It <span>Ions were once atoms with the same number of electrons and protons. Since they have opposite charges atoms are neutral. When they become ions the lose or gain electrons and become unbalanced. ... These different charges are attracted to each other via electric forces.</span>

Solve this system of equations without graphing and show your reasoning <br><br> 5x+y=7<br> 20x+2=y
tatuchka [14]

Answer:

Explanation:

5x + y = 7

20x - y = -2

    25x = 5

        x = (1/5)

5(1/5) + y = 7

1 + y = 7 .

y = 6

The instantaneous emf resulting from magnetic induction equals the rate of change of flux is
katen-ka-za [31]

Lenz's Law: The polarity of the induced emf is such that it produces a current whose magnetic field opposes the change in magnetic flux through the loop.

An electron experiences a downward force of 12.8×10-19 N while traveling in a magnetic field of 8×10-5 T west, what is the magni
SashulF [63]

Answer:

v=10^5\ m/s

Explanation:

Given that,

Magnetic force acting on an electron, F=12.8\times 10^{-19}\ N

The magnitude of the magnetic field,B=8\times 10^{-5}\ T

We need to find the magnitude of the velocity. We know that the magnetic force is given by :

F=qvB

Where

v is the velocity

So,

v=\dfrac{F}{qB}\\\\v=\dfrac{12.8\times 10^{-19}}{1.6\times 10^{-19}\times 8\times 10^{-5}}\\\\v=10^5\ m/s

So, the magnitude of velocity is10^5\ m/s.

If this decay has half-life of 2 years, how many years would it take for 10.8 g Protactinium-231 to remain given an initial mass
sergij07 [2.7K]

Answer:

Time = 6 years

Explanation:

First, we will calculate the no. of half life periods required to reduce the mass of Protactinium to the given value:

m' = \frac{m}{2^{n} } \\\\2^n = \frac{m}{m'}

where,

n = no. of half-life periods = ?

m = initial mass = 86.3 g

m' = remaining mass = 10.8 g

Therefore,

2^n = \frac{86.3\ g}{10.8\ g}\\\\2^n = 8\\2^n = 2^3

Since the bases are the same. Therefore equating powers:

n = 3

Now we calculate the time:

Time = (n)(Half-Life)\\Time =(3)(2\ years)

<u>Time = 6 years</u>
