A car start from rest and covers distance of 100m after 10seconds. if the acceleration is 2m/s square, calculate the final velocity..​

20 m/s

Explanation:

solution,

initial velocity (u)=0 m/s

Distance covered(s)=100m

Time taken(t)=10 seconds

Acceleration (a)=2m/s²

Now,

By using first equation of motion, we have

v=u+at

=0+2×10

=20 m/s

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
