How does the data provide evidence for the formation of ocean currents? The data shows that different areas of the ocean have water at different depths, Influencing the global
movement of water in the ocean currents
o The data shows that different areas of the ocean have water with similar salinity, influencing the global
movement of water in ocean currents.
The data shows that water from different areas of the ocean has different densities, influencing the global
movement of water in ocean currents.
o The data shows that water from different areas of the ocean has similar temperatures, influencing the global
movement of waster in ocean currents

i don,t know so just answer mine

the answer is d.) potassium

(newtons first law)

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied
