Answer:
Yes cause he walks 6.7 miles
Evan could also grow some plants in the light? I don't have a clue but that would be my guess :) No points needed
Answer;
D. rocket engines are not dependent on oxygen from the air.
Explanation;
-Jet engines and rockets work on the same principle. They produce thrust through an internal pressure difference and, as explained by Newton’s Third Law of Motion, eject exhaust gases in an equal and opposite direction.
-The main difference between them is that jets get the oxygen to burn fuel from the air and rockets carry their own oxygen, which allows them to operate in space.
Additionally, Jet engines have two openings (an intake and an exhaust nozzle). Rocket engines only have one opening (an exhaust nozzle).
Answer:
a = 40 m / s²
Explanation:
This is a kinematics problem, where we must use both linear and angular and the relationship between them
we'll eat by reducing the angular velocity to units if
w = 1.0 rev / s (2pi rad / 1 rev) = 2pi rad / s
they ask us for linear acceleration, we use the relationships between linear or angular variables
a = α R
a = 20 2
a = 40 m / s²
The answer is C, all the other examples are examples of non renewable because they are burned and cannot be used again
