An object has a mass of 12 kg. On Planet A, the object weighs
69 N. The force of gravity on Planet A is can be solve using the formula F=mg
where F is the weight, m is mass and g is the force of gravity:
g = F/m
g = 69 N/ 12 kg
g = 5.72 m/s2
Agar woh thoda size mei bada ho to aa raha hai aur door jaata hai to gayab ho jata hai aur chamakta hai.
400ml has 15% alcohol i.e 60ml . means we have 340ml of water or the liquid with alcohol is mixed let v be the volume of alcohol added to make the strength 32% then v/340+v = 32/100. solving we get v as 160ml
