Answer:
1.The S.I unit of speed is meter/sec .The bigger unit is Km/hr .
2.Yes, the car is accelerating .
The car is moving with constant speed but at the same time ,it is changing its direction continuously: This refers to non-uniform velocity which further give rise to acceleration.
Acceleration is rate of change of velocity .
3.Speed is defined as distance traveled in a given time .Therefore it can be calculated as : Speed =Distance /Time .
4.Total distance traveled = 105 Km /hr .
This is an example of speed .
The reason being they have not specified the direction in which car is travelling .The only difference between velocity and speed is the mentioning of direction because speed is scalar quantity and velocity is vector .physical quantity .
5.Acceleration can be calculated as : Change of velocity /time

Answer:
The answer to your question is:letter A
Explanation:
Data
Density = mass/ volume
In the graph we can observe that if the temperature increases 4°C, then density increases but if the temperature increases more than 4°C density diminishes.
Then as density = mass / volume
For the first part (0 - 4°C) volume diminishes and density increases.
For the second part ( 4 - 12°C) volume increases and density diminishes.
If you need to choose only one answer it would be letter A.
If you need to choose two answers, they would be A and B
