If the pressure above a solution containing a gas solute is reduced, the limit of the gas's solubility will decrease.
Answer:
Explanation:
a ) The earth rotates by 2π radian in 24 x 60 x 60 s
so angular speed ( w ) = 2π / (24 x 60 x 60) = 7.268 x 10⁻⁵ rad / s
b ) Linear speed of city of Arlington ( v ) = w r = w R Cosλ where R is radius of the earth and λ is latitude .
v = 7.268 x 10⁻⁵ x 6.371 x 10⁶ cos 32.7357
389.5 m /s
acceleration = w² r = w² R Cos 32.7357
= (7.268 x 10⁻⁵ )² x 6.371 x 10⁶ x cos 32.7357
=283.08 x 10⁻⁴ m/s²
c) velocity ratio =
w r /w R =
R cos 32.73/ R
= Cos 32.73
= 0.84 .
decay series consists of radioactive nuclides produced by
successive radioactive decay until a stable nuclide is reached. (…)
Answer:
Option (d)
The angular momentum of the system is 5 Kg-m²/s
Explanation:
Angular momentum: Angular momentum is the product of angular velocity and of moment of inertia.
Angular momentum is dented by L
And the unit of angular momentum is Kg-m²/s
L= I×ω
I is momentum of inertia
ω is angular velocity.
The unit of angular velocity is red/s.
Momentum of inertia : Momentum of inertia is the sum square the perpendicular distance from the rotational axis to of product mass of each particle of the body.

The S.I unit of momentum of inertia is kg-m²
The angular momentum of a system is:
L= ∑I ω
=∑ Mr²ω [ Since
]
Given , M= 1 kg, r₁=1 m , r₂= 2 m and ω = 1 rad/s.
The angular momentum of the system is
L= Mr₁²ω+Mr₂²ω
= Mω(r₁²+r₂²)
= {1×1 (1²+2²)}
=5 Kg-m²/s
