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!
In a block and tackle, some friction in the pulleys will reduce the mechanical advantage of the machine. To include friction in a calculation of the mechanical advantage of a block and tackle, divide the weight of the object being lifted by the weight necessary to lift it.

The statement is false because as the temperature of water is decreased from 4C to 0C, <em>expansion</em> occurs.
You should understand that this is very weird behavior for any compound ... within a small temperature range, the stuff actually gets bigger as it gets colder. That's why cubes float in your sody, and bergs float in the ocean.
Water is one of only two known substances that do this. And if water didn't do it, then life on Earth would not be possible.

Answer:
Magnitude of vector A is 51.4 m
The angle of vector A with positive x-axis is θ= 
Explanation:
Given is
=-31m
=41m
Let and are components of a vector A,
The magnitude of vector A will be:
= 
A = 51.4 m
we know
θ1= 
= 
=
Vector A is present in 2nd quadrant as x-component of vector A is negative and y-component is positive.
For finding the angle of vector with positive x-axis,
θ=180-52.9
θ=
