In Fig if F = 4N , m= 2 kg M = 4 kg then

From the following sets quantum number state which are possible. Explain why the other are not permitted ? a. n = 0, l = 0, m= 0, s = + 1//2 b. n = 1, l = 0, m= 0, s = - 1//2 c. n = 1, l = 1, m= 0, s = + 1//2 d. n = 1, l = 0, m= +1, s = + 1//2 e. n = 0, l = 1, m= -1, s = - 1//2 f. n = 2, l = 2, m= 0, s = - 1//2 g. n = 2, l = 1, m= 0, s = - 1//2

The expression ((cos A-cos B)/(sin A-sin B))^m+((sin A+sin B)/(cos A-cos B))^m where m in N has the value- a.2cot^m((A-B)/2), if m i s od d b. 0, if m i s od d c. 2cot^("m")((A-B)/2), if m i s e v e n d. 0, if m i s e v e n

The acceleration produced by a force of 5 N acting on a mass of 20 kg in m/ s^(2) is :

If a cos A+b sin A=m and a sin A-b cos A=n prove that a^(2)+b^(2)=m^(2)+n^(2)

lfcos A+s in B=m and s in A+cos B=n prove that 2sin(A+B)=m^(2)+n^(2)-2
