Answer:
1. heat engine ~~ •a machine that converts the internal energy of a fuel into mechanical energy.
2. heat pump ~~ •an appliance that extracts heat energy from one source and deposits it
elsewhere.
3. Boiler ~~ •a heating appliance that uses heat energy released from fossil fuels to warm water for use in radiant or
convection heating systems.
4. Thermostat ~~ •an appliance that controls the maintenance temperature of a heating
system
The correct answer is their difference in the charge to mass ratio a mass spectrometer, a compound is first vaporized and converted into ions .
Mass spectrometry is a technique for determining the mass-to-charge ratio (m/z) of one or more molecules in a sample. These measurements are frequently used to calculate the precise molecular weight of the sample components.
The speed at which positively charged ions move through a vacuum chamber toward a negatively charged plate is measured by mass spectrometers. ToF, magnetic sector, and quadrupole mass spectrometers are all commonly used in SIMS instrumentation.The MS/MS has three major advantages: the ability to study numerous molecules regardless of whether they are from the same structural family or not; the ability to highlight the specific metabolites of a disease; and it is an automated technique that allows for large-scale analysis.

Answer:
1. B
2. C
3. B
4. A
5. D
Explanation:
The set of scenarios in this question depicts the NEWTONS THIRD LAW OF MOTION, which states that when an object 1 exerts an action force on an object 2, the object 2 exerts a reaction force that is opposite but equal in magnitude on object 1.
- In question 1, a ball (object 1) bounces on the ground (object 2). According to Newton in his third law, the ball and the ground exert forces on each other with equal magnitude but in opposite directions.
- In question 2, according to Newton third law of motion described above, If two moving objects collide, then they will move away from each other in opposite directions.
- In question 3, if two metal balls with the same mass hang so that they are touching each other. When the ball on the left is pulled to the side and released, it swings back and hits the ball on the right causing the ball on the right to move to the right while that on the left to move left (opposite directions).
- In question 4, bumper cars at an amusement park demonstrate third law of Newton in such a way that if two bumper cars collide with a certain force, then they will move away from each other in opposite directions with the same force.
- In question 5, when the octopus ejects the water out, the water acts with an equal force on the octopus in the opposite direction causing the octopus to propel itself through the water. This demonstrates Newton third law of motion.
Answer:
Explanation:
Average speed = Total distance / Total time.
100 km/hr
r = 100 km / hr
t = 6 hours
d = 6 * 100 = 600 km
120 km / hr
r = 120 km / hr
t = 5 hour
d = 120 * 5
d = 600 km
Total distance = 600 + 600 = 1200 km
Total time = 5 hour + 6 hours = 11 hours.
Average speed = 1200 km / 11 hours = 109.1
