True, according to the Kinetic Molecular Theory.
Answer: 60
Explanation: if u hit it it will have impact and the impact added 10n
Explanation:
1. Rt = 30/(1+3+6) = 30/10= 3 ohm
i = V/Rt = 15/3 = 5 A
2. Rt = 3+1+ (12×6)/(12+6)
= 4 + (72/18)
= 4+4 = 8 ohm
i = 12/(8+2)
= 12/10 = 1,2 A
Answer:
Diffraction equation applies in this case:
d*Sin x = m*wavelength, where d = spacing of lines, x = angle = 39.5°, m = order of maximum = 2
Substituting;
d* Sin 39.5 = 2*600*10^-9
d = (2*600*10^-9)/Sin 39.5 = 1.88656*10^-6 m
In 1 mm (or 0.001 m), the number of lines is given as;
Number of lines = 0.001/d = 0.001/(1.88656*10^-6) = 530.065 ≈ 530 lines

I hope this is of help to you, and happy studying~!
