PE = (weight) x (height)
= (mass) x (gravity) x (height)
= (410 kg) x (9.8 m/s²) x (12 m)
= (410 x 9.8 x 12) kg-m²/s²
= 48,210 joules (rounded)
<span>Everything in the system is stable and therefore the objects motion is stable. That is to say it is not changing what it is already doing. As far as i know zero times zero is still zero. In that case then the motion must be constant or stable.</span>
Answer:
6.20×10⁴ V/m
Explanation:
The magnitude of electric field is:
E = √(Eₓ² + Eᵧ²)
where Eₓ = ∂φ/∂x and Eᵧ = ∂φ/∂y.
φ = 1.11 (x² + y²)^-½ − 429x
Eₓ = -0.555 (x² + y²)^-(³/₂) (2x) − 429
Eᵧ = -0.555 (x² + y²)^-(³/₂) (2y)
Evaluating at (0.003, 0.003):
Eₓ = -44034 V/m
Eᵧ = -43605 V/m
The magnitude is:
E = 61971 V/m
Rounded to three significant figures, the strength of the electric field is 6.20×10⁴ V/m.
Answer: 4.6 years
Explanation:
According to Kepler’s Third Law of Planetary motion <em>“The square of the orbital period 
of a planet is proportional to the cube of the semi-major axis 
(size) of its orbit”:
</em>
<em />
(1)
However, if is measured in Earth years, and is measured in astronomical units (unit equivalent to the distance between the Sun and the Earth), equation (1) becomes:
(2)
Knowing 
and isolating from (2):
(3)
(4)
Finally:
This is Ceres' orbital period
It has a flexible vertibrae which allows it to move faster and fit into places . Plus it also allows it to get its prey easier
