Q1. A 44.0 kg child is in a swing that is attached to ropes 1.60 m long. The acceleration of gravity is 9.81 m/s2. Find the gravitational potential energy associated with the child relative to the child's lowest position under the following conditions:
a) when the ropes are horizontal.b) When the ropes make a 32.0? angle with the vertical.c) At the bottom of the circular arc.
Q2. A syringe with a plunger of diameter 2 cm is attached to a hypodermic needle with a diameter of 2.4 mm. What minimum force (in N) should be applied to the plunger to inject into a vein where the pressure is 18 torr above atmospheric pressure?

A loudspeaker is placed between two observers who are 120 m apart, along line connecting them. If one observer records a sound level of 52.8 dB and the other records a sound level of 83.5 dB, how far is the speaker from each observer? Enter the longe..
Use this technique to find formula for the intensity of a sound, in terms of sound level and the reference intensity. There will be a quantity involved in the calculations. When you enter your answer, leave off the unit.
Three pendulums with strings of the same length and bobs of the same mass are pulled out to angles q1, q2 and q3 correspondingly and released. The approximation sin q = q holds for all three angles, with q3 > q2 > q1. How do angular frequencies of th..
