उत्तर : 3. "Specific Heat formula"
व्याख्या :
Answer: C) Specific Heat formula Explanation: Q = mc∆T refers to Specific Heat formula. When heat energy is added to a substance, the temperature will change by a certain amount. The relationship between heat energy and temperature is different for every material, and the specific heat is a value that describes how they relate. Q = mc∆T Q = heat energy (Joules, J) m = mass of a substance (kg) c = specific heat (units J/kg∙K) ∆T = change in temperature (Kelvins, K)

उत्तर : 2. "= 0.6. Are these two events are disjoint ?
A) TRUE
B) FALSE
Answer & Explanation
Answer: B) FALSE
Explanation: These two events cannot be disjoint because P(K) + P(L) > 1.
P(AꓴB) = P("
व्याख्या :
Answer: B) FALSE Explanation: These two events cannot be disjoint because P(K) + P(L) > 1. P(AꓴB) = P(A) + P(B) - P(AꓵB). An event is disjoint if P(A ꓵ B) = 0. If K and L are disjoint P(K ꓴ L) = 0.8 + 0.6 = 1.4 And Since probability cannot be greater than 1, these two mentioned events cannot be disjoint.
