Pace Count is a way to measure to Ground Distance. Pace Count is nothing but regular single natural step of about 30 inches long.

Answer: D) 24 Explanation: Let the integer be x. Then, x2 - 20x = 96 (x + 4)(x - 24) = 0 x = 24

Answer: B) 138 Explanation: The gram formula mass of a compound is nothing but the molar mass. The molar mass of K2CO3 (Potassium Carbonate) is given by Atomic weights of individual elements are   K (Potassium) = 39 g C (Carbon) = 12 g O (Oxygen) = 16 g   Hence, that of K2CO3 = 39(2) + 12 + 16(3) = 78 + 12 + 48 = 138.

Answer: A) General Data Protection Regulation Explanation: GDPR stands for the General Data Protection Regulation.

Answer: D) 12 6/7 days Explanation: Let 'B' alone can do the work in 'x' days 6/30 + 18/x = 1 => x = 22.5   1/30 + 1/22.5 = 7/90  => 90/7 = 12 6/7 days

Resistivity : Resistivity is a measure of the resistance to the flow of electrons.  Conductivity : Conductivity is just the inverse of resistivity, σ = 1/ρ, where σ is conductivity and ρ is resistivity.   Example: Think of a pipe and water, the bigger the pipe, the easier water can flow and thus the lower the resistance.
