Answer:
a)
b)
Explanation:
From the exercise we got our <u>initial data</u>
a) To find <u><em>maximum height</em></u> we know that at that point
Solving for y
b) Since we know that the ball strikes the fairway 190 m away
Solving for t
Now, we can calculate the speed of the ball in both axes
The <em>negative</em> sign means the direction of the ball at that point.
Answer:
6.75m/s
Explanation:
using the second equation of motion, the time is calculated.
and with the formula a= (v - u)/t
where a is acceleration but in this case it's deceleration (and should be negated as you solve it ) .
v is final velocity
u is initial velocity
t is time taken
Answer:
nuclear envelope
Explanation:
it surrounds the nucleus and all of its contents
Most stars have one or more terrestrial planets orbiting within their habitable zones is the correct answer.
Explanation:
According to the science, the habitable zones are the region around the stars where one or more terrestrial planets can orbit. A terrestrial planet orbits inhabitable zone is called potentially habitable zone which have roughly comparable conditions to those of earth.
This situation is a proof stating that most of the stars have one or more terrestrial planets orbiting within their habitable zone.
