Please answer SHOW WORK for ALL questions. 64. A50% efficient hydroelectric power plant generates electricity from water failing a height of kg/s. If the maximum possible power output of the plant was 27.0 110 m and at a rate of D) 5100 ka/s A) 25,00okgs ?) 50,000 kg C) 100,0oo kg/s Ans: B 45 AG 0%g block slides from point A down a frictionless ono to point B. After the block passes point B, a friction force opposes the motion...
can someone help me with this, someone else tried to help me but I didn't understand what they said 4. A 3 kg block is pulled up a rough incline by a rope that exerts a 25 N force that is parallel to the incline. The angle of the incline 0 = 30° and the coefficient of friction between the block and incline u = 0.2. The block is pulled 1 m along the incline the block starts from rest....
Work Done by the Govtational Force bute the gravitational force G m./r into the integral equation on the previous genith Y replacing and find the work done by this force df w is the work done by the gravitational for moves away from t he gravitational force positive, negative, or zero when an object in the Earth? When it moves toward the Earth? When it orbits the Earth in a circle? Part B: Conservative and Non-conservative Forces welop and understorence...
Which of the following statements are true? Because the Earth has mass it produces gravity. There is no gravity at the space station I need to do work to move a satellite from lower to higher orbit. Because the force of gravity is a conservative force and because it acts as a centripetal force it does no work, the mechanical energy of Earth is conserved and it will not crush into the Sun. Since Moon has no air, there is...
Is 1 correct? Can someone explain #2? QUESTION 1 Which of the following statements about conductive materials is incorrect? 1. Charges in a conductor move in response to an electric field. Examples of conductive materials include iron, aluminum, and gold. 3. Increasing the voltage applied across a conductor will cause the conductor temperature to increase 4 Current flow in a conductive material is due to the movement of positive and/or negative charges QUESTION2 Which of the following statements about voltage...
can someone show me how to do the work and explain it to me 12. Which of the following does not correctly describe NZ he following does not correctly describe SN2 reactions of alkyl halides? B. Tertiary halides react faster than secondary halides. e or reaction depends on the concentrations of both the alkyl halide and the nucleophie. The mechanism consists of a single step with no intermediates. The transition state species has a penta valent carbon atom.
Can someone please explain to me how is this less substituted? Please explain in detail. Thanks!! Remember, you're looking for the less substituted group, so "b" is correct.... 1) ВН, 2) Н,О, ОН- 3) Н,О b a CH3 CH3 он н н он less substituted, anti-markovnikov
Calculate the work WAB done by the electrostatic force on a particle of charge q as it moves from A to B. Express your answer in terms of some or all the variables E, q, L, and ?. Constants Learning Goal: To review the concept of conservative forces and to understand that electrostatic forces are, in fact, conservative. Calculate the work WAB done by the electrostatic force on a particle of charge q as it moves from A to B....
Can someone explain to me ? Thanks in advance! ooooo T-Mobile 9:04 PM T 46%, 13 Exit Suppose our new improved queue contains n elements that have been added to it. What is the best characterization of the big-O runtime to add one additional member to this queue? O(1) is synonymous with constant time. Assume that constructing a new InternalQueue object is a constant time operation. O(1) O(log n) O(n)
Sorry this problem has so many parts--thank you in advance for your effort. Conservative Forces It takes work to lift an object under the influence of the Earth's gravitational force. This increases the gravitational potential energy of the object. Lowering the ob- ject releases the gravitational potential energy that was stored when it was lifted. When you studied the gravitational force, you applied the term conservative to it because it allows the recovery of all of the stored energy. You...
