Answer:
38.8 km/hr
Explanation:
The total distance is 2 × 282 km = 564 km.
The total time is 6 hr 32 min + 8 hr = 14 hr 32 min = 14.533 hr.
The average speed is:
(564 km) / (14.533 hr)
38.8 km/hr
This type of energy is called non mechanical energy so the answer is C
Explanation:
It is known that the relation between force and acceleration is as follows.
F = -ma ............ (1)
Also, acceleration (a) = ......... (2)
The given data is as follows.
v = 0, u = 14 m/s, s = 1
Therefore, putting the values of expression (2) into expression (1) as follows.
F =
=
= 5978 N
thus, we can conclude that net force on the person if he or she is wearing a seat belt and if the air bag deploys is 5978 N.
Particles in the solar nebula were more spread out at greater distances, so that accretion took longer and there was less time to pull in gas before the solar wind cleared the nebula.
I believe it's true.Hope this helps.
