A machine part rotates at an angular speed of 0.07 rad/s; its speed is then increased to 3.4 rad/s at an angular acceleration of

34kurt

Answer:

In first case angular displacement will be 11.55 radian

In second case it will be 4 times the previous case

Explanation:

We have given that machine rotates at an angular velocity of 0.07 rad/sec

So initial angular velocity $\omega _i=0.07rad/sec$

And its speed is increases to 3.4 rad/sec

So final angular velocity is $\omega _f=3.4rad/sec$

Angular acceleration $\alpha =0.5rad/sec^2$

According to third equation of motion we know that

$\omega _f^2=\omega _i^2+2\alpha \Theta$

$3.4^2=0.07^2+2\times 0.5\times \Theta$

$\Theta =11.55radian$

Now initial angular velocity and final angular velocity both are doubled but angular acceleration is constant

So $\omega _i=2\times 0.07=0.14rad/sec$

And $\omega _f=2\times 3.4=6.8rad/sec$

So $6.8^2=0.14^2+2\times 0.5\times \Theta$

$\Theta =46.22radian$

So angular displacement will be 4 times the earlier displacement

If Vector A is (3, 0) and Vector B is (-3, 3), what is the resultant?

Archy [21]

Answer:resultant vector R = (0, 3)

Explanation: vector A = (3, 0)

vector B =(-3, 3)

Vectors are added such that those in same directions are added together. The resultant vector R is the given by R = (3-3, 0+3)

= (0, 3)

You are looking at a yellow flower growing outside in the sunshine. Why does it look yellow?

Alchen [17]

Answer:

It looks yellow because that is the only (major) color reflected.

Visible spectra is from about 4000-7000 Angstroms (10^-10 m).

Red are longer wavelengths and blue are the shorter wavelengths.

The Sodium doublet (yellow) occurs around 5900 Angstroms.
