Group 0 - they are called the NOBLE GASES
(as they're very unreactive) because...
ALL of their atoms are full.
Example : Helium contains 2 electrons so it's outer shell is full
Answer:
Explanation:
tangential acceleration at = 3.1 m / s²
angular acceleration = tangential accn / radius
= 3.1 / r , r is radius of the cylinder .
IF N₁ be no of rotation in time t
θ = 1/2 α t² , α is angular acceleration , θ is angle in radian covered in time t
2π N₁ = 1/2 (3.1 / r ) x 2.9²
N₁ = 2.0757 / r
similarly we can calculate
2πN₂ = 1/2 (3.1 / r ) x 10²
N₂ = 24.68 / r
N₂ / N₁ = 11.89
Ohm’s Law states that electrical current is proportional to voltage and therefore inversely proportional to resistance - V = I x R
Elliptical, as shown by most projections
Weight equals mass multiplied by the acceleration due to gravity.
