The velocity is 1100 kilometers per hour
an independent variable (IV) that you can change. • Typical IV's might be number of fins, length of rocket, type of material, mass of the rocket. • Choose one dependent variable (DV) and make three launches per DV for each IV for a total of. six launches..
Explanation:
I. Positive acceleration increases velocity. Negative acceleration decreases velocity. runner A sped up until the finish line and then slowed to a stop.
ii. Zero a acceleration implies a constant, unchanging velocity not a zero velocity. runner B achieved some velocity prior to 8s and is moving and must slow down to reach a stop.
iii. None. No aspects of this reasoning are correct. Everything she says is wrong. See iv for what/why.
iv. The sign on acceleration denotes the direction of *change in velocity* not change in direction. The sign on velocity can denote change in direction but only “forward” or “reverse” along a particular path. Cardinal direction is not indicated, generally, by the sign on velocity. It may correspond to North/South situationally but it is not an built-in feature of velocity and its sign. For example, if you are traveling with positive velocity and turn left to continue your journey you still have a positive velocity in the new direction. In fact, if you turn left again, traveling in the opposite direction as the one you started with your velocity would still be positive… in the new direction. The velocity relative to original direction could be said to be negative but that would be a confusing way to describe a journey. Maybe if you stopped the vehicle and moved in reverse, you could meaningfully say velocity was negative.
<u>Answer:</u>
The statement is true statement
<u>Explanation:</u>
Tropical rainforests are dry and green throughout the year. Even between the day and the night, temperatures don't change much. in tropical rainforests The average temperature varies from 70 to 85 °F (21 to 30 °C) .
Throughout tropical rainforests, the climate is quite wet, maintaining a humidity level of 77% to 88% year around which is a high value. The annual rainfall is between 80 and 400 inches (200 and 1000 cm), that is 6-33 feets, and it can rain heavily. It can drain as much as 5 cm (2 inches) in an hour.
