A pendulum is an example of an oscillator where we can watch ... electric charge accumulate on capacitor plates. liquid water boil into steam. its energy periodically change forms between kinetic and potential.

the potential energy of a particle is given by U(x)= (9 J/m^4)x^4-(8 J/m^2)x^2.  At what value of x would the particle be in unstable equilibrium? A.) -2/3 m B.) sqrt of 8/9 m c.) 0 m d.) 2/3 m e.) sqrt of - 8/9 m

Question: Three identical 5.6 kg spheres are located at 3 of the 4 corners (top left, top right, and bottom right) of a square whose sides are 2.8 m in length. How much work must be done on the gravitational field produced by the spheres in order to remove the top right sphere (place it at infinity)? Assume that the 2 spheres that are left behind (top left, bottom right) remain located on opposite corners of the square. A) 1.50 x 10-9 J B) 5.34 x 10-10 J C) 1.89 x 10-10 J D) 2.67 x 10-10 J E) 5.29 x 10-10 J OA E B. C.

Q19 The concept of escape velocity can be best described as: (A) The initial speed required so that an object will safely orbit the Earth. (B) The speed for an object to be launcned and fly through space forever. (C) The speed necessary for a spacecraft to escape Earth's atmosphere. (D) The velocity needed to provide an initial kinetic energy such that total mechanical energy is zero.

2. For a satellite in a circular orbit around the earth, the gravitational force from the earth on the satellite causes the centripetal acceleration. The amount of work done by the gravitational force from the earth on the satelliteA) is zeroB) is greater than zero.C) is less than zero.D) would be different if the masses of the earth and satellite were different.E) can’t be determined without a calculator and some data.i. Prove your answer by using the formula for work, W: (Hint: Consider just a short segment of the orbit, rather than the full revolution.) ii. Prove your answer by talking about the satellite’s kinetic energy, ∆?� ***also please do it i,ii and write a process detail.
