Answer:
Part (i) the magnitude of the vector is 5.315 m
Part (ii) the direction of the vector is 138.8⁰
Explanation:
Given;
y-component Ay = 3.50 m
x -component Ax = -4.00 m
Vector representation = (-4i + 3.5j)
Part (i) the magnitude of the vector
Magnitude of the vector = √(-4)² +(3.5)²
Magnitude of the vector = √28.25
= 5.315 m
Part (ii) the direction (in degrees counterclockwise from the +x-axis) of the vector.
If we make a rough sketch of this vector, the direction of this vector lies in second quadrant.
That is; 90 < θ < 180
Let's solve for θ
tan θ = y/x
tan θ = 3.5/-4
tan θ = - 0.875
θ = tan⁻¹ (-0.875)
θ = - 41.2⁰
Since θ lies in the second quadrant,
θ = - 41.2⁰ = 180 - 41.2 = 138.8⁰
The direction of the vector is 138.8⁰
Density of Earth: 5.514 g/cm³
Density of Jupiter: <span>1.326 g/cm³
1.326 g/cm³ / 5.514 g/cm³ </span>≈ <span>0,24
0,24 * 100 = 24%
Jupiter has 24% of earth's density.
(Density numbers are from internet, you may calculate with your own ones if u have )</span>
The object that a satellite revolves around is the <em>central body</em> of the system. <em>(C)</em>
For example:
-- The central body of the solar system is the Sun.
-- The central body for TV satellites, GPS satellites, weather satellites, and the International Space Station is the Earth.
-- The central body for Phobos and Deimos is Mars.
This should be a pretty easy question to answer by elimination, when you notice that "Orbit", "Period", and "Rotation" are not "Bodies".
