Answer:
this doesnt make sence ezxplain the subject
Explanation:
In a perfect world without air resistance, the top of the swing would have the most potential energy, but the least amount of kinetic energy. As the pendulum falls down, it gains more kinetic energy as it travels faster due to gravitational acceleration but loses more potential energy as it loses height. The total amount of energy in the system (the sum of kinetic and potential energy) stays the same.
The answer would be W and Z
Answer:
B- Lower temperature causes a reduction in movement
Explanation:
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space
Answer:
455 Torr
Explanation:
To get the correct answer, we employ the use of the General gas equation.
In its general form, the General gas equation can be written as:
P1V1/T1 = P2V2/T2
Defining the parameters;
P1 = 764 torr
V1 = 8.6L
T1 = 45 degrees Celsius = 273.15+ 45 = 318.15K
P2 = ?
V2 = 13.3L
T2 = 20 degrees Celsius = 273.15 + 20 = 293.15K
Rearranging the equation yields: P2 = P1V1T2/T1V2
Substituting the values:
P2 = (764 * 8.6 * 293.15)/(318.15 * 13.3)
P2= 455.2 Torr
