In a rotating body `a=alphar and v=omegar`. Thus `a/alpha=v/omega`. Can you use the theorems of ratio and proportion studied in algebra so as to write
`(a+alpha)/(a-alpha)=(v+omega)/(v-omega)`

Write difinition of wave speed and derive v = (omega )/(k).

If alpha particle and deutron move with velocity v and 2v respectively, the ratio of their de - Broglie wave length will be________.

The linear velocity of a rotating body is given by vec(v)=vec(omega)xxvec(r) , where vec(omega) is the angular velocity and vec(r) is the radius vector. The angular velocity of a body is vec(omega)=hat(i)-2hat(j)+2hat(k) and the radius vector vec(r)=4hat(j)-3hat(k) , then |vec(v)| is-

Write relation between alpha_(l),alpha_(A) and alpha_(V) .

Draw graph of alpha_(V)to temperature.

alpha -particle and deuteron moves with speed v and 2v respectively .What will be ratio of de-Broglie wavelength ?

In the figure, a vectors x satisfies the equation x-w=v. then, x is equal to
