DETAILS PREVIOUS ANSWERS X J OSCOLPHYS2016ACC 7.3.P.016. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A hydroelectric power facility converts the gravitational potential energy of water behind a dam to electric energy. (For each answer, enter a number.) (a) What is the gravitational potential energy (in J) relative to the generators of a lake of volume 71.0 km³ (mass = 7.10 x 1013 kg), given that the lake has an average height of 35.0 m above the generators?
13. Say you have two protons which are 1m apart. The mass of a proton is, m_p = 1.67 * 10^-27 kg and charge is, q_p = 1.6 * 10^-19 C. Newton's constant, G_N = 6.67 * 10^-11 N m^2 kg^-2 and Coulomb constant, k = 8.987 * 10^9 N m^2 СЛ-2. Calculate this ratio: Gravitational force between the protons / Electrostatic force between the protons. What can you conclude from this?
Show and explain the complete solution with the formulas. Label the symbols used accordingly.
how would you solve this only using work/power formulas and PE/KE formulas?
Your discussion partner is confused about ideas discussed in Chapter that seem to contradict ideas discussed in this chapter. For example, in Chapter, we learned that the net force is zero for a car traveling along a level road at constant velocity, but in this chapter, we learned that work is done in such a case. Your discussion friend asks, “How can work be done when the net force equals zero?” Discuss your explanation.
What's the answer here? All of the above is wrong
3) The figure below illustrates a skier who is skiing on a large frictionless spherical ball of snow. The skier can be treated as a point-like object. The skier starts at the top of the ball with very little speed and picks up speed while traveling along the surface of the snow. During this time, the only forces acting on the skier are the gravitational force applied by the Earth and the normal force applied by the snow. At the moment the radial line extending from the skier to the center of the ball defines an angle a with respect to a vertical line, the skier is about to lose contact with the ball. Determine the value of a.
We know from the reading that it is possible to move the same object two different distances and still do the same amount of work. Let's consider an example in which Jane pushes a block of ice up an incline while Kip lift the same block of ice vertically to the top of the same incline. See the figure below. (look at picture) We will assume that there is no friction between the surface of the incline and the block of ice. Both of these situations will require the same amount of work and that the result of lifting the ice block to some height imparts potential energy to the ice. In this activity, we will make various calculation to help us better understand the relationship between work and potential energy and the idea of conservation of energy. For this activity we will assume that the mass of the ice block is 5.6 kg and the vertical height of the incline is 2 m. This is the vertical distance that Kip must lift the block of ice. We will assume that the acceleration due to gravity is 10…
A 20m rope is hanging over the edge of a 50m building. Attached to the end is 2 kg bucket carrying 30kg of sand. There is a whole in the bucket that allows the sand to leak out at 0.5 kg/m. Disregarding the rope, how much work is done lifting the bucket to the top of the building? Show all work. Include units. Method of solving: fnint(), rounded to nearest whole number or Fundamental Theorem. Your choice
A hiker of mass 73 kg is going to climb to the top of Mount Tam, which has an elevation of 2,574 ft. a) If the hiker starts climbing at an elevation of 545 ft, what will their change in gravitational potential energy be, in joules, once they reach the top? Assume the zero of gravitational potential energy is at sea level. b) Repeat the above calculation for the change in gravitational potential energy, but assume the gravitational potential is zero at the top of the mountain.
