Homework Statement
Suppose that a dietitian has 3 groups of foods, having 5 items in the first group, 7 items in the second group and 2 items in the third group.
1. How many meals are possible containing one food from each food group?
2. How many meals are possible containing 3 foods from...
A 5.00 g bullet moving with an initial speed of v0 = 405 m/s is fired into and passes through a 1.00 kg block, as in Figure P13.58. The block, initially at rest on a frictionless horizontal surface, is connected to a spring with a spring constant of 950 N/m.
Figure P13.58
(a) If the block...
can someone answer this please
does the period have any m dependence in the simple pendulum? No right since its a masless rod. Also under what condition does the theoretical formula hold for the simple pendulum, would it be only for larger angles and amplitudes?
Also there is a mass dependence...
thanks alot, also does the period have any m dependence in the simple pendulum? No right since its a masless rod. Also under what condition does the theoretical formula hold for the simple pendulum, would it be only for larger angles and amplitudes?

What is the similarity between Simple Harmonic Oscillation(SHO), simple pendulum and a physical pendulum? I never understood it. Like whats the physical significance of SHO, or the energy and momentum change in oscillating motion?
^ I have it written on top but if u want it again
((1.013X10^5 Pascals)(.004m^3))/20 Celsius= (((1.013X10^5 Pascals + 2X10^3N/m X height)/0.0100 meters^2)(.004m^3 + 0.0100meters^2 X height))/all over 230 Celsius
L= 270
change in L/270= 12 X 10^-6 (21)= 0.06804
270+0.06804= 270.06804
270/2= 135
270.06804/2= 135.03402
now according to u I should do pythagorean theorum, which I did and got 190.9
thats not right
I got it though finally, when I do L/2, which is 270/2= 135, take the change in L, which is...
