Answer:

Explanation:
The magnitude of the electric field between two parallel conducting plates is defined as:

Here
is the potential difference between the plates and d its separation.
The electric potential energy is defined as the product between the particle's charge and the potential difference:

Solving for
and replacing in the electric field formula:

In this case we have a double charged ion, so
:

i'd say false, is this for health or lifeskills?
Answer:
Er = 108 [J]
Explanation:
To solve this problem we must understand that the total energy is 200 [J]. Of this energy 44 [J] are lost in sound and 48 [J] are lost in heat. In such a way that these energy values must be subtracted from the total of the kinetic energy.
200 - 44 - 48 = Er
Where:
Er = remaining energy [J]
Er = 108 [J]
The answer is step by step 65
