2objects each of mass 1.5kg are moving in the same straight line but in the opposite directions. the velocity of each object is 2.5m/s before collision, during which they stick together. what will be the velocity of combined object after collision?

0 m/s

Explanation:

Momentum before = momentum after

m₁ u₁ + m₂ u₂ = (m₁ + m₂) v

(1.5 kg) (2.5 m/s) + (1.5 kg) (-2.5 m/s) = (1.5 kg + 1.5 kg) v

v = 0 m/s

cell differentiation  is how generic embryonic  cells  become specialized  cells. this occurs  through a process called gene expression. gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a  cell  functions.

explanation:

small = small current large mag large current
