(d) kg g (e) 1000 g * 500 g (0) 1000 g = * 200 g (9) 1000 g = x 250 g (h) 1000 g = x 100 g (i) 1 kg x 50 g 0 kg g What are the different ways in which you can measure 2 kg of mangoes. 500 g 100 g 50 g = 3. 250 g 200 g (a) Using only 500 g (b) Using only 250 g 2 kg (c) Using only 250 g and 200 g (d) Using only 250 and 100 g (e) Using 500 g, 250 and 50g 110​

Answer 1

Step-by-step explanation:

Potential energy =m×g×h (here m=200kg, g=9.8ms−2, potential energy =9800 joule)

9800J=200Kg×9.8ms−2×h

h=200×9.89800

h=5m

Thus, the bag of wheat should be raised to a height of 5m.
