The displacement function is given by : r = bt2i + ct3j meters
The velocity function is the derivative of the displacement:
v = r' = 2bti + 3ct2j meter / second
Now, for <span> the velocity vector make an angle of 45.0∘ with the x- and y-axes, the i and j components have to be equal:
</span>2bt = 3ct2 (Now solve for t)
2bt = t (3ct)
either t = zero (rejected)
or t = 2b / 3c seconds (accepted)
Answer:
0.000435
Explanation:
Because it is 10-4, you move the decimal place to the left four times. this will result in 0.000435.

Answer:
Mass of arsenic chloride produced is 0.363 g
Explanation:
Given data:
Mass of arsenic chloride produced = ?
Mass of arsenic react = 0.150 g
Mass of chlorine = excess
Solution:
Chemical equation:
2As + 3Cl₂ → 2AsCl₃
First of all we will calculate the number of moles of arsenic.
Number of moles = mass/ molar mass
Number of moles = 0.150 g/ 75 g/mol
Number of moles = 0.002 mol
Now we will compare the moles of arsenic with arsenic chloride.
As : AsCl₃
2 : 2
0.002 : 0.002
Mass of arsenic chloride produced:
Mass = number of moles × molar mass
Mass = 0.002 × 181.28 g/mol
Mass = 0.363 g
