Answer:
Diurnal motion, apparent daily motion of the heavens from east to west in which celestial objects seem to rise and set, a phenomenon that results from the Earth's rotation from west to east. The axis of this apparent motion coincides with the Earth's axis of rotation. Retrograde motion is an APPARENT change in the movement of the planet through the sky. It is not REAL in that the planet does not physically start moving backwards in its orbit. It just appears to do so because of the relative positions of the planet and Earth and how they are moving around the Sun.
It would be from electrical to kinetic, so i would say a
Answer:
15.25 m/s
Explanation:
Velocity is given as;
v = angular velocity x radius
v = ωr
where;
v is velocity, ω = angular velocity and r is radius)
We are given;
ω = 50 rad/s
diameter = 61cm
So, radius = 61/2 = 30.5 cm = 0.305m
Plugging in the relevant values to get ;
v = 50 x 0.305
v= 15.25 m/s
Therefore the car is travelling at a constant speed of 15.25 m/s
Answer:
D. a cation that has a smaller radius than the atom.
Explanation:
When electrons are removed from the outermost shell of a calcium atom, the atom becomes a cation that has a smaller radius than the atom.
