volume of milk is given as
we will convert it into mL unit
mass of the milk m = 2kg
m = 2000 g
now for the density we can use
<em>so the density is 0.264 g/mL for above sample</em>
Answer:243joules
Explanation:
Mass(m)=54kg
Velocity(v)=3m/s
Kinetic energy =(m x v^2)/2
Kinetic energy =(54 x 3^2)/2
Kinetic energy =(54 x 9)/2
Kinetic energy =486/2
Kinetic energy =243joules
To find 
we need to use vector addition and use the x and y components. First we subtract vector 2 from vector 5 which results in a vector with a length of 3 pointing directly east, then we use the distance formula to find the length of the net force 
which gives 
. We now have a magnitude but we also need a direction, since vector 4 and vector 5 are perpendicular. Using 
where tan^-1(y/x) we get an angle of 53 degrees. The resultant force vector is 5 distance with an angle of 53 degrees north east.
Factors that affect heat transfer are:
1) Difference in temperature,
2) Mass of the object
3) Specific heat of the object
Hope this helps!
