In the problem, we are asked to identify the appropriate si units for each given item.
00:08
So for letter a, the appropriate unit is second because in this item, we need to measure time.
00:23
The time it takes for a cd to play is around a certain number of minutes, which can be converted into seconds.
00:35
For letter b, the appropriate unit is kilogram, because this is the si unit for mass, and the car is quite massive.
00:48
So kilogram is appropriate.
00:51
Then for letter c, the appropriate unit is meter, because it is the si unit for length, and those soccer fields are quite wide.
01:06
So it's still small for a kilometer.
01:09
So meter would be the appropriate unit.
01:16
For letter d, the appropriate unit would be centimeter.
01:26
Because again, we're talking about length here.
01:31
And pizzas are quite small in size.
01:35
So meter cannot be used.
01:38
So it should be in centimeter.
01:43
For letter e, the appropriate unit is gram...
