1. The basic building block of matter are atoms. Every atom is basically a tiny sphere. Every atom is composed of 2 regions, the

outer part of the sphere is called the _______ and accounts for about 99.95% of the volume of an atom. 2. The electron cloud is the region of an atom in which the __________ are found. __________ are tiny particles with a -1 electrical charge and almost no mass. Electricity is _________ flowing though a conductor, usually metal. 3. Every atom is composed of 2 regions. The very tiny center part of the spherical atom is called the _____________. The __________ accounts for about 99.95% of the mass of the atom even though it has almost no volume. 4. Every atom has a nucleus. The nucleus contains 2 different types of particles. The particle with the +1 electrical charge is called the __________. It has almost 2000 times more mass than an electron. The number of __________ in the nucleus determine how many electrons the neutral atom has and all of the chemical reactions the atom can do. 5. Every atom has a nucleus.

The +1 charged protons would repel each other and destroy the nucleus if the _______________ were not neutralizing the repulsive force between the protons. 6. When graphing how the experimental “effect” depends on the experimental “cause”, the graph can show either a _______________ or an inverse relationship or no relationship. If the “effect” (dependent variable) value increases when we make the “cause” (independent variable) value increase, then we call this a ____________________. 7. When graphing how the experimental “effect” depends on the experimental “cause”, the graph can show either a direct relationship or an ______________ or no relationship. If the “effect” (dependent variable) value decreases when we make the “cause” (independent variable) value increase, then we call this an ____________________. 8. When graphing how the experimental “effect” depends on the experimental “cause”, the graph can show either a direct relationship or an inverse relationship or _____________. If the “effect” (dependent variable) value doesn’t change when we make the “cause” (independent variable) value increase, then we call this ____________________. 9. An experiment needs an _________________ to validate its results. The ________________ can be one of 2 things. The __________________ can be a set of experimental conditions we repeat several times throughout the experiment. Or the ________________ can be a set of conditions which other experimenters have used and is considered “normal” or “state of the art.” 10. A variable is something which can change during an experiment. It works best when we only let 2 variables change. All the rest are kept constant and are called _______________. fill in the blanks with these words.

The answers would be:

1. Electron cloud

2. Electrons, Electrons, Electrons

3. Nucleus, nucleus

4. Protons, protons

5. Neutrons, Neutrons

6. Direct, direct.

7. Inverse, inverse

8. No relationship, no relationship

9. Experimental control

10. Controlled variables

Here is more about the question:

An atom has 3 subatomic particles:

Proton: positively charged particles

Electron: Negatively charged particles

Neutrons: Neutrally charged particles

The nucleus is made up of the protons and neutrons, while the electrons are found outside, within the electron cloud.

Electrons are very important in bonding. It is also heavily involved in electricity. Electricity is the flow of electrons through a conductor.

Relationships in a graph:

For direct relationships, you just need to remember, when one goes up, the other one goes up too.

Inverse relationships on the other hand, when one goes up the other goes down.

If no change occurs, then we can say that there is no relationship.

In a 49 s interval, 595 hailstones strike a glass window of an area of 0.954 m at an angle of 25° to the window surface. Each ha
eduard

Average  force on the window: 0.32 N

Explanation:

The average force exerted on the window is given by Newton's second law

F=\frac{\Delta p}{\Delta t}

where

\Delta p is the net change in momentum of the hailstones in a time interval of \Delta t

In order to find the change in momentum, we have to consider only the component of the hailstone's momentum perpendicular to the window, therefore:

p_i =m u sin \theta is the initial momentum of one hailstone, with

m = 7 g = 0.007 kg is the mass

u=4.5 m/s is the initial speed

\theta=25^{\circ} is the angle with the window

The final momentum is

p_f = mv sin \theta

where

v = 4.5 m/s is the final speed (the  collision is elastic so the speed is equal, while the direction changes)

\theta=-25^{\circ} (after the rebound, the direction has changed)

So the change in momentum of 1 hailstone is

\Delta p = mv sin(-25^{\circ})-mu sin(25^{\circ})=-2mu sin(25^{\circ})=-0.0266 kg m/s

We are interested only in the magnitude, so

\Delta p = 0.0266 kg m/s

There are 595 hailstones hitting the window in 49 s, so the total change in momentum is

\Delta p = 595\cdot 0.0266 = 15.8 kg m/s

And therefore, the average force on the window is

F=\frac{\Delta p}{\Delta t}=\frac{15.8}{49}=0.32 N

In a region of space where gravitational forces can be neglected, a sphere is accelerated by a uniform light beam of intensity 8
BlackZzzverrR [31]

Answer:

The correct answer is B

Explanation:

To calculate the acceleration we must use Newton's second law

      F = m a

      a = F / m

To calculate the force we use the defined pressure and the radiation pressure for an absorbent surface

       P = I / c        absorbent surface

       P = F / A

       F / A = I / c

       F = I A / c

The area of ​​area of ​​a circle is

      A = π r²

We replace

     F = I π r² / c

Let's calculate

     F = 8.0 10⁻³ π (1.0 10⁻⁶)²/3 10⁸

     F = 8.375 10⁻²³ N

Density is

      ρ = m / V

      m = ρ V

      m = ρ (4/3 π r³)

      m = 4500 (4/3 π (1 10⁻⁶)³)

      m = 1,885 10⁻¹⁴ kg

Let's calculate the acceleration

     a = 8.375 10⁻²³ / 1.885 10⁻¹⁴

     a = 4.44 10⁻⁹ m/s²               absorbent surface

The correct answer is B

As SCUBA divers go deeper underwater, the pressure from the weight of all the water above them increases tremendously which comp
faltersainse [42]

Answer:  The volume of gas expands because of the decrease in pressure as he tries to exit the water body, therefore he must take necessary precaution.

Explanation:

Using Boyle's law which states that the  the pressure of a given mass of an ideal gas is inversely proportional to its volume at a constant temperature

ie P1VI=P2V2

A diver absorbs compressed nitrogen gas when  he dives into the water body, As he ascends  out of the water body having less pressure, the volume of nitrogen gas which he absorbs will tend to expand following  Boyle's Law.  Therefore a scuba driver should not rises quickly but slowly  to the surface or else the  expanding nitrogen gas can cause tiny bubbles in his blood and tissue to form together with joints pains and eventually  cause decompression sickness needing medical attention.
