A helium tank holds a volume of .02 m^3 at a pressure of 15.5*10^6 Pa and a temperature of 293 K. How many spherical balloons wi
lukranit [14]

Answer:

Explanation:

We shall find the volume of stored gas at atmospheric pressure .

P₁ V₁ = P₂ V₂

15.5 x 10⁶ x .02 = 10⁵ x V₂  ( atmospheric pressure is 10⁵ Pa )

V₂ = 3.1 m³

volume of one balloon = 4/3 x π r³ , r is radius of balloon

= 4/3  π x .11³

= .050658 m³

no of balloon = total volume to be filled / volume of one balloon

= 3.1 / .050658

= 61 .2

= 61

IRISSAK [1]

Answer:

Explanation:

Impulse of a force is measured by force x time or F X t

Impulse also equals change in momentum or

F x t = m v₂ - m v₁

The given case is as follows

in the first case

F x t = mv - o = mv

F = mv / t

in the second case

F₁ x 4 t = mv

F₁ = 1/4 x mv /t

F₁ = F / 4

option a) is correct .

iii )

In the last case

F₂ X t = m v/2 -0

F₂ = 1/2 x mv / t

= 1/2 x F

F₂ = F/2

Option e ) is correct.
