Here are the three observable facts that are explained by the nebular theory:
1) Planets all rotate in the same direction
2) Planets all orbit in within 6 degrees of a common plane
3) Planets within the orbit of the Asterioid Belt (terrestrial planets) are rocky while those outside it are gaseous.
Here are the missing statements and its appropriate labels:
all 6 of stars terrestrial planets have a moon as large as earth's moon - NOT CONSISTENT WITH THE THEORY
<span>a star is surrounded by a disk of gas but has no planets - CONSISTENT WITH THE THEORY</span>
<span>a star has 20 planets - CONSISTENT WITH THE THEORY</span>
<span>a stars 5 terrestrial planets orbit in the opposite direction of its 3 jovian planets - NOT CONSISTENT WITH THE THEORY</span>
<span>beyond its jovian planets, a star has two ice-rich objects as large as mars - CONSISTENT WITH THE THEORY</span>
<span>of a stars 5 terrestrial planets, 1 has a moon as large as earth's moon - CONSISTENT WITH THE THEORY</span>
<span>a stars 4 jovian planets formed in its inner solar system and its 4 terrestrial planets formed farther out - NOT CONSISTENT WITH THE THEORY</span>
<span>a star has 9 planets, but none orbit in close to the same plane - NOT CONSISTENT WITH THE THEORY</span>
Acceleration because it has a direction and magnitude
Answer:
a) 4.0 rad/s2
Explanation:
- For rigid bodies, Newton's 2nd law becomes :
τ = I * α (1)
where τ is the net external torque applied, I is the rotational inertia
of the body with respect to the axis of rotation, and α is the angular
acceleration caused by the torque.
- At the same time, we can apply the definition of torque to the left side of (1), as follows:
where τ = external net torque applied by Fnet, r is the distance
between the axis of rotation and the line of Fnet, and θ is the
angle between both vectors.
In this particular case, as Fnet is applied tangentially to the disk, Fnet
and r are perpendicular each other.
- Since left sides of (1) and (2) are equal each other, right sides are equal too, so we can solve for the angular acceleration as follows:
March has 31 days.
3 Marches have 93 days.
Each day has 86,400 seconds.
(93 days) x (86,400 sec/day) = 8,035,200 sec.
