Answer:
Diffusion
Explanation:
This process can be referred to as diffusion. The cold air moves from a region of high concentration (outside) to a region of low concentration (inside). The movement of these cold air is what is referred to as "letting in cold air".
NOTE: Diffusion is the process in which substances move from a region of high concentration to a region of low concentration. Just like when an insecticide is sprayed inside a closed room and then the room is later opened so as to allow the the sprayed insecticide leave the room.
Answer:
sum of these two vectors is 6.06i+3.5j-3.5i+6.06j = 2.56i+9.56j
Explanation:
We have given first vector which has length of 7 units and makes an angle of 30° with positive x-axis
So x component of the vector 
y component of the vector 
So vector will be 6.06i+3.5j
Now other vector of length of 7 units and makes an angle of 120° with positive x-axis
So x component of vector 
y component of the vector 
Now sum of these two vectors is 6.06i+3.5j-3.5i+6.06j = 2.56i+9.56j
