<span>During their embryonic stage they have a flexible cord that supports their bodies which disappears in the adult stage. Some of these develop bones surrounding the cord in the adult stage rather than have it disappear.</span>
The question doesn't describe any experiment. If the same experiment is repeated, no matter how many times, the acceleration due to gravity will remain the same as it was during the non-existent original experiment, and will have no effect on anything.
In both graphs, speed will be measured in meters/second.
In graph A, the object travelled a distance of 40 meters in 4 seconds
In graph B, the object is at rest for 5 seconds.
These are the correct answers
Answer:
omg halloween lol hows karma, you wasted my points and a chance for others to answer!! :)))
Explanation:
Answer:
18.896ms-1
Explanation:
The tangential acceleration of the car= 0.747ms-2
The centripetal acceleration is given by v^2/r
0.747= v^2/r
V= √0.747*478= 18.896ms-1
