A diver on a diving board is undergoing simple harmonic motion. Her mass is 46.0 kg and the period of her motion is 0.950 s. The next diver is a male whose period of simple harmonic oscillation is 1.15 s. What is his mass (in kg) if the mass of the board is negligible?
Question 13 1 pts If the length of a pendulum from its support to the center of the bob is held constant but the amplitude of the motion is decreased (but still small) the period of the pendulum increases stays the same decreases may increase or decrease Question 14 1 pts If the mass of a pendulum bob is held constant but the length of the string holding it is decreased the period of the pendulum increases stays the same...

Show all work. Use units. Take g = 10 m/s2. 10 pts per question except as noted. Use 3 sig figs for all calculations. Ignore air resistance A 55 kg person stands on a scale holding a 2 kg mass. Assume the scale responds instantly to changes in forces pushing on it. The person now throws the 2 kg mass straight up with a throw that lasts 0.150 s. After the 2 kg mass leaves the thrower’s end, it makes...
Question 2) This diagram shows a mass of 0.500[kg] that can move along the x-direction. An ideal spring also along the x-direction is attached to the mass and the wall. But it could be a different spring than the one in question #1 The spring is relaxed when the mass is located at the equilibrium position which is at, x-0001ml. Assume that the force by the spring is the only force acting on the mass During the oscillations, the location...
D Question 16 1 pts How does the University of Rochester "revisited" marshmallow task study we discussed in class inform our understanding of how self-regulation develops? If an individual is raised in an environment where rewards are not guaranteed, they may learn to delay rewards until their other responsibilities are met (i.e. they will have better self-regulation). If an individual is raised in an environment where rewards are plentiful, they may learn they never need to delay gratification (i.e. they...

QUESTION 1 239 a) (15 p) We consider a nuclear reactor of power output P-1000 Megawott (1000 million watts) electric functioning with Plutonium. It is fueled, initially, with 1000 kg of Plutonium. The nuclear material in question is made of Plutonium nuclei, each consisting in 94 protons and 239-94-145 neutrons, which is rd denominated by the symbol 94 Pu For thermodynamical reasons, only 1/3 of the nuclear energy in the form of heat produced by the reactor, can...

please help! this is a fluids question in physics.
1-3 (a) What is the height of a fluid column in a barometer that uses water as its 5 pts fluid in 0.924 atm of air pressure? The density of water is 1000 kg/m'. Neglect the vapor pressure in the apparently empty space above the column. Use g = 9.80 m/s² and give the height in meters. m( + 0.02 m) (b) What is the height if the fluid is mercury?...
