I'm guessing that the question is how much force is pulling the two charges together. I'll use Coulomb's law where Force = k*Q1*Q2/r^2, where k is Coulomb's Constant= 8.99*10^9. First, r = distance between points = sqrt((0.150+0.15)^2+0^2) = 0.3 Entering this info into the equation = (8.99*10^9)*(6*10^-9)*(6*10^-9)/(0.3)^2 = 3.60*10^-6 Newtons away from each other They repel since both are positive).

Finger [1]

B. Kilopascals.

A kilopascal equals to 1,000 pascals; and a pascal is equal to a force of 1 newton per square meter.

Meanwhile,

- a gram and a kilogram are both units of measurement for mass, and

- a newton is a unit of measurement for force.

18) A charm quark has a charge of approximately
Allushta [10]

Based on scientific records, a charm quark has a charge that's approximately equal to: 2) 1.07 × 10⁻¹⁹ C.

<h3>What is a charge?</h3>

A charge simply refers to a fundamental, physical property of matter that governs how the particles of a substance are affected by an electromagnetic field, especially due to the presence of an electrostatic force (F).

Also, charge is typically measured in Coulombs and a charm quark (elementary particle) has a charge that's approximately equal to 1.07 × 10⁻¹⁹ Coulomb.

When the diaphragm contracts , air pressure in the chest increases . True or False ?
nexus9112 [7]

Answer: False

 

When the diaphragm contracts, the muscles will also contract and pull upward and increase the size of the thoracic cavity thus decreases air pressure inside during inspiration. After the diaphragm contracts, it goes to relaxation, the muscles will also relaxed. It gets looser and return to its original position higher up in the chest. This increase the pressure in the chest, which force the air in the lungs out through the nose.

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.

Soccer fields vary in size. a large soccer field is 115 m long and 85 m wide. what are its dimensions in feet and inches? (assum
Irina18 [472]

The dimension of soccer field in ft is 377.315 ft long and 277.885 ft in width.

The dimension of soccer field in ft is 4527.78 in long and 3334.62 in in width.

As it is given that 1 m =3.281 ft

Therefore the length of the soccer field in ft is

115*3.281=377.315 ft

And width of the field is 85*3.281=277.885 ft

We know that 1 ft =12 in

Therefore the length of the soccer field in in is

377.315*12=4527.78 in

And width of the field is 277.885 *12=3334.62 in
