<h2>Answer:</h2>

<u>By changing the position of the fulcrum, the amount of effort Force also changes</u>

<h2>Explanation:</h2>

The mechanical advantage of a lever is changed when the distance between the pivot point (fulcrum) and the weight is changed. The way levers operate is by an effort applied at a point, which moves a load at another point through a balance point called the fulcrum. If the distance between the fulcrum and the effort is increased, the effort needed to lift a weight decreases proportionally.

Air will break down (lose its insulating quality) and sparking will result if the field strength is increased to about 3 × 106 N
MrRissso [65]

Answer:

Acceleration,a=5.27\times 10^{17}\ m/s^2

Explanation:

Given that,

Electric field strength, E=3\times 10^6\ N/C

Mass of the electron, m=9.109\times 10^{-31}\ kg

Charge on electron, q=1.602\times 10^{-19}\ C

Let a is the acceleration experienced by an electron. It can be calculated as :

ma=qE

a=\dfrac{qE}{m}

a=\dfrac{1.602\times 10^{-19}\times 3\times 10^6}{9.109\times 10^{-31}}

a=5.27\times 10^{17}\ m/s^2

Hence, this is the required solution.

What is the energy of the electron in a helium ion with a charge of +1 in an orbit with a value of n=4?
goldenfox [79]

Answer:

The energy of the electron in a helium ion is -5.44\times10^{-19}\ J

Explanation:

Given that,

Charge = +1

Value of n = 4

Suppose k=2.179\times10^{-18}\ J

We need to calculate the energy of the electron in a helium ion

Using formula of energy

E_{n}=-k\dfrac{z^2}{n^2}

Put the value into the formula

E_{n}=-2.179\times10^{-18}\times\dfrac{2^2}{4^2}

E_{n}=-5.44\times10^{-19}\ J

Hence, The energy of the electron in a helium ion is -5.44\times10^{-19}\ J
