In the equation F = Kq1 q2/r2 solve for q2. Solve for r.

Tpy6a [65]

Answer:

r = √(k q₁ q₂ / F)

Explanation:

F = k q₁ q₂ / r²

Multiply both sides by r²:

F r² = k q₁ q₂

Divide both sides by F:

r² = k q₁ q₂ / F

Take the square root of both sides:

r = √(k q₁ q₂ / F)

The fastest measured pitched baseball left the pitcher's hand at a speed of 42.0 m/s. If the pitcher was in contact with the bal

I am Lyosha [343]

Answer:

The acceleration and time are 588 m/s² and 0.071 sec respectively.

Explanation:

Given that,

Speed = 42.0 m/s

Distance = 1.50 m

(a). We need to calculate the acceleration

Using equation of motion

$v^2=u^2+2as$

$a=\dfrac{v^2-u^2}{2s}$

Put the value in the equation

$a=\dfrac{42.0^2-0}{2\times1.50}$

$a=588\ m/s^2$

(b). We need to calculate the time

Using equation of motion

$v = u+at$

$t=\dfrac{v-u}{a}$

$t=\dfrac{42.0-0}{588}$

$t=0.071\ sec$

Hence, The acceleration and time are 588 m/s² and 0.071 sec respectively.

In the film, 2001: A Space Odyssey, astronauts travel through space and experience artificial gravity created by a spinning, cyl

katrin2010 [14]

Artificial gravity is created by rotating the cylinder

So here we can say that the acceleration is due to centripetal acceleration

So here we know that the formula of centripetal acceleration is given by

$a_c = \frac{v^2}{R}$

so here we know that

$a_c = 9.8 m/s^2$

$v = 30.9 m/s$

now we will plug in all values

$9.8 = \frac{30.9^2}{R}$

$R = \frac{30.9^2}{9.8}$

$R = 97.43 m$

So above is the radius of the cylinder

Now to find the diameter

$d = 2R$

$d = 2*97.43$

$d = 194.8 m$

so its diameter is 194.8 m

What is the best use of an atomic model to explain the charge of the particles in Thomson’s beams?

kodGreya [7K]

Answer:

The interpretation of the subject in question is characterized in the discussion section below.

Explanation:

The atom seems to be the smallest particle of negatively charged electrons as well as positive. The negative particulates are comparatively small, as well as distant from both the considerably high beneficial particles. When the negative objects traveled away from the desired ones those who formed an intangible beam which was electrically charged.
Thomson would use a closed glass globe with just a single positive and another negative electrode with extraordinarily low present pressure. He was forced to submit those other gases to quite a voltage level, and also that the rise in popularity of emission levels, which have been called cathode rays, must have been observed.
As the negatives shifted away from those in the positives, an imaginary electrically conductive beam was formed. Not only that but the negative particles have been completely circumvented due to the extreme distance seen between positively and negatively particle size.
