The potential difference between two parallel plates is related to the electric field intensity by
where
is the potential difference
E is the electric field intensity
d is the distance between the two plates.
In our problem,
and
so we can calculate the potential difference as
Answer:
Centripetal acceleration
Explanation:
Centripetal force tends to keep an object moving within a circular or curved path to maintain its course while centripetal acceleration is what tends to accelerate the object towards the centre of the curve or circle
KINEMATICS
Uniform or constant motion in a straight line (rectilinear). Speed or velocity constant and/or acceleration constant. If motion is up and down and/or has an up and down component then acceleration omn earth will be g. g is about 10m/s/s.
speed = distance/time
velocity = displacement/time
s=distance ... u=initial speed ... v = final speed ... a = acceleration ... t = time
v=u+at
v^2=u^2+2as
s=ut+1/2at^2
Answer: If a force on an object is aimed in the direction of the object’s velocity, the force does positive work
(b).
Explanation:
Hi, the answer is oprion b. positive work.
If a force on an object is aimed in the direction of the object’s velocity, the force does positive work.
An object's kinetic energy will only change if the force acting on the object changes the object's speed. This will only happen if there is a component of the force in the direction that the object moves.
So, A force will do work only if the force has a component in the direction that the object moves.
