The angle of the planet is mathematically given as
dY= 704 degrees
<h3>What angle has planet Y rotated through during this time?</h3>
With Kepler's third rule, which states that a planet's orbit squared is a function of cubed radius, we can prove that this is the case.
Generally, the equation for the period is mathematically given as
(periodX / periodY)^2 = (radius X / radius Y)^3
Therefore
(pX / pY)^2 = 4^3
(pX / pY)^2 = 64
\sqrt{(pX / pY )^2}= \sqrt{64}
(pX / pY=8
In conclusion, Because it takes 8 times longer to complete one orbit on planet X, planet Y travels 8 times farther than planet X does in the same time period...
planet Y travels ;
dY=8 * 88.0
dY= 704 degrees

Explanation:
Let
= distance traveled while accelerating
= distance traveled while decelerating
The distance traveled while accelerating is given by
We need the velocity of the rocket after 30 seconds and we can calculate it as follows:
This will be the initial velocity when start calculating for the distance it traveled while decelerating.
Solving for we get
Therefore, the total distance x is
Answer:
P = 86956.52 Pa
Explanation:
Data:
- F = 800 N
- A = 0.0092 m²
- P = ?
Use the formula:
Replace and solve:
The pressure it exerts on the ground is <u>86956.52 Pascal.</u>

Moment of inertia of N₂ molecule about an axis passing through the center of mass perpendicular to the line joining the two atoms=i=2.51 x 10⁻⁴⁷ kg m²
Explanation:
Moment of inertia= i= mr₁²+ mr₂²
m= mass of nitrogen atom=2.32 x 10⁻¹¹pg=2.32 x 10⁻²⁶ Kg
r1= r2=0.0465/2= 0.02325 nm=2.325 x 10⁻¹¹ m
so i= 2.32 x 10⁻²⁶ (2.325 x 10⁻¹¹)²+2.32 x 10⁻²⁶ (2.325 x 10⁻¹¹)²
i=2.51 x 10⁻⁴⁷ kg m²
