part a which statement (or statements) about the electric field and the electric potential inside and outside the spherical shell is correct? which statement (or statements) about the electric field and the electric potential inside and outside the spherical shell is correct? electric potential inside the shell is constant and outside the shell is changing as 1/r2 both the electric potential and the electric field does change with r inside and outside the spherical shell electric potential inside and outside the shell is constant, but not zero electric potential inside the shell is constant and outside the shell is equal to zero electric field inside and outside the shell is constant (does not change with the position r), but is not equal to zero electric field inside and outside the shell is changing as 1/r (where r is the distance from the center of the sphere) electric field inside is equal to zero and outside the shell is constant, but not zero electric potential inside the shell is constant and outside the shell is changing as 1/r electric field inside and outside the shell is changing as 1/r2 electric field inside is equal to zero and outside the shell is changing as 1/r2 electric field inside and outside the shell is zero electric field inside is constant and outside the shell is changing as 1/r
