Answer:
your mum because I don't know how to explain why she was doing it but I think I have to do it myself again but it was just the way
I think its a metamorphic rock because i know 100% that a metamophic rocks are created by heat and pressure
Answer:
0.00712 m
Explanation:
Given:
Charge on first particle (q₁) = 75 nC = 
Charge on second particle (q₂) = 75 nC = 
Force (F) = 1.00 N
Separation (d) = ?
The magnitude of force is given by Coulomb's law which states that, the magnitude of force acting between two charged particles separated by a distance is directly proportional to the product of the magnitudes of charges and inversely proportional to the square of the distance between them.
Therefore, the magnitude of force is given as:

Where,
is the coulomb's constant.
Plug in the given values and solve for 'd'. This gives,

Therefore, the distance between the charges is 0.00712 m.
Answer:
It's actually 100V
Explanation:
To answer this, you'd need to use Ohm's law, which states that Voltage is equivalent to the product of Current and Resistance (V=IR).
V = 50 × 2
V = 100
Therefore the voltage is a 100V.
None of the answers you have listed match this though, so I'm guessing it either must be typo or the question itself is wrong.
The answer is: [C]: "protons and electrons" .
