Answer:
t = 11.1 hours
Explanation:
The question says that, "A mobile advances at 20 m / s and travels a distance of 800 km. Determine the time in hours you use".
Given that,
Speed of a mobile, v = 20 m/s = 72 km/h
Distance, d = 800 km
We know that,
Speed = distance/time
So,

So, it will take 11.1 hours.
When there is no air resistance, objects of different masses dropped from rest:
a.
fall with equal accelerations and with equal displacements.
Answer:
all scenarios are using the same power
Explanation:
we know that power is defined as P(Watts)=W(Joules)/t(seconds).
When applying this formula to each of the scenarios we find:

Done
Answer:
Science is the intellectual and practical activity encompassing the systematic study of the structure and behaviour of the physical and natural world through observation and experiment.
