Answer:
You can separate a mixture of sand, salt and water by decantation and evaporation. Decantation will separate sand from salt and water. Sand remains in the original vessel, whereas salt and water is transfered to new vessel. Evaporation will separate salt from water.
Answer:
The ball hit with 12 N
Explanation:
acceleration = Force/ mass
If masses of balls are the same, then more the force - more acceleration.
12N more than 8N,
so the ball that hits Stacy accelerate faster.
The mean mass of the given sample is 39.12g
- The mean is the average of the values in the given set. It indicates that values in a particular data set are distributed equally.
mass of first sample = 39.75g
mass of second sample = 38.91g
mass of third sample = 37.66g
mass of fourth sample = 39.75g
mass of fifth sample= 39.55g
Total mass of the sample = 39.75 g + 38.91 g+ 37.66 +39.75 g + 39.55 g = 195.62 g
Number of samples = 5
- MEAN = SUM OF MASS OF GIVEN SAMPLES / TOTAL NUMBER OF SAMPLE
- = 195.62/5
- = 39.12g
Therefore mean mass of the samples = 39.12g

Answer:
300 servings
Explanation:
there are 1000mgs in every gram so divide that by 100 to get the servings which is 10 then multiply it by 30 , once for each gram. and you get 300.
