In a collision, the second collision is when an unsecured driver strikes the inside of the vehicle. It is a collision that happens between an occupant of a vehicle and the vehicle he is riding during the impact. The first collision would be the collision of the vehicle and the other object.
It would be A. 37.5 because if you multiply 50 and 15 it would be 750 then divide 20 it gives you 37.5.
Explanation:
The unit of volume derived from SI units(1) is the cubic meter, m3.
Chemists in a laboratory usually deal with much smaller volumes than cubic meters and the metric but non-SI units of liter or litre (L) and milliliter or millilitre (mL or ml) are in common use.
In 1964 the litre was redefined as being equal to exactly 1 cubic decimetre:
1 L = 1 dm3
So 1 milliltre = 1 cubic centimetre
1 mL = 1 cm3 (= 1cc)
Other metric units of measuring volume are given in the table below:

Answer:
C = 74.53°
Explanation:
Let the magnitudes of 5.00 and 9.00 be vectors A and B respectively, hence the dot product of this vector is defined as
A.B = |A||B|cosC; let C be the angle between the vectors
12 = 5×9 cos C
Hence cos C = 12/45
C = cos^-1(12/45)
C = 74.53°
