C because it’s not a or B so 50/50 c or d and d is def not the answer so c
Acceleration = (velocity final-velocity initial)/ time
where
velocity final = 135 km/hr x 1 hr /3600 s x 1000m/1km
= 37.5 m/s
velocity initial = 35 km/hr x 1hr /3600 s x 1000 m/1 km
= 9.72 m/s
a) acceleration = 2.646 m/s^2
b) acceleration in g units = (2.646m/s^2)/(9.8m/s^2)
= 0.27 units
Answer:
<em>1. c. Same in both</em>
<em>2. a. Case 1</em>
<em></em>
Explanation:
1. The balls are identical in all sense, which means that if they are dropped from the same height, they should posses the same kinetic energy just before they collide with either the concrete floor or the stretchy rubber. Also, since they reach the same height when they bounced of the concrete floor or the piece of stretchy rubber, it means that they posses the same amount of kinetic energy at this point. Since their kinetic energy at these two points are the same, and they have the same masses, then this means that their momenta at these two instances will also be equal. Since all these is true, then the change in the momentum of the balls between the instance just before hitting the concrete floor or the stretchy rubber material and the instant the ball just leave the floor or the stretchy material is the same for both.
2. The ball that falls on the concrete will experience the greatest force, since the time of impact is small, when compared to the time spent by the other ball in contact with the stretchy rubber material; which will stretch, thereby extending the time spent in contact between them.
Expectations relate to future schooling by choosing classes that are at your skill level.
Answer: Option B
<u>Explanation:
</u>
Each individual has a different set of skills blessed by the Mighty and each should enhance them according to his/her will and interest. For the future prospects of schooling and teaching, there is one noticeable point to be acted is that students should not be forced to study the subject beyond their skills and capability.
We should remember that a fish cannot fly and a bird cannot swim. They both cannot be trained under the same study programmes. Although they both can know how to swim and fly but it’s their capability and interest over the subjects that can lead them further to rule over either the sky or the oceans.
So, the future school programming should be done in such a way that individuals have an authority to choose their subjects accordingly and learn more about their skills.
The constellation is the dependent variable because they depend on the stars to form them.
Stars are independent variables in this case because they do not need constellations to form them.
Constellations are dependent variables in this case because they depend on stars to form them. Constellations are literally a group of stars that make an imaginary picture to us.
