Tea gets cool beacuse of heat tranfer through convenction
Heat transfers from a area of hot region to cold.
The tea is hot in this case, due to taht factor the heat will move towards teh cooler region which is coke and will make the coke warm


Hope this helped!

A beaker contains 450g of water at a temperature of 24C, The therman capacity of the beaker is negligible and no heat is gained
valentina_108 [34]
Given:

450 grams of water (Tw = 24 C) 
Thermal capacity of the beaker = negligible
Q = 0 
Tice = 0 C
Tfinal = 8 C

450g * (Tf - Tw) + m_ice * (Tice - Tw) = 0

450g * (8 - 24) + m_ice (0 - 24) = 0 

solve for m_ice

THE NUMERICAL RATIO OF DISPLACEMENT TO DISTANCE IS:​
Tamiku [17]

There's no general rule.  

Displacement is the length of a straight line from start to finish, and distance is how far you actually traveled from start to finish.

The only thing we really know is that distance can never be shorter than displacement.  So I guess the answer is:

<em>The numerical ratio of displacement to distance is always 1 or less</em>.

(But it has to be written ALL IN CAPITALS.)

The quantity of charge through a conductor is modeled as Q = (3.00 mC/s4)t4 − (2.00 mC/s)t + 9.00 mC. What is the current (in A)
Mumz [18]

Answer:

The current at time t = 4.00 s is 0.766 A.

Explanation:

Given that,

The quantity of charge through a conductor is modeled as :

Q=(3t^4-2t+9)\ mC

We need to find the current (in A) at time t = 4.00 s. We know that the rate of change of electric charge is called electric current. It is given by :

I=\dfrac{dQ}{dt}\\\\I=\dfrac{d(3t^4-2t+9)}{dt}\\\\I=12t^3-2

At t = 4 s

I=12(4)^3-2=766\ mC/s\\\\I=0.766\ C/s=0.766\ A

So, the current at time t = 4.00 s is 0.766 A. Hence, this is the required solution.
