Answer:
Less than a quarter of Earth's surfaces are dry, ice free lands
Answer:
a) speed when Jack sees the pot : 12.92 meters per second
b) height difference 163.115 meters
Explanation:
First to calculate te initial speed we use the acceleration formula:
a= v1-v0/t
Acceleration being gravity's acceleration (9.8 m/s^2)
v1 being the speed when Jill sees the pot
v0 when Jack sees it
and t the time between
Solving for v0 it would be
v1 - a*t = v0
replacing
For the second question we use the position formula setting y0 and t0 as the position and time when jack sees the pot. (and setting the positive axis downward I.E. one meter below jack would be 1m not -1m)
The formula is
replacing
There won't be another period where many brilliant discoveries are made in such a span of time because of the high degree of advancement already.
<h3>What is Technology?</h3>
Tgis is defined as the application of scientific knowledge for practical purposes.
We have advanced technological advancement which is why there won't be many discoveries in such time span.
