A thermos contains m1 = 0.89 kg of tea at T1 = 31° C. Ice (m2 = 0.075 kg, T2 = 0° C) is added to it. The heat capacity of both water and tea is c = 4186 J/(kg⋅K), and the latent heat of fusion for water is Lf = 33.5 × 104 J/kg. show answer No Attempt 50% Part (a) Input an expression for the final temperature after the ice has melted and the system has reached thermal equilibrium. Part (b) What is the final temperature in Kelvin?

a)

b) 295.52K

Explanation:

a) you use the following formula:

   ( 1 )

m2: 0.075kg

m1: 0.89kg

Lf= 33.5 × 104 J/kg

Ti2= 0C=273.15K

Ti1 = 31C = 304.15K

Then, you obtain T from the formula (1):

b) By replacing the values of all parameters you obtain:

f=ma newton

f=100x2.5=250n

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
