They always see the glass as half full than half empty because they are always trying to find the light in the dark , they will always act towards success even when it is impossible to do so.
Answer:
increase the tilt of the yellow track
Explanation:
Based on the information provided within the question it can be said that the best way to potentially allow the yellow track to win would be to increase the tilt of the yellow track. Increasing the tilt and making the track more steep would allow gravity to apply more force and less resistance will push up from the track, thus allowing the ball to travel at a faster speed.
Answer:
3. Over-driving
Explanation:
A driver is said to be overdriving headlights when the driver is driving the vehicle so fast that the stopping distance is farther than than the distance which is visible to the driver with the headlights of the vehicle.
This can be dangerous as the driver might not give himself the enough room to apply the brake and make a safe stop.
Also, the reflective road signs boards can mislead.
Answer:
having half the swimmers first swim without fins and then with fins and having the other half swim first with fins and then without fins.
Explanation:
counterbalanced repeated measures is methodology of experimentation in which sample for experiment is divided into two parts equally. The first follows the condition of experiment in one series of step while other part follows the steps precisely opposite to that of first part. The objective of such methodology is to cover each condition of experimentation and nullify any error condition for every sample. It also makes sure that in series of steps, sequence does not affect the result.
Since in the above experiment Powel wants to counterbalancing first he needs to divide the sample of swimmer into two parts. Then both parts should follows opposite steps.
This can be best followed by
in first half sample
- test the speed of swimmer without fins
- then test the speed same set of swimmer without fin
- then see the discrepancy in the speed
second half sample
- test the speed of simmers with fins
- test their speed without fins.
- see the discrepancy in the speed
then compare the results of both set of sample. It will make sure that both half corroborate the same result, also sequence of with and without fins does not effect the result and produce biased result.
based on this option 3 is correct answer.
Mesopotamia belonged to a region located in the Middle East (predominantly in present-day Iraq) between two major rivers: the Tigris and the Euphrates. Their natural conditions, mainly because of soil fertility, allowed small villages to be formed on their territory.
Soil fertility was ensured by the flooding cycle of the two rivers that soaked the soil with organic material and allowed the development of agriculture and animal husbandry. The word "Mesopotamia" originates from the Greek language and means "land between rivers" in a direct mention of the importance of rivers for that region.
