The way in which one atom interacts with another atom is mostly influenced by the configuration of the electrons farthest from the nucleus.

Option A.

An atom can be defined as the smallest part of a substance that cannot be broken down chemically. Each atom has a nucleus (center) made up of protons (positive particles) and neutrons (particles with no charge).

The arrangement of electrons in orbitals and shells around the nucleus is referred to as the electronic configuration of the atom.

Thus, we can conclude that the way in which one atom interacts with another atom is mostly influenced by the configuration of the electrons farthest from the nucleus.

Answer:

ΔP.E = - 588 J

Explanation:

The complete question is as follows:

It is said that Galileo dropped objects off the Leaning Tower of Pisa to determine whether heavy or light objects fall faster. If Galileo had dropped a 5.0-kg cannon ball to the ground from a height of 12 m, what would have been the change in PE of the cannon ball?

Answer: So, in order to calculate the change in Potential Energy of the cannon ball, we will use the general formula of Potential Energy as follows:

ΔP.E = mgΔh

where,

ΔP.E = Change in Potential Energy = ?

m = mass of cannon ball = 5 kg

g = acceleration due to gravity = 9.8 m/s²

Δh = Change in Height of Cannon Ball = Final Height - Initial Height

Δh = 0 m - 12 m = - 12 m

Therefore,

ΔP.E = (5 kg)(9.8 m/s²)(- 12 m)

ΔP.E = - 588 J

Negative sign shows decrease in Potential Energy

Answer: thunderstorm

Explanation:

When the sea surface is at least 80° Fahrenheit (27° Celsius), it can supercharge a thunderstorm. The storm sucks up that heat and water, which make the storm bigger. As it grows, air pressure at the center of the storm continues to drop, which causes the vacuum in the middle to grow stronger.

Answer:

The answer will be it has a mass of 40 kg.

Explanation:

Because Force = mass x acceleration or F = m a, we can say Force divided by mass or F/a = m or mass so 600 divided by 15 equals 40 kg.

- The resistance of the first resistor (R₁) is 12 Ω.

- The electromotive force (EMF) of the battery is 18 V.

- The internal resistance of the battery is 12 Ω.

To solve the given problem, we can apply Kirchhoff's laws and Ohm's law to determine the resistance of the first resistor (R₁) and the electromotive force (EMF) and internal resistance of the battery.

Let's start by calculating the resistance of the first resistor (R₁):

1. Apply Ohm's law to find the voltage drop across the external circuit:

  V = I * R

  V = 1 A * 6 Ω

  V = 6 V

2. The voltage drop across the external circuit is equal to the EMF minus the voltage drop across the internal resistance of the battery:

  V = E - Ir

  6 V = E - (1 A * r)   (where r is the internal resistance of the battery)

3. We also know that the EMF of the battery is the sum of the voltage drops across each cell in the battery:

  E = 6 cells * 3 V/cell

  E = 18 V

4. Substitute the value of E in the equation from step 2:

  6 V = 18 V - r

  r = 12 Ω

Therefore, the resistance of the first resistor (R₁) is 12 Ω.

The battery would have to supply 7.00 μC of charge to the capacitor.

The energy stored in the capacitor in this case is 7.98 μJ.

The battery would have to supply 4.05 mC of charge to store 1.30 J of energy in the capacitor.

The potential difference across the capacitor would be 20.2 V.

The charge supplied by the battery can be calculated using the formula Q = CV,

where Q is the charge, C is the capacitance, and V is the potential difference.

Thus,

Q = (5.00 μF)(1.40 V)

Q = 7.00 μC.

The energy stored in a capacitor can be calculated using the formula:

E = 1/2 CV^2,

where E is the energy, C is the capacitance, and V is the potential difference.

Thus,

E = 1/2 (5.00 μF)(1.40 V)^2

E = 7.98 μJ.

The charge required to store a certain amount of energy in a capacitor can be calculated using the formula:

Q = √(2CE),

where Q is the charge, C is the capacitance, and E is the energy.

Thus,

Q = √(2(5.00 μF)(1.30 J))

Q  = 4.05 mC.

The potential difference across a capacitor can be calculated using the formula V = √(2E/C), where V is the potential difference, C is the capacitance, and E is the energy.

Thus, V = √(2(1.30 J)/(5.00 μF))

V = 20.2 V

Explanation:

When you start pushing or pulling a stationary object with a constant force, it starts to move if the force you exert is greater than the net forces resisting the movement, such as friction and gravity. If the object starts to move at some speed, it will acquire kinetic energy. Kinetic energy is the energy an object has because of its motion.

Kinetic energy is the force that moves an object. If we want to accelerate something, we must apply a force.

Energy can take on a variety of shapes. Examples of these include: electric power, sound energy, energy source, nuclear and atomic energy, radiant energy, generate heat, mechanical energy, gravity, and so on. Each form has the ability to shift or transform into the others.

The term "energy" was initially employed in the realm of physics by Thomas Young (1773–1829), but it didn't catch on. Thomas Young later utilized interference experiments to demonstrate that light is a wave.

A 66.1-kg boy is surfing and catches a wave which gives him an initial speed of 1.60 m/s. He then drops through a height of 1.59 m, and ends with a speed of 8.51 m/s. The nonconservative work done on the boy is approximately -42.7 kilojoules.

To find the nonconservative work done on the boy, we need to consider the change in the boy's mechanical energy during the process. Mechanical energy is the sum of the boy's kinetic energy (KE) and gravitational potential energy (PE).

The initial mechanical energy of the boy is given by the sum of his kinetic energy and potential energy when he catches the wave:

E_initial = KE_initial + PE_initial

The final mechanical energy of the boy is given by the sum of his kinetic energy and potential energy after he drops through the height:

E_final = KE_final + PE_final

The nonconservative work done on the boy is equal to the change in mechanical energy:

Work_nonconservative = E_final - E_initial

Let's calculate each term:

KE_initial = (1/2) * m * v_initial^2

= (1/2) * 66.1 kg * (1.60 m/s)^2

PE_initial = m * g * h_initial

= 66.1 kg * 9.8 m/s^2 * 1.59 m

KE_final = (1/2) * m * v_final^2

= (1/2) * 66.1 kg * (8.51 m/s)^2

PE_final = m * g * h_final

= 66.1 kg * 9.8 m/s^2 * 0

Since the boy ends at ground level, the final potential energy is zero.

Substituting the values into the equation for nonconservative work:

Work_nonconservative = (KE_final + PE_final) - (KE_initial + PE_initial)

Simplifying:

Work_nonconservative = KE_final - KE_initial - PE_initial

Calculating the values:

KE_initial = (1/2) * 66.1 kg * (1.60 m/s)^2

PE_initial = 66.1 kg * 9.8 m/s^2 * 1.59 m

KE_final = (1/2) * 66.1 kg * (8.51 m/s)^2

Substituting the values:

Work_nonconservative = [(1/2) * 66.1 kg * (8.51 m/s)^2] - [(1/2) * 66.1 kg * (1.60 m/s)^2 - 66.1 kg * 9.8 m/s^2 * 1.59 m]

Calculating the result:

Work_nonconservative ≈ -42.7 kJ

Therefore, the nonconservative work done on the boy is approximately -42.7 kilojoules. The negative sign indicates that work is done on the boy, meaning that energy is transferred away from the boy during the process.

This question involves the concepts of density and mass.

The mass of water, displaced is "B. 20 g".

First, we will find out the volume of the woodblock by using the density of wood:

\(\rho_{wood} =\frac{m}{V}\)

where,

Therefore,

\(1\ g/cm^3 = \frac{20\ g}{V}\\\\V=\frac{20\ g}{1\ g/cm^3}\)

V = 20 cm³

Now, this is the same volume as the volume of water displaced by this block of wood. Hence, using the density of water, w can find the mass of water displaced:

\(\rho_{water}=\frac{m}{V}\\\\\rho_{water}(V)=m\\m= (1\ g/cm^3)(20\ cm^3)\)

Explanation:

The potential energy of the roller coaster is 176,400 J (joules).

The potential energy of an object is given by the formula PE = mgh, where PE is the potential energy, m is the mass of the object, g is the acceleration due to gravity, and h is the height or vertical position of the object.

In this case, the roller coaster is at a peak of 20m and has a mass of 900kg. The acceleration due to gravity, g, is approximately 9.8 \(m/s^2\).

Using the formula, we can calculate the potential energy:

PE = mgh

= (900 kg)(9.8 \(m/s^2\))(20 m)

= 176,400 J
