All u have to do is see how much mass the rover has, and then multiply that value by 3.71
Answer:
-Use of magnet
-Mixing in water
Explanation:
Two ways are;
1) Use of magnet: Nails are made of steel and thus can be attracted by magnets. So when a magnet is put inside the mixture, it attracts the magnet out.
2) Mixing it in water: When it is put in water, the nails will go to the bottom while the saw dust will float on the water.
Since the density of water is 1g/cm^3, The mass of water needed to fill the tank is 150000 grams
Answer:
Displacement is 50 m
Explanation:
Distance is simply the measurement of the sum of all paths travelled.
Thus, since he swims the 50m length pool 3 times, then the total distance = 50 × 3 = 150 m
Whereas, displacement is the measurement of length of the shortest path from initial point to final point.
In this case initial point to final point is 50m. Thus, the displacement is 50 m
