Answer:
19 x 85 = 1,615 for distance. Displacement is 0
Explanation:
The total distance traveled by the ant in 9 round trips and one 1/2 trip, or 19 one bash way trips: 19 x 85cm = 1615cm. The displacement of the ant after the tenth trip is 0 cm ( the displacement origin is the nest.)
100 as momentum=mass×velocity
21+10=31 because you can see that 21 and 10 are in metres while 12 is in seconds so 21+10=31 is the answer.
Answer:
B.
Explanation:
K is the SI unit for Kelvin which measures temperature.
kg is NOT an SI unit, g is the SI unit for mass.
L is NOT an SI unit, m^3 is the SI unit for volume.
Therefore the answer is B.
