Yes, it can be unicellular and multicellular
Answer:
her acceleration is 1 m/sec
Explanation:
The following information is given in the question
The initial velocity is 5 m/s
After 10 seconds, she would be moved at 15 m/s
We need to find the acceleration
As we know that
Acceleration = Change in speed ÷ time
Acceleration = (15 - 5) ÷ (10)
= 1 m/sec
Hence, her acceleration is 1 m/sec
The same would be considered
Density I'm not sure
volume unchanged
mass unchanged
shape- water
Answer:

Explanation:
As we know that mass is the product of volume and density
so we will have

here we have

so we will have

so we will have


now let the position of Pluto is at origin so we have
