3. A student living in a 4-m X 6-m X 6-m dormitory room turns on her 150-W fan before she leaves the room on a summer day, hoping that the room will be cooler when she comes back in the evening. Assuming all the doors and win- dows are tightly closed and disregarding any heat trans- fer through the walls and the windows, determine the tem- perature in the room when she comes back 10 h later. Use specific heat...
1. A 67.0 kg football player is gliding across very smooth ice at 2.10 m/s . He throws a 0.460 kg football straight forward. Part A: What is the player's speed afterward if the ball is thrown at 14.0 m/s relative to the ground? Express your answer with the appropriate units. Part B: What is the player's speed afterward if the ball is thrown at 14.0 m/s relative to the player? Express your answer with the appropriate units. 2.A ceiling...
please solve this on paper wiyh the steps thank u Q.1) A mole of X reacts at a constant pressure of 43.0 atm via the reaction: X(g) + 4Y(g) + 2/(g) AH° = -75.0 kJ Before the reaction, the volume of the gaseous mixture was 5.00 L. After the reaction, the volume was 2.00 L. Calculate the value of the total energy change, AE, in kilojoule. Show your work, express your answer to three significant figures, and include the appropriate...
Resistors in Series and Parallel 1 of 9 RAVAW Constanta Learning Goal: To find the equivalent resistance of resistors that are in series andior paralel For many electrical circuits their anles can be simplified by Inding the equivalent res stances for resistors that are in series and/or paralel - Part A. Calculation of the equivalent resistance for resistors in series For the circuit shown in Figure 1), what is the equivalent resistance between the terminals A and B when R....
