Two charged particles are a distance of 1.82 m from each other. One of the particles has a charge of 7.52 nC, and the other has

elena55 [62]

Answer:

(a) $F=9.10*10^{-8}N$

(b) The force is repulsive

Explanation:

a) According to Coulomb's law, the magnitude of the electrice force that one particle exerts on the other is defined as:

$F=\frac{kq_1q_2}{d^2}$

Here k is the coulomb constant, $q_1$ and $q_2$ are the signed magnitudes of the charges and d is the distance between them.

$F=\frac{8.99*10^{9}\frac{N\cdot m^2}{C^2}(7.52*10^{-9}C)(4.46*10^{-9}C)}{(1.82m)^2}\\F=9.10*10^{-8}N$

b) According to Coulomb's law, if the two charges have the same sign, the electrostatic force between them is repulsive.

What region of the electromagnetic spectrum contains wavelengths the size of an atom? (10^-10 meters) What frequency does this w

DENIUS [597]

If a photon has a wavelength of about 10^-10 meters, it would be certainly in the X rays region and it would have a frequency of 2.99792458x10^18 Hz, that you can easily calculate using the relation that states that the product of the wavelength and the frequency of an electromagnetic wave aka light is always equal to 299,792,458 m/s which is the exact value of the speed of light!

Where in the dive above would kinetic energy and potential energy be equal?

Diano4ka-milaya [45]

Answer: The sum of an object's potential and kinetic energies is called the object's mechanical energy. As an object falls its potential energy decreases, while its kinetic energy increases. The decrease in potential energy is exactly equal to the increase in kinetic energy.

As a baseball is being caught, its speed goes from 43 to 0 m/s in about 0.003 s. Its mass is 0.145 kg. (Take the direction the b

juin [17]

The question is incomplete, these are the missing parts of the question.

b) What is the baseball's acceleration in g's? (Indicate the direction with the sign of your answer.)

(b) What is the size of the force acting on it?

Answer:

a) -14333.3ms-2

b) -1462.58g

c) 2078N

Explanation:

The acceleration (deceleration) is easily found from from the information provided. Then the acceleration is obtained in terms of g as shown in the solution attached. The force is obtained from F=ma as shown in the image attached. Note the acceleration is negative because the ball was coming to rest. (The ball was caught).
