Answer:
The closer two charged objects are the stronger the electrical force between them.
Like charges repel and opposite charges attract.
The further away two charged objects are the weaker the electrical force between them.
Explanation:
Coulomb's law tells us about the electric force/electrostatic force/Coulomb force between two charged particles. The force (F) between the particles Q and q, separated by a distance r is given as,
where k = Coulomb constant.
It is evident from the equation that closer the charged particle force will be more. As the distance between the charge increases the force will be weaker. Also the like charges will repel and opposite charges will attract.
Answer:
I know for sure that it's either A or B have a great day sorry I don't know which one completely
Just took that test the answer is perpendicular to the wave motion
Answer:
a
Explanation:
because it has compact molecules
Answer:
√(6ax)
Explanation:
Hi!
The question states that during a time t the motorcyle underwent a displacement x at constant acceleration a starting from rest, mathematically we can express it as:
x=(1/2)at^2
Then the we need to find the time t' for which the displacement is 3x
3x=(1/2)a(t')^2
Solving for t':
t'=√(6x/a)
Now, the velocity of the motorcycle as a function of time is:
v(t)=a*t
Evaluating at t=t'
v(t')=a*√(6x/a)=√(6*x*a)
Which is the final velocity
Have a nice day!
