Ok so light goes at a speed of <span>299,792 kilometers per second
so if my math is right 1.2 billion/299,792= 3335.646047926562 seconds

Answer:

Time, t = 4000 seconds

Explanation:

We know that,

1\ billion\ km=1.2\times 10^9\ km

1\ billion\ km=1.2\times 10^{12}\ m    

The speed of light, c=3\times 10^8\ m/s

Let t is the time taken by light. It can be calculated as :

t=\dfrac{d}{c}

t=\dfrac{1.2\times 10^{12}\ m}{3\times 10^8\ m/s}      

t = 4000 seconds

So, the time taken by the light is 4000 seconds, Hence, this is the required solution.

This is possible due to self-discharge. Very small internal currents inevitably occur in these cells over time and they will eventually exhaust the chemistry.

ludmilkaskok [199]

Answer:

a) 42 m/s, positive direction (to the east), b) 42 m/s, negative direction (to the west).

Explanation:

a) Let consider that Car A is moving at positive direction. Then, the relative velocity of Car A as seen by the driver of Car B is:

\vec v_{A/B} = \vec v_{A} - \vec v_{B}\\\vec v_{A/B} = 11 \frac{m}{s} \cdot i + 31 \frac{m}{s} \cdot i\\\vec v_{A/B} = 42 \frac{m}{s} \cdot i

42 m/s, positive direction (to the east).

b) The relative velocity of Car B as seen by the drive of Car A is:

\vec v_{B/A} = \vec v_{B} - \vec v_{A}\\\vec v_{B/A} = -31 \frac{m}{s} \cdot i - 11 \frac{m}{s} \cdot i\\\vec v_{B/A} = - 42 \frac{m}{s} \cdot i

42 m/s, negative direction (to the west).
