Im not doing the math-
BigorU [14]
The average speed of the blocks are 0.36 m/s.
Explanation:
Average speed is defined as the ratio of distance covered per unit time. So if it is said that blocks are pulled to 0.9 m in the right side. This means the blocks cover a distance of 0.9 m from the origin and that distance is covered in 2.5 s. Thus, the average speed can be calculated from the change in speed with respect to time. As at time t = 0 , the speed is also zero, and at time t = 2.5 s , the speed will be
Since, in this case, the speed is equal to the average speed of blocks. So the average speed of the blocks will be 0.36 m/s.

How mariy molecules of water are in a 500.3 g sample?
JulijaS [17]

Answer:

1.67×10^25 molecules

Explanation:

No of molecules = no of moles × Avogadros number

No of moles= mass in gram / molar mass

No of moles of water in given sample = 500.3/18

= 27.79 moles

No of molecules = 27.79× 6.02×10^ 23

= 167.32×10^23 or 1.67×10^25
