To bring heavy boxes down a flight of stairs, Tyrone uses a ramp. He slides the boxes down the ramp. The movement transforms one type of energy into two other forms. Which of the following describes the way that most of the energy is transformed:

ANSWER:

Potential energy into heat and kinetic energy

Explanation:

According to this question, a ramp is used to bring heavy boxes down a flight of stairs. Tyrone does this by sliding the boxes down the ramp. The ramp is in a fixed position i.e. not moving, meaning the energy in the ramp is POTENTIAL ENERGY.

However, when the boxes slide down the ramp, the potential energy transforms to energy due to motion called KINETIC ENERGY, and HEAT ENERGY, which is caused by the friction between the boxes and the ramp.

Therefore, the potential energy of the ramp is transformed to kinetic energy in the boxes and heat energy.

Answer:

F₂ = 3.97 F₁

Hence, the force will be increased by a factor of 3.97

Explanation:

The force between the ball and the bowling pin is given by Newton's Gravitational Law, as follows:

F = Gm₁m₂/r²

where,

F = Force

G = Gravitational Constant

m₁ = mass of ball

m₂ = mass of bowling pin

r = distance between ball and bowling pin

So, initially:

F₁ = G(3.6 kg)(1.36 kg)/r²

F₁ = 4.896 G/r²

After increase in masses:

F₂ = G(7.2 kg)(2.7 kg)/r²

F₂ = 19.44 G/r²

F₂/F₁ = (19.44 Gr²)/(4.896 G/r²)

F₂ = 3.97 F₁

Hence, the force will be increased by a factor of 3.97

Answer: analyze the question so that you can get a correct answer

Explanation:

Answer:

D

Explanation:

More protons in the nucleus pull the electrons in, making the atomic radius smaller. Therefore, the correct option is option D.

The atomic radius is determined by the nucleus's balance between the attracting force of positively charged protons and the repelling force of electrons.

The most crucial element in calculating the average atomic radius is not Option A. Although atomic mass typically increases with time, increasing nuclear charge has a greater impact on atomic size.

Over time, Option B has no discernible impact on atomic radius. Although the number of valence electrons changes over time, increasing nuclear charge has the biggest impact on atomic size. The valence shell is the outermost electron shell.

The gradual decrease in atomic radius is unaffected by Option C. The most frequent electron pairing occurs within orbitals of the same energy level, and it has little impact on atomic size over a period.

Therefore, the correct option is option D.

Answer:

C-

Ionic

Explanation:

Just did the quiz

The bonding occurs between the valence electron of an atom. The ionic bond involves the transfer of electrons between atoms. Thus, option c is correct.

A chemical bond that involves the complete transfer of electron/s from one element to another in a molecule or compound is an ionic bond.

The ionic bonds comprise cations that gave the electron to another element called the anion that gained or accepted the electron. This results in an attractive force between them to form a bond.

The positive and negative charges attract one another which leads to the formation of the ionic bond. The most common example is NaCl in which sodium has a positive and chloride has a negative charge.

Therefore, option c. ionic bond involves the transfer of electrons.

Answer:

An electromagnet is a coil of wire wrapped around a bar of iron or other ferromagnetic material. When electric current flows through the wire, it causes the coil and iron bar to become magnetized. An electromagnet has north and south magnetic poles and a magnetic field.

Explanation:

The three main components of an electromagnet are the iron core, copper wire, and an electricity source.

An electromagnet is a magnet in which a coiled or wrapped wire is given electricity. When Current is given to this wire, it acts like a magnet. An electromagnet is used to create a magnetic field.

The three main parts of the electromagnet are the iron core, that is the magnet, which is a small round, or square brick-like. The wire, wire, is made up of copper. The electricity source, by which electricity is given to the electromagnet.

Examples of electromagnets are induction cookers, doorbell rings, etc. They are controllable and adjustable magnets and are used in most electric appliances.

Thus, the three parts are the iron core, copper wire, and an electricity source.

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume}\\[/tex]

From the question

mass = 8.32 g

volume = 4.3 mL

So we have

[tex]density = \frac{8.32}{4.3} \\ = 1.934883720...[/tex]

Hope this helps you

Answer:

A

Explanation:

I think...........maybe

Answer:

yes

Explanation:

Given parameters:

Density of table salt = 2.16g/cm³

Mass of table salt  = 4.25kg = [tex]\frac{0.00425}{2.16}[/tex][tex]\frac{0.00425}{2.16}[/tex]g (1000g = 1kg)

Unknown:

Volume of table salt = ?

Solution:

To find the volume of the table salt, let us state the relationship between density, mass and volume.

 Density is the mass per unit volume of substance.

           Density  = [tex]\frac{mass}{volume}[/tex]  

Since the unknown is volume;

      Density x volume  = mass

                    Volume  = [tex]\frac{mass}{density}[/tex]

Input the parameters and solve';

                  Volume  = [tex]\frac{0.000425}{2.16}[/tex]  = 1.97 x 10⁻³cm³

Volume of the table salt is  1.97 x 10⁻³cm³

I am not quite sure if this is what you are looking for but each side of the equation should be equivalent.

Answer:

Net force= 0N or 0units

Object is balanced

Explanation:

Net force refers to all the sum total of all forces acting upon an object. In this case, a boy and a girl are pulling a heavy crate at the same time with 7 units of force each.

- This means that the force exerted on the crate by the boy is F1 = 7units

- The force exerted on the crate by the girl is F2 = -7units

Hence, the Fnet = F1 + F2

Fnet = 7 + (-7)

Fnet = 0 units

An object which possess a net force is said to be unbalanced, while an object with no net force i.e 0 units or N. Hence, the heavy crate in this case being pulled by a net force of 0units is BALANCED.

The force applied on the object is a balanced force since the object is at equilibrium.

The given parameters;

force applied by the boy, F₁ = 7 N

force applied by the girl, F₂ = 7 N

The net force on the object is the resultant of the two equal both opposite directed force.

Let the boy's direction be positive

Let the girl's direction be negative

The resultant of the two forces is calculated as;

[tex]\Sigma F_x = F_1 + F_2\\\\\Sigma F_x = (7 \ N) + (-7 \ N)\\\\\Sigma F_x = 0[/tex]

Thus, the force applied on the object is a balanced force since the object is at equilibrium.
