Speed = distance/time taken
1484 = distance/3
Distance = 1484 x 3
Distance = 4452 m
Answer:
The average speed during the trip is 6.16 
Explanation:
Speed is a physical quantity that expresses the variation in position of an object and as a function of time. In other words, speed expresses the relationship between the space traveled by an object, the time used for it and its direction.
The speed can be calculated by the expression:
Aaron rode his bike home for 1.6 hours at 6.5 km/h and another 15 minutes at 4 km/h. So, the distance in each of the stages can be calculated as, taking into account that 60 minutes= 1 hour:
- distance1=speed*time= 6.5
*1.6 hours= 10.4 km
- distance2= speed*time= 4 *15 minutes= 4 *0.25 hours= 1 km
So:
- total distance= 10.4 km + 1 km= 11.4 km
- total time= 1.6 hours + 0.25 hours= 1.85 hours
Then:
<u><em>The average speed during the trip is 6.16 </em></u><u><em></em></u>
False. Energy in any form is a scalar quantity.
Nebular hypothesis.
Explanation:
- The first version of the nebula hypothesis was proposed by Immanuel Kant and Pierre Laplace.
- Today the hypothesis has been revised to fit into more current and update realities about how our solar system emerged.
- The hypothesis is the widely accepted explanation to the origin and evolution of the solar system.
- It suggests that the star and the planets that makes up the solar system were products of a huge cloud of dust called the nebular.
- The nebular is a huge mass of interstellar dusts.
- The cloud collapsed and condensed under gravitational pull of the materials.
- A center core that resulted in the formation of our star, sun emerged and the rest of the particles formed our planet.
