Answer:

Reagent: aqueous bromine

Observation with ethene: solution turns from brown to colourless.

Observation with ethane: solution remains brown

Explanation:

Unsaturated compound contain C - C double bond while Saturated compound contain C - C single bond. Alkenes with C - C double bonds (unsaturated) can undergo bromination reaction while alkanes (saturated) are not able to do so due to the absence of C - C double bonds.

A mass attached to the end of a spring is oscillating with a period of 2.25 s on a horizontal frictionless surface. The mass was
Rudiy27

Answer:

X=0.0389m

Explanation:

From the question we are told that:

Period of spring T_s=2.25s

Initial Position of Mass x=0.0480m

Final Mass period T_f=5.85s

Generally the equation for the Mass location is mathematically given by

X=xcos*\frac{2\pi T_s}{T_f}

X=0.048*cos*\frac{2\pi 5.85}{2.25}

X=0.0389m

A uniform disk with a mass of 5.0 kg and diameter 30 cm rotates on a frictionless fixed axis through its center and perpendicula
Marina86 [1]

Answer:\alpha =10.66 rad/s^2

Explanation:

Given

mass of disk m=5 kg

diameter of disc d=30 cm

Force applied F=4 N

Now this force will Produce  a  torque of magnitude

T=F\cdot r

T=4\dot 0.15

T=0.6 N-m

And Torque is given Product of moment of inertia and angular acceleration (\alpha )

T=I\cdot \alpha

Moment of inertia for Disc I= \frac{Mr^2}{2}

I=0.05625 kg-m^2

0.6=0.05625\cdot \alpha

\alpha =10.66 rad/s^2
