1 mm Hg pressure is the pressure due to 1 mm height of mercury

so it is given as

P = \rho g h

P = 1 * 10^{-3} * 13700 * 9.8 = 134.26 Pa

now we know that pressure is

P = 405 kPa

P = 405 * 10^3 Pa

so in mm Hg this pressure is

P = \frac{405 * 10^3 }{134.26} = 3016.5 mm Hg

so pressure in millimeter Hg will be 3016.5 mm Hg

An object is released from rest at time t = 0 and falls through the air, which exerts a resistive force such that the accelerati
lubasha [3.4K]

Answer:

The correct option is

a. v = g (1-e^{-bt})/b

Explanation:

Time at which the object start fall t = 0

The acceleration a is given by a = g - bV

Where V = Speed of the object

Speed V² = u² + 2·a·h

However with the drag force the object will approach terminal velocity as t becomes progressively larger whereby v will stop increasing

Option a. is the only option that has  limiting value of v which is in the range of g as t increases ∴ option a. is the correct option.

v = g (1-e^{-bt})/b  as t increases (1-e^{-bt}) → 1 s and v→ g/b m/s

Which evidence is lost likely used to indicate the beginning of solar system formation?
deff fn [24]

Explanation :

Our solar system was formed about 4.6 billion years ago. It is formed when gravity exerted low-density cloud of interstellar gas and dust. The massive cloud of gas and dust is called as Orion Nebula.  

In a small area, the overdensity of clouds occurs. This caused the contraction, to begin. Due to this contraction the potential energy gets converted into kinetic energy of individual gas particles.

Hence the correct option is " materials were pulled together by the gravity". This is the one of the evidence used to indicate the beginning of the solar system.
