How does increasing the amount of charge on an object affect the electric force it exerts on another charged object?
gregori [183]

Hi Mandy!

Question - How does increasing the amount of charge on an object affect the electric force it exerts on another charged object?

Answer - The electric force increases because the amount of charge has a direct relationship to the force.

Why - The affect that the force exerts on another object that is also charge is becase the fact that when the electric force increases is when the charge is direct with the object with the force.

Hope This Helps :)

A person travels by car from one city to an-
Mademuasel [1]
<h2>Answer:</h2>

<h2>Explanation:</h2>

First, let's refer to the distance formula:

d=v*t, where d is distance, v is velocity or speed and t is time.

Now, let's find the distance covered by each individual speed that the car had:

<h3>1. Speed 1.</h3>

In order to use the formula, we need to convert minutes into hours since the speed is given in km/h.

21.1 min/60= 0.35 h.

Now, apply the distance formula.

d=(0.35h)*(86.8km/h)= 30.38 km.

<h3>2. Speed 2.</h3>

Convert minutes to hours again and do the same calculations.

10.6min/60=0.18h

d=(0.18h)*(106km/h)= 19.08 km.

<h3>3. Speed 3.</h3>

36.5min/60= 0.61h

d=(0.61h)*(30.9km/h)= 18.85 km.

<h3>4. Obtain the total distance.</h3>

The total distance must be given by the addition of all individual distances traveled by the car on each speed:

Total distance= 30.38 km + 19.08 km + 18.85 km= 68.31 km.

In electromagnetic waves, frequency is inversely proportional to
forsale [732]
Frequency is inversely proportional to wavelength.

Wavelength is the spacial period, and more generally the frequency is inversely proportional to the period.

If the wave's speed if c, then f=c/l where l is the wavelength.

Consider a step-down transformer with 15 turns in the primary and 6 turns in the secondary windings. Calculate the input impedan
AURORKA [14]

Answer:

Input impedance of this transformer is 50 ohms.  

Explanation:

Given that,

Number of turns in the primary coil, N_p=15

Number of turns in the secondary coil, N_s=6

Output impedance of the transformer, V_o=8\ \Omega

The number of turns and the impedance ratio in the step down transformer is given by :

\dfrac{15}{6}=\sqrt{\dfrac{Z_p}{Z_s}}\\\\\dfrac{15}{6}=\sqrt{\dfrac{Z_p}{8}}\\\\Z_p=50\ \Omega

So, the input impedance of this transformer is 50 ohms. Hence, this is the required solution.
