Answer:
PARABOLIC, EARTH, VERTICAL, INERTIAL ang PHYSICAL LAWS
Explanation:
In this exercise you are asked to complete the missing words.
When the steel ball falls on the constant speed car, it follows a PARABOLIC path in the reference frame fixed to EARTH, but a VERTICAL straight line in the reference frame of the constant speed car. Without a fixed frame of reference, you cannot tell whether or not you are in an INERTIAL frame of reference. All frames of reference that move at constant speed relative to each other are PHYSICAL LAWS__equivilent__.

Answer:
i) C decreases
ii) Q remains constant
iii) E remains constant
iv) ΔV increases
Explanation:
i)
We know, capacitance is given by:


<em>In this case as the distance between the plates increases the capacitance decreases while area and permittivity of free space remains constant.</em>
ii)
As the amount of charge has nothing to do with the plate separation in case of an open circuit hence the charge Q remains constant.
iii)
Electric field between the plates is given as:

where:
charge density, 
<em>As we know that distance of plate separation cannot affect area of the plate. Charge Q and permittivity are also not affected by it, so E remains constant.</em>
iv)
- From the basic definition of voltage we know that it is the work done per unit charge to move it through a distance.
- Here we increase the distance so the work done per unit charge increases.

Answer:
The maximum velocity is 0.489 m/s
Explanation:
Maximum velocity (v) = angular velocity (w) × radius (r)
w = 33.33 rpm = 33.33×0.1047 = 3.4897 rad/s
r = 14 cm = 14/100 = 0.14 m
v = 3.4897×0.14 = 0.489 m/s
Acceleration is a Vector, so speed and direction. If you change your direction you are also changing your acceleration because it's a vector.
