Answer:
25km/h
Explanation:
This is a trick question, the average speed in this case does not really depend on calculation or extrapolation, it just refers to an event that is yet to occur,
In other words, if you want to achieve an average speed of 25km/h for 23km, then you should drive your car at a constant speed of 25km/h, any variation in speed may cause a change in your average speed at the end.
Answer:
Since the momentum of the body remains constant ( conserved) the trolley slows down (its velocity reduces) since its mass increases.
Answer:
slightly higher than y
Explanation:
The initial/previous upward component of the bullet's velocity does not really have effect on the constant downward acceleration due to gravity. Since you must aim upward, there will be less or declined horizontal velocity, therefore it will take more time for the bullet to get to the plane of the target or aim. The bullet will now have more time to drop away from the straight line path along which it was aimed.
Furthermore, this problem assumes ideal or perfect conditions (no effects from air resistance). The high speed of a bullet has no much or less effect in this regards.
The just-world phenomenon is the belief that everything that happens to an individual is due to the individual's actions; in other words, all good and all bad that an individual encounters in the world is deserved by that person. This leads to a victim being blamed with the logic that "they had it coming" and someone who encounters good fortune being praised with "they earned it". Therefore, in this scenario, people will assume that Rose's inheritance is well deserved.<span />
Answer:
New Moon - Crescent Moom ---- Full Moon ---- Waning Quarter
Explanation:
The Moon revolves around the Earth in a 28 day period, which is approximately one Earth month, therefore S the student has been recording the movement of the Moon for 4 Earth weeks this is a period of complete revolution of the Moon .
Consequently you must register the following phases
New Moon - Crescent Moom ---- Full Moon ---- Waning Quarter
in the period where it begins, it must go through the cycle in an orderly way to the right.
