<u>Answer:</u> The time taken by jet plane to reach Los Angeles from Chicago is 3.5 hours
<u>Explanation:</u>
Speed is defined as the rate at which an object moves with respect to time.
To calculate the time taken for the given speed, we use the equation:

where,
s = speed of the jet plane = 800 km/hr
d = distance traveled = 2800 km
t = time taken by jet plane = ?
Putting values in above equation, we get:

Hence, the time taken by jet plane to reach Los Angeles from Chicago is 3.5 hours
Answer:
Mars
Explanation:
Terrestrial or inner planets like Mars and Venus were formed near the Sun where the solar system's temperatures were very high.
Answer:
A. an equal and opposite reaction force
Explanation:
This means that there is a natural reaction of force
<span>2Li⁺(aq) + Zn⁰(s) → 2Li⁰(s) + Zn²⁺(aq)
</span>2Li⁺(aq) + 2e⁻ → 2Li⁰(s)
Zn⁰(s) → Zn²⁺(aq) +2e⁻
2 electrons are transferred from atom of Zn⁰ to 2 ions of Li⁺.
