Which of the following accurately describes properties of valence?A. The smaller the number of electrons an atom has to borrow or to lend, the greater the activity of the atom.
B. Nonmetallic elements tend to have a positive valence and tend to be electron borrowers.
C. Metals tend to have a negative valence and tend to be electron borrowers.
D. The greater the number of electrons an atom has to borrow or to lend, the greater the activity of the atom

Answers

Answer 1
Answer: Atoms, the main constituents of matter, consist of positively charged protons and neutral neutrons within a nucleus which are surrounded by a sea of electrons that sit in distinct shells. The electrons on the outer shell are known as valence electrons. The valence can be descibed as the smaller number of electrons an atom has to borrow or to lend, the greater the activity (A).

During the motion of the slinky in a transverse wave, what do the particles of the slinky coil do?Question 3 options:

the slinky particles move from the hand down the wave to the block


the slinky particles move side to side


the slinky particles move up and down

Answers

The characteristics of the traveling waves we can find the correct answer for the movement of the particles in the transverse wave is:

  • The slinky particles move up and down.

The traveling wave movement is a way of transmitting energy without mass movement, it is formed by two movements united, an oscillatory movement and a displacement movement, there are two possibilities:

  • Longitudinal wave. In this case, the oscillation of the particles is in the same direction as the movement of the wave.
  • Transversal wave. The oscillation of the particle is perpendicular to the movement of the wave, see attached.

In both cases, the matter particles are oscillating around their equilibriumposition and the wave is the one that has a displacement movement.

Let's review the claims:

a) False. The particle has an oscillatory motion, it does not have a net displacement

b) False. The movement is oscillatory

c) True. As the wave is transversal, the oscillatory movement from top to bottom.

In conclusion using the characteristics of the traveling waves we can find the correct answer for the motion of the particles in the transverse wave is:

  • the slinky particles move up and down

intravenous infusions are usually made with the help of the gravitational force. assuming that the density of the fluid being administered is 1,020 kg/m3, at what height should the iv bag be placed above the entry point so that the fluid just enters the vein if the blood pressure in the vein is 2.7 x 103 pa above atmospheric pressure? assume that the iv bag is collapsible. (hint: atmospheric pressure is applicable in the entire situation)

Answers

The IV bag should be placed approximately 10.19 meters above the entry point to ensure that the fluid just enters the vein, considering the blood pressure in the vein and assuming atmospheric pressure is applied.

Given:

Density of the fluid being administered = 1,020 kg/m³

Blood pressure in the vein = 2.7 × 10³ Pa above atmospheric pressure

Since the fluid is administered using gravitational force, the pressure at the entry point of the vein should be higher than the pressure at the IV bag.

The pressure difference can be calculated using the formula:

Pressure difference = density × gravitational acceleration × h

The pressure difference should be equal to the sum of the blood pressure in the vein and the atmospheric pressure:

Pressure difference = (blood pressure in the vein) + (atmospheric pressure)

h = (pressure difference) / (density × gravitational acceleration)

h = [(2.7 × 10³) + (101,325)] / (1,020 × 9.8)

h ≈ 10.19 meters

Therefore, the IV bag should be placed approximately 10.19 meters above the entry point to ensure that the fluid just enters the vein, considering the blood pressure in the vein and assuming atmospheric pressure is applicable throughout the situation.

Question 1: Hypothesis and Data CollectionFill the balloon with water until it is the size of a golf ball, and tie a knot in the end. Make sure there are no air bubbles in the balloon. In the plastic container, mix the plaster of Paris powder with water until it is as thick as yogurt, and then press the balloon into the center. One-third of the balloon should be below the surface of the plaster. Set the container aside until the plaster sets.

Part A
In this experiment, you will place the container in the freezer. What do you think will happen?

Answers

Hypothesis: When the container with the balloon and plaster of Paris is placed in the freezer, the water inside the balloon will freeze and expand as it turns into ice. As the water freezes, it will exert pressure on the plaster, causing the plaster to crack or deform. The extent of cracking or deformation may depend on the strength and thickness of the plaster.

Part B of the experiment would typically involve conducting the experiment and observing the actual outcome to confirm or reject the hypothesis.

Which type of energy transfer occurs when a beaker of water is heated on a hot plate?

Answers

Answer:

Convection is the transfer of thermal energy from one place to another by the movement of gas or liquid particles. How does this happen? As a gas or liquid is heated, the substance expands. This is because the particles in liquids and gases gain kinetic energy when they are heated and start to move faster.

Suppose that a sled is accelerating at a rate of 2 m/s2. If the net force is tripled and the mass is halved, then what is the new acceleration of the sled?(show how you solved it)

Answers


Start with Newton's 2nd law of motion:

                             Force = (mass) x (acceleration) .

Since we're going to be talking about acceleration,
lets divide each side by (mass):

                             Acceleration = (force) / (mass) .

OK.  We start out with a certain acceleration 'A₀'.  It's the result of
a certain force 'F₀' and a certain mass 'M₀'.  (I used the little subscripts " ₀ "
to show that these are the originals, before any changes.)

             Original acceleration = (Original force) / (original mass)

                              A₀             =          F₀            /        M₀ .

Now you want to triple the force and cut the mass in half: 

                     New acceleration  A₁ = (3 F₀) / (1/2 M₀) .

Divide each side by 3:           A₁ / 3  =  F₀ / (1/2 M₀) .

Multiply each side by  1/2 :   (1/2 A₁) / 3  =  F₀/M₀

                                                   A₁ / 6  =  F₀/M₀

Take a look at the right side of that equation . . .  F₀/M₀ .
That's just the original acceleration  A₀ .
So now, after the change, we have                 A₁ / 6  =  A₀ .

You asked "What is the new acceleration ?"
OK.  Multiply each side by  6  :                        A₁ = 6 A₀ .

Whatever the original acceleration was, the
new acceleration is 6 times as much.

If it was originally  2 m/s², then after the change, it becomes  (6 x 2)  =  12 m/s² .

Final answer:

Using Newton's second law of motion, if the net force on a sled is tripled and the mass halved, the new acceleration would be 12 m/s².

Explanation:

The subject of this question is derived from the principle of Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This can be represented as: F=ma (Force = mass * acceleration).

Given that the original acceleration 'a' is 2 m/s², the force 'F' acting on the sled can be calculated as F=ma. But since the net force is being tripled and the mass halved, the new force would be 3F, and the new mass would be m/2.

Now we need to determine the new acceleration, which can be calculated as a = F/m. Plugging in our new values, we get a = (3F)/(m/2). This equates to a = 6F/m. Since the original force is calculated as F=ma, we can substitute this in the above equation. Hence the new acceleration is 6*2 m/s² = 12 m/s².
