Force F acts between two charges, q1 and q2, separated by a distance d. If q1 is increased to twice its original value and the d
Step2247 [10]
Okay, haven't done physics in years, let's see if I remember this.

So Coulomb's Law states that F = k \frac{Q_1Q_2}{d^2} so if we double the charge on Q_1 and double the distance to (2d) we plug these into the equation to find

<span>F_{new} = k \frac{2Q_1Q_2}{(2d)^2}=k \frac{2Q_1Q_2}{4d^2} = \frac{2}{4} \cdot k \frac{Q_1Q_2}{d^2} = \frac{1}{2} \cdot F_{old}</span>

So we see the new force is exactly 1/2 of the old force so your answer should be \frac{1}{2}F if I can remember my physics correctly.

The force (expressed in N), the egg experience upon hitting the ground is 3.5N.

<h3>What is Net force?</h3>

When two or more forces are acting on the system of objects, then the to attain equilibrium, net force must be zero.

Given is an 0.07 kg egg and toss if from a window 30 m above the ground. The egg reaches and maintains a falling speed of 0.5 m/sec. Upon reaching the ground, the egg rapidly decelerates to 0 m/sec over the course of only 0.01 seconds.

<h3>Average force = Mass x acceleration</h3>

F = m x (Vf -Vi)/t

F = 0.07 x (0 - 0.5)/0.01

F = -3.5N

Thus, the magnitude of force on egg upon hitting the ground is 3.5N.

What is horoscope? what is its uses
Lemur [1.5K]
What is horoscope?
A forecast of a person's future, typically including delineation of character and circumstances, based on the relative positions of the stars and planets at the time of that person's birth.

   *
A short forecast for people born under a particular sign, especially as published in a newspaper or magazine.
 
    *
A birth chart.
 

What is its uses?
It can also be calculated for an event, a question, and even a country. Symbols are used to represent planets, signs, and geometric connections called aspects. In most cases, the horoscope in Western astrology is drawn on a circular wheel.

The 400-turn primary coil of a step-down transformer is connected to an ac line that is 120 V rms. The secondary coil voltage is
KengaRu [80]

Explanation:

The given data is as follows.

             V_{1} = 120 V,    V_{2} = 6.50 V

             N_{1} = 400,     N_{2} = ?

Formula to calculate the number of turns in secondary coil are as follows.

          \frac{N_{1}}{N_{2}} = \frac{V_{1}}{V_{2}}

Putting the given values into the above formula as follows.

         \frac{N_{1}}{N_{2}} = \frac{V_{1}}{V_{2}}

        \frac{400}{N_{2}} = \frac{120}{6.50}

              N_{2} = 21.66

                          = 22 (approx)

Thus, we can conclude that number of turns in the secondary coil are 22.
