it is the change in speed over time. So  a = v-u / t

²⁰⁸₈₃Bi ==> ^x_yZ + ⁴₂a + ⁴₂a + ⁰₁B x = 208 - 8 = 200 y = 83 - 5 = 78 Proton number = 78 ther...

E_k = (1/2)mv²

E_p = mg(dh)

Set these equal to each other, because of conservation of energy:

(1/2)mv² = mg(dh)

Cancel the mass:

First: an object remains at rest or constant speed unless acted on by an external force

Second: Force is equal to rate of change of momentum

Third: Every action has an equal and opposite rea...

When coherent, in-phase light passes through two slits they act as seperate sources, these waves diffract and overlap, causing regions of constructive and destructive interference. When they collide with ...
