They determine if it has a negative or positive charge

Answer:

Well protons will contribute to what we all know as the mass of an atom, the number of protons always determine the exact identity of whatever Element you want to describe or find more about. The Electrons always have a negative charge, But because the atom is electrically Neutral, that must mean that the exact number of the Electrons will always equal up to the number of the Protons.

And I need help with seven and eight only I will appreciate it

Mumz [18]

Answer:

7] Force = mass × acceleration

Force = 2 × 5

Force = 10 N

8] Velocity = acceleration due to gravity × time taken

Velocity = 9.8 × 12

Velocity = 117.6 m/s

What is the formula to find the second charge in Coulomb's Law?

kicyunya [14]

Answer:

1.F is the electrostatic force between charges (in Newtons),

2.q₁ is the magnitude of the first charge (in Coulombs),

3.q₂ is the magnitude of the second charge (in Coulombs),

4.r is the shortest distance between the charges (in m),

5.ke is the Coulomb's constant. It is equal to 8.98755 × 10⁹ N·m²/C² .

A reactor operating at 1 MW is scrammed by instantaneous insertion of $5.00 of negative reactivity. Approximately how long does

Novosadov [1.4K]

Answer:

time is 3333.33 min or 55.55 hr

Explanation:

given data

reactor operating = 1 MW

negative reactivity = $5

power = 1 miliwatt

to find out

how long does it take

solution

we know here power coefficient that is

power coefficient = $\frac{10^{6} }{10^{6} }$

power coefficient = 1

so time required to reach power is

power = reactivity × time / power coefficient + reactor operating

1 × $10^{-3}$ = -5 t / 1 + 1 × $10^{6}$

5t = $10^{6}$ - $10^{-3}$

t = 199999.99 sec

so time is 3333.33 min or 55.55 hr
