Answer:
<u>Initial</u><u> </u><u>speed</u><u> </u><u>is</u><u> </u><u>3</u><u>2</u><u> </u><u>m</u><u>/</u><u>s</u>
At uniform speed, acceleration is 0, (a = 0).
When speed reduced, (v - u) = 2.78 ms-¹, t = 1800 sec, s = 60 ,000 metres.
From first equation of motion:
substitute:
from second equation of motion:
55.5
Step-by-step explanation:
Answer:2/3
Answer
The reaction 2 Fe + 3 H₂SO₄ -> Fe₂(SO4)₃ + 3 H₂ has the same coefficients in the same order as 2 CO₂ + 3 H₂O -> C₂H₆O + 3 O₂
6*7=42
