I choose the option D.
The velocity is constant, so it’s acceleration is 0 m/s^2.
X = 2 + 15 x 1 + 0 = 17 m
This is an example of conservation of angular momentum.
The ice skater will rotate more slowly because her arms would be considered the outside torque that is impacting her constant angular momentum.
So, an ice-skater who throws her arms out will rotate more slowly.
1. I think is letter b.
2. I thinks it's letter c.
A At one constant temp and another at a constant pressure
The four inner planets share several features in common.
(Mercury, Venus, Earth and Mars)
They are called terrestrial planets because they have solid, rocky surfaces roughly similar to desert and mountainous areas on the earth.
