The correct answer is
<span>B. if Earth rotated on an axis that was not tilted with respect to Earth's orbit
In fact, the fact that Earth's axis is tilted is the reason why the durations of day and night are different in every part of the Earth. If the axis was not tilted, we would have exactly 12 hours of day and night in every point of the Earth, for the whole year.</span>
Answer:
v = 8 [m/s]
Explanation:
Debemos determinar la velocidad promedio, esta velocidad se define como la relacion entre la distancia recorrida sobre un determinado tiempo.
De esta manera tenemos la siguiente expresion:
v = x/t
donde:
v = velocidad [m/s]
x = distancia = 400 [m]
t = tiempo = 50 [s]
v = 400/50
v = 8 [m/s]
When energetic UV rays dissociates molecules of oxygen into seperate atoms. But when they collide into each other it forms OZONE.
Answer:
-8 Kgm/s
Explanation:
From the law of conservation of moentum, the sum of momentum before collision equals the sum of momentum after collision. Therefore
Before collision
Momentum =+15 kgm/s+-35 kgm/s=-20 kgm/s
After collision
Momentum=-12 kgm/s +x kgm/s
x-12 kgm/s=-20 kgm/s
x=-20+12=-8 Kgm/s
The answer is true because A current carrying wire is surrounded by magnetic field
