Answer:
D). Uranus.
Explanation:
Jovian planets are described as the planets which are giant balls of gases and located farthest from the sun which primarily include Jupiter, Saturn, Uranus, and Neptune.
As per the question, 'Uranus' is the jovian planet that would have the most extreme seasonal changes as its tilted axis leads each season to last for about 1/4 part of its 84 years orbit. The strong tilted axis encourages extreme changes in the season on Uranus. Thus, <u>option D</u> is the correct answer.
Answer:
1.1x10^-2N
Explanation:
We have the change in momentum as
P = 0.3(4.5+12)g.mph
= 0.3x0.447x(4.5+12)x10^-3
Then the force that is exerted will be
F = p/∆t
∆t = 0.2
= 0.3x0.447x(4.5+12)x10^-3/0.2
= 0.1341x16.5x10^-3/0.2
= 1.1x10^-2
Therefore the force that was exerted is equal to 1.1x10^-2

Answer:
F = 4117.64
Explanation:
First, we will calculate the acceleration of the hand, by using the third equation of motion:
where,
a = acceleration = ?
s = distance covered = compression = 8.5 cm = 0.085 m
vf = final speed = 0 m/s
vi = iniial speed = 10 m/s
Therefore,
negative sign hows deceleration.
Now, we will calculate the force exerted by the hand:
<u>F = 4117.64 N</u>
