Both planets are similar in shape and have a rocky surface. Not sure about the phases though
Before the engines fail
, the rocket's horizontal and vertical position in the air are


and its velocity vector has components


After
, its position is


and the rocket's velocity vector has horizontal and vertical components


After the engine failure
, the rocket is in freefall and its position is given by


and its velocity vector's components are


where we take
.
a. The maximum altitude occurs at the point during which
:

At this point, the rocket has an altitude of

b. The rocket will eventually fall to the ground at some point after its engines fail. We solve
for
, then add 3 seconds to this time:

So the rocket stays in the air for a total of
.
c. After the engine failure, the rocket traveled for about 34.6 seconds, so we evalute
for this time
:

Answer:
<u>Charge</u><u> </u><u>of</u><u> </u><u>the</u><u> </u><u>particle</u><u> </u><u>is</u><u> </u><u>1</u><u> </u><u>coulomb</u><u>.</u>
Explanation:
Force, F:

F is magnetic force.
B is the magnetic flux density.
e is the charge of the particle.
V is the velocity

Answer:
Biodiversity.
Explanation:
The number of different species in a particular area is known as biodiversity. Blue whales, plants, different kind of animals, and micro-organism living in an ocean is the example of biodiversity. In biodiversity each specie has its own role. For example, if a biodiversity has large number of plants (species), it will have many type of crops.
