Which Period 3 element would you expect to have the highest electrical and
thermal conductivity?
A. Chlorine (CI)
B. Phosphorus (P)
C. Sulfur (S)
D. Sodium (Na)

Answers

Answer:

The correct option is D

Explanation:

Generally, thermal and electrical conductivity is affected by valence electrons in an atom. These valence electrons carry electric charges (or conduct heat as the case may be) throughout the atom. The fewer the valence electrons, the higher its conductivity - this is as a result of free movement within the atom. The higher the valence electrons, the lesser its conductivity and when the outermost electrons have completely filled the outermost shell, the atom would be an insulator as there won't be carriers of electric charges.

Hence, from the above, sodium would be expected to have the highest electrical and  thermal conductivity because it has just one electron in it's outermost shell

An autographed baseball rolls off of a 0.93 m high desk and strikes the floor 0.56 m away from the desk. How fast was it rolling on the desk before it fell? The acceleration of gravity is 9.81 m/s^2. Answer in units of m/s.

Answers

First of all, how long does it take it to fall 0.93m to the floor ?

Distance falling from rest = (1/2) · (g) · (T²)   <== memorize this formula

(0.93 m) = (1/2) (9.8m/s²) (T²)

Divide each side by (4.9 m/s²) :  T² = (0.93/4.9)  =  0.1898 s²

Square root each side:  T to hit the floor = 0.436 second

It got 0.56m away from the desk horizontally in 0.436 sec.

Speed = (distance) / (time)    <=== memorize this formula

Speed = (0.56 m) / (0.436 sec)

Speed = 1.28 m/s

NEED HELP!?Which of the following combinations would result in the greatest acceleration?

A 60N & 2.0kg
B 1N & 0.20kg
C 5N & 0.35 kg
D 12N and 1.0 kg

Answers

Answer:

The greatest acceleration is presented in option A 60N & 2.0kg

Explanation:

The second Newton's law relates the net force F exerted on an object of mass m and the acceleration it has by the equation:

F=m.a

The acceleration is found by solving the equation for a:

[tex]\displaystyle a=\frac{F}{m}[/tex]

Let's compare the different options and choose the greatest acceleration.

A F= 60 N, m= 2 Kg.

[tex]\displaystyle a=\frac{60}{2}=30\ m/s^2[/tex]

B F= 1 N, m= 0.20 Kg.

[tex]\displaystyle a=\frac{1}{0.2}=5\ m/s^2[/tex]

C F= 5 N, m= 0.35 Kg.

[tex]\displaystyle a=\frac{5}{0.35}=14.29\ m/s^2[/tex]

D F= 12 N, m= 1 Kg.

[tex]\displaystyle a=\frac{12}{1}=12\ m/s^2[/tex]

The greatest acceleration is presented in option A 60N & 2.0kg

At the top of a hill that is 4.37 meters high, a 70 kg skate boarder has 3000 1 point
joules of potential energy. What is his speed at the bottom of the hill where
his potential energy is zero?

Answers

Answer:

9.26m/s

Explanation:

Given parameters:

Height of the hill  = 4.37m

Mass of skate boarder = 70kg

Potential energy  = 3000J

Unknown:

Speed at the bottom of the hill  = ?

Solution:

At the bottom of the hill, the total potential energy is the same as the kinetic energy.

          Potential energy  = Kinetic energy

                  mgh  =  [tex]\frac{1}{2}[/tex]mv²  

                       2mgh  = mv²

                           v² = 2gh

                           v = √2gh

 g is the acceleration due to gravity

h is the height

                     v  = √2 x 9.8 x 4.37  = 9.26m/s

A chemical reaction [can/cannot] change an element into another element.

Answers

Depending on the context of your question: a chemical reaction can not! but Alpha decay is a kind of radioactive decay in which an alpha particle is emitted from an atom. An alpha particle consists of two protons and two neutrons. Therefore, when an atom of an element undergoes alpha decay, it loses two protons, which changes the atom from one element to another. This is because each different element is identified by the number of protons in its atomic nuclei.

A 438 gram ball is traveling east at 39 m/s when it is hit by a 2.4 kg softball bat. After being in contact with the bat for 302 ms, the ball rebounds at a speed of 28 m/s.
Determine the impulse vector (magnitude and direction) in kg*m's felt by the bat. Treat east as the positive direction.

Answers

Answer:

The magnitude of the impulse vector of the bat is 29.346 kg.m/s

The direction of the impulse vector of the bat is in the initial direction of the ball before impact

Explanation:

The given parameters are;

The mass of the ball, m₁ = 438 g

The speed of the ball = 39 m/s

The mass of the softball bat = 2.4 kg

The time of contact = 302 ms = 0.302 seconds

The speed of rebound = 28 m/s

The impulse = The change in momentum = Δp = F × Δt = m × Δv

The impulse on the ball = m₁ × Δv = 0.438 × (39 - (-28)) = 29.346 kg·m/s

Given that force of reaction of the bat is in opposite direction but equal to the force of the ball, and the time and the duration of contact with the ball is the same for both the ball and the bat, the impulse vector ore equal and opposite

Therefore, the magnitude of the impulse vector of the bat = 29.346 kg.m/s

The direction of the impulse vector of the bat = The initial direction of the ball before impact.

A peach has a layer of skin, a thick section of fruit, and a pit in the center. Which of these would a peach be a good model for?
A.

B.

C.

D.

Answers

Answer:

The earth

Explanation:

Answer:

D. the Earth

Explanation:

The Earth has a solid metal core at the center, which is similar to the pit of a peach. The Earth also has many thick layers of rock and liquid metal between the surface and the center of the Earth, similar to how a peach has a layer of skin and a thick section of fruit. The other answer choices don't have any similarities to a peach. The ocean is entirely liquid, the sun is a ball of gas, and the solar system contains lots of different planets and stars that all are made up of very different things.

Object X and object Y, of charge +Q and −2Q, respectively, are separated by a distance r0, as shown in the figure.

(a) Determine an equation for the magnitude and direction of the electric force that is exerted on object Y from object X in terms of Q, r0, and physical constants, as appropriate.

(b) The charge of object X is changed so that it has a charge of −4Q, and the separation distance between the two objects is changed to 2r0. In a clear, coherent paragraph-length response that may also contain figures and/or equations, predict how the electric force exerted on object Y from object X changes from part (a), and predict how the net charge of the two object system changes from part (a).

Answers

Answer:

(a) The magnitude of the force electric force F = k ×(+Q) × (-2·Q)/r₀² = -2·Q²/(r₀²) which can be written as follows;

[tex]F = \dfrac{k \times (+ Q) \times (-2\cdot Q)}{r_0^2} = -\dfrac{k \times 2 \times Q^2}{r_0^2}[/tex]

Given that the charge of Y is twice the charge on X, we have the charge X will move towards the charge Y which is the +x direction

(b) The force, F, acting between the charges is given as follows;

[tex]F = \dfrac{k \times Q_1 \times Q_2}{r_0^2}[/tex]

When, Q₁ = X = -4Q, Q₂ = Y = -2Q, and r₀ = 2·r₀ we have;

[tex]F = \dfrac{k \times (-4\cdot Q) \times (-2\cdot Q)}{(2 \cdot r_0)^2} = \dfrac{k \times 8 \times Q^2}{4 \cdot r_0^2} = \dfrac{k \times 2 \times Q^2}{r_0^2}[/tex]

Therefore, the electric force exerted on object Y by the object X is the same and acts in an opposite direction to the force of X on Y in (a)

The net charge of the two objects in part (a) is Q - 2Q = -Q

The net charge of the two objects in part (b) is -4Q - 2Q = -6Q

Therefore, the net charge increases by a factor of 6 in part (b)

F = 294 N
Answer M

The force used by the girl in pushing the box is 294 Newtons.

Hence, option M) 294N is the correct answer.

What is force?

Force is simply a push or pull capable of changing the state of rest or motion of an object.

From Newton's second law of Motion;

F = ma

Where m is mass of object and a is acceleration.

Given the data in the question;

Mass of box m = 42kgAcceleration a = 7m/s²Force applied F = ?

What is the electric force between them if the pieces of grain are 2 cm apart?

Answers

Answer:

F = 3.105 10⁻²⁰ N

Explanation:

For this exercise let's use Coulomb's law

          F = k q₁ q₂ / r²

in this case each of the grains has a charge

         q1 = 6.0 10⁻¹⁰ C

         q2 = 2.3 10⁻¹⁵ C

and they are separated by a distance r = 2 cm = 0.02 m

let's substitute

          F = 9 10⁹ 6.0 10⁻¹⁰ 2.3 10⁻¹⁵ / 0.02²

 

         F = 3.105 10⁻²⁰ N
