A car is accelerating from rest at a rate of 2 (m/s)/ s. How fast will it be going after 4 seconds?

8 m/s

Explanation:

The Formula

v = u + at

⇒ v = final velocity

⇒ u = initial velocity

⇒ a = acceleration

⇒ t = time taken

Given

u = 0 [rest]a = 2 m/st = 4 s

Solving

v = u + atv = 0 + 2(4)v = 8 m/s

Ch4 and ph3 are both covalent since they are composed both of non-metals.    ch4 is non- polar because of  london forces and has a geometry of tetrahedral  ph3 , on the other hand, is umbrella shaped polar and has dipole-dipole intermolecular force (imf) . since ph3 is polar, it has a stronger imf   

Idon’t know what the answer is i wish i could
