Answer:
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
=>
Answer:
sometimes sunset could sometimes cause a pink and orange cloud
1) Vf = Vo - gt; Vf = 0 => Vo = gt = 9.8m/s^2 * 1.5s = 14.7 m/s
2) d = Vo*t - gt^2 /2 = 14.7m/s*1.5 - 9.8m/s^2 * (1.5s)^2 / 2 = 11.02 m
Answer:
Potential energy =mass* acceleration due to gravity * height
mass*acceleration due to gravity =weight
hence potential energy of the puppy= weight * height
=18*2
=36 joule
