I believe the answer is:
random sample of the town's population
A mix of participants that reflect your town's makeup
Random sample is needed in order to ensure that the researchers do not obtain only the subjects that is close to them. Mix of participants is needed in order to ensure that the sample population are not taken from group with close similarties in behaviour.
Answer:
The correct answer is c. There is no component of force acting along the direction of motion of the satellite.
Explanation:
When a moving object is traveling in a circular orbit at a constant speed we assume it has a changing velocity, this is mainly because velocity is a vector quantity that rely on the speed the object is moving and direction, because of the variation of acceleration throughout the whole orbit and the lack of other force acting along the direction of motion of the satellite allows the object to travel at a constant speed, but variable acceleration.
i believe the answer is: Fuel filter
Fuel filter is a part of your vehicles that screens out various form of small particles from the fuel (such as dirts). Every 15,000 miles, there would be a chance that your fuel filter is clogged. If this fuel filter is not changed, it would be hard for you to start your car.
