Answer : B. 0 m/s∧2
Now we know that velocity = distance/ time
And acceleration = velocity/time.
From the graph we see that at the time interval 2 secs,the distance travelled is 10 m. Hence the velocity(v1) =10/2 = 5m/s.
From the graph we see that at the time interval 5 secs,the distance travelled is 25 m. Hence the velocity (v2) =25/5 = 5m/s.
Now acceleceration between the time interval of 2 ad 5 secs is calculated as
(v1-v2)/t2-t1 = (5-5)/(5-2) = 0 m/s∧2
Answer:
Option 2. It cuts through all the other layers
Explanation:
Newer or younger rocks are usually formed from older rocks in the sense that older rocks are broken up, and their by product materials forming together to make younger rocks.
We can simply say that older rocks basically undergo recycling to form newer rocks.
Thus, looking at the given options,
For option 1, the newer rock cannot be crumpled while the others lie flat because it is the old one that is undergoing recycling and therefore the older one is the one that will be crumpled to give way for newer rocks. So it's not true.
For option 2, since they are from older rocks, they will clearly cut through the other layers of the old one because the old one will give way for the new one.
Option 3 is not true for the same reason given for option 1.
Option 4 is not true because there is no standard way in which it will be positioned
Answer:
This delay affect conversations in the sense that recipient will be receive the message just 2.56 seconds after the message was sent.
Explanation:
The laser pulse has an ondulatory nature as electromagnetic wave, which can travel in the void. Speed of light is constant and distance between Earth and the Moon is:
This delay affect conversations in the sense that recipient will be receive the message just 2.56 seconds after the message was sent.
Answer:
Vy = 26 m/s sin 30 = 13 m/s vertical speed
t = Vy / a = 13 m/s / 9.80 m/s^2 = 1.33 sec time to reach Vy = 0
H = Vy t + 1/2 g t^2
H = 13 m/s * 1.33 sec - 1.33^2 * 9.8 / 2 m = 8.62 m
