Answer:
Combination circuit; The basic strategy for the analysis of combination circuits involves using the meaning of equivalent resistance for parallel branches to transform the combination circuit into a series circuit.
Example:
The use of both series and parallel connections within the same circuit. In this case, light bulbs A and B are connected by parallel connections and light bulbs C and D are connected by series connections. This is an example of a combination circuit.
Answer: parabola
Explanation:
•Parabolic Trajectory:
In conclusion, projectiles travel with a parabolic trajectory due to the fact that the downward force of gravity accelerates them downward from their otherwise straight-line, gravity-free trajectory.
Answer:
(a): The launch velocity is Vx= 666.66 m/s.
(b): The angle wich the projectile contacts the ground is α= 0.38°
Explanation:
h= 1m
g= 9.8 m/s²
h= g*t²/2
t= 0.45 s
Vy= g*t
Vy= 4.42 m/s
d=Vx* t
Vx= 666.66 m/s (a)
α= tg⁻¹ ( Vy/Vx)
α= 0.38° (b)
