Jean Piaget was a cognitive psychologist who identified four stages of development: the sensorimotor stage from birth to 2 years, the preoperational stage from age 2 to age 7, the concrete operational stage from age 7 to 11, and the formal operational stage from age 11 to adult. He identified milestones that occur at each stage.   According to Piaget, the main task of the sensorimotor stage is for the child to learn the concept of object permanence, use senses and motor skills to understand the world.

Answer: A) 4 : 5 Explanation: Let x be the investment of Lasya in 5% and y be in 4% x(5)(n)/100 = y(4)(n)/100 => x/y = 4/5 x : y = 4 : 5

The interviewer is attempting to assess how closely your ideal fits with the reality of their organisation. A positive work environment makes employees feel good about coming to work, and this provides the motivation to sustain them throughout the day.

Answer: A) 2000 Explanation: Let 's' be the number of small packets and 'b' the number of large packets sold on that day.   Therefore, s + b = 5000 ... eqn (1)   Each small packet was sold for Rs.150.Therefore, 's' small packets would have fetched Rs.150s.   Each large packets was sold for Rs.250.Therefore, 'b' large packets would have fetched Rs.250b.   Total value of sale = 150s + 250b = Rs. 10.5 Lakhs (Given)   Or 150s + 250b = 10,50,000 ... eqn (2)   Multiplying equation (1) by 150, we get 150s + 150b = 7,50,000 ... eqn (3)   Subtracting eqn (3) from eqn (2), we get 100b = 3,00,000Or b = 3000   We know that s + b = 5000So, s = 5000 - b = 5000 - 3000 = 2000.   2000 small packets were sold.

Answer: A) 50.0 mL 0.0500 M calcium hydroxide, Ca(OH)2 (aq) Explanation: 50.0 mL 0.0500 M calcium hydroxide, Ca(OH)2 (aq) has the highest pH value. Sodium hydroxide and Calcium hydroxide are strong bases so they completely ionize in solution. Because they ionize at the same rate, and Calcium hydroxide has the higher pH calculated, then Calcium hydroxide, in fact, has the highest pH. Nitric acid is a strong acid, so it completely ionizes in water. Whilst nitrous acid is a weak acid. Therefore, the nitric acid solution has the LOWEST ph.

Answer: B) 37th Explanation: India has been ranked 37th out of 103 nations in the 2017 global Multi-dimensional Poverty Index (MPI), according to a new report by the Oxford Poverty & Human Development Initiative. The OPHI is an economic research centre at the Oxford University, led by Professor Sabina Alkire. The 2017 global MPI has covered 76% of the world’s population, living in 103 countries. The index measures the nature and intensity of poverty, based on the profile of overlapping deprivations each poor person experiences. It aggregates these into meaningful indexes that can be used to inform targeting and resource allocation and to design policies that tackle the interlinked dimensions of poverty together.

Answer: C) forest improving to deserts Explanation: Desertification is a type of land degradation in which a relatively dry area of land becomes increasingly arid, typically losing its bodies of water as well as vegetation and wildlife.   Conversion of a grassland or an already arid land into a desert through indiscriminate human actions magnified by droughts.   Hence, forest improving to deserts is refers to desertification.

Answer: B) Rocks Explanation: Lithoshpere are composed of rocks in the crust and upper mantle that behave as brittle solids. The lithosphere is Earth's outermost layer.
