Explanation:
Velocity is equivalent to speed but it considers the direction of the object. Velocity is also calculated by dividing the distance travelled by time. Therefore, where d and t are distance and time respectively. Given that d is given as 350 m and t is 1.4 s then by substitution
and the direction is down the road.
Velocity is 250 m/min down the road

The value is
Explanation:
From the question we are told that
The volume of liquid nitrogen is
The density of nitrogen at gaseous form is = The dry air at sea level
Generally the density of nitrogen at liquid form is
And this is mathematically represented as
=>
Now the density of gaseous nitrogen is
=>
Given that the mass is constant
=>
