Story of Newton's Laws of motion: Once a cow was walking Newton stopped it..........it stopped! He found his First Law:"An object continues to move until it is stopped...!" Then he gave a Force "F" by kicking the cow... Cow gave a sound..."ma" He formulated the second law: "F=ma"...- salvatore

The man's motion is a projectile; hence, the horizontal component is always constant and the vertical component is the one that changes. This means that velocity can never be zero since there is a non-zero horizontal component that never changes. So C is ruled out! A can not be the answer... -

For open-ended tubes: One full loop is always formed The number of loops can be changed using the frequency.. Yeah, the loops will be half, one and a half etc.. and 1/4lambda, 3/4lambda, 5/4lambda respectively. I'm not very sure of f = V/4L, but I usually count the number of loops, and add the... -

Chemistry and Physics AS paper 12 MCQS
(16) You know that the weight always acts at the centre.. so lets assume the distance XY to be 1m. The horizontal component of force F is Fsin30. Sum of clockwise moments = sum of anti-clockwise moments 0.5 x 10 = 1 x Fsin30 F = 10N (17) The tension (4N) is the same on both sides; XY and XZ... -
