- Find the volume of a balloon of gas at 842 mm Hg and -23^circ C if its volume is 915 mL at a pressure of 1170 mm Hg and a te of 24^circ C (P_(1)V_(1))/(T_(1))=(P_(2)V_(2))/(T_(2)) "convert those temperatures" 9.34mL 1070mL 12140mL
- 15. Normal force is defined as resistance of an object to a change in its velocity. rate at which velocity changes force exerted by a surface that opposes motion as an object moves across it. force exerted by a surface to support the weight of an object.
- A gas occupies 100mL at a pressure of 789mm Hg. What is the volume of the gas when it's pressure is increased to 880mm Hg P_(1)V_(1)=P_(2)V_(2) 113mL 190mL 89mL
- ANSWER THE FOLLOWING QUESTIONS IN YOUR COMPOSITION BOOK SUBMIT PHOTO OF YOUR WORK ON CANVAS. Understanding Work, Kinetic Energy, Potential Energy, and Conservation of Mechanical Energy In physics, understanding the concepts of work, kinetic energy (KE), potential energy (PE), and the conservation of mechanical energy is fundamental. Work is done when a force causes an object to move. Kinetic energy is the energy an object possesses due to its motion, while potential energy is stored energy based on an object's position or state The principle of conservation of mechanical energy states that in a closed system, the total mechanical energy (sum of KE and PE) remains constant, provided no external forces like friction act on it. Fill in the Blank:Fill in the blank with the correct words. 1. When an object is lifted, its __ energy increases 2. The __ of an object in motion is called kinetic energy 3. Work is equal to the force applied multiplied by the __ over which it is applied. 4. The law of conservation of mechanical energy states that the total __ of a system remains constant if no external forces are applied 5. The energy stored in an object due to its position in a gravitational field is known as __ energy Word bank in English potential, distance, mechanical energy, kinetic, potential Multiple Choice Questions Choose the correct answer from the choices for each
- The density of an object is equal to its mass divided by its volume. If a rock sample has a mass of 360 grams and a volume of 120 cubic centimeters, what is the density of the sample in grams per cubic centimeter? Choose 1 answer: A A 3 B 240 C 480 D 1.080
