A girl travels 50 m East in 10-minutes and later 100m north in 15 minutes. what is her total displacement?​

a girl travel 50 metre is used in 10 minutes and letter hundred not in 15 minutes what is the total

Explanation:

displacement displacement is like a 5+ x + 15 is equals to what so so you plus them all and you will get your answer

111.80 meters

Explanation:

Displacement = A^2 + B^2

50^2 + 100^2 = 12 500 (route the answer )

S= 111.80 meters

newton's first law of motion

  the grams     of oxygen gas   that can be produced     is 20.6   grams of o₂

calculation

2liclo₃ →   2 licl + 3 o₂

step 1:   find the moles of liclo₃

moles = mass÷ molar mass

from periodic table the molar mass of liclo₃ =6.9 +35.5   +(16 x3) =90.4 g/mol

moles=38.7 g÷90.4 g/mol=0.4281   moles

step 2:   use the   mole ratio   to calculate the moles of o2

from equation above, liclo₃: o₂   is 2: 3  

therefore the moles of   o₂=0.4281 moles x3/2 =0.6422   moles

step 3: find mass   of o₂

mass= moles x molar mass

from periodic table the   molar mass of   o₂ = 16 x2= 32 g/mol

mass=0.6422   moles   x   32 g/mol = 20.6 grams of o₂
