Different fabrics rub together, and electrons may rub off
Answer:
A hydrocarbon and oxygen
Explanation:
hydrocarbon is being burned, and oxygen is necessary to burn things
It would be false because you could hurt yourself while trying to get something I t he drawer
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)
Density=mass/volume so mass=density/volume mass=500ml/1.43g/ml mass=0.00286
