Answer:
The charges under study are of the same sign
The calculation of the electric field for each charge separately, there is no relationship between the charges
Explanation:
Let's start by writing the equation for the electric field
E = k q / r²
where q is the charge under analysis and r the distance from this charge to a positive test charge.
When analyzing the statement the student has some problems.
* The charges under study are of the same sign, it does not matter if positive or negative.
* The calculation of the electric field for each charge separately, there is no relationship between the charges for the calculation of the electric field.
* What is added is the interaction of the electric field with the positive test charge, in this case each field has the opposite direction to the other, so the vector sum gives zero
Newton's Third Law- For every action there is an equal and opposite reaction... Does this answer your question? If not, I can explain further...
Cats have tails to help their balance. Similar to the stick a trapeze/high wire walker uses.
The tail helps to serve as a counterbalance when cats walk on narrow spaces such as fences or shelves. The tail also aids in balance when a cat is running after or jumping on prey.
Just so you know....Cats can live without tails.
Answer:
7.65 m
Explanation:
= Initial pressure = 0.03 atm
= Final pressure = 1 atm
= Inital radius = 21 m
= Intial volume of gas = 
= Final volume of gas = 
= Initial temperature = 200 K
= Final temperature = 323 K
From ideal gas law we have
The radius at liftoff is 7.65 m
