Force multiplied by distance is nothing but work done. It can also be described as work done is the dot product of force and distance.
A force is a quantity which is a vector because it has both a magnitude and a direction. According to Newton's laws, the force acting on an item is what causes it to move or cease moving.
Force multiplied by distance equals work. Work is a form of energy that is expended as an object moves along certain distance. However, note that this particular formulation:
W = F d
The above equation works only if force is constant and if the movement is entirely linear on a flat surface. General formula for determining work can be done through calculus as:
W = ∫ F ds
where the distance becomes differential from d to ds, and allows us to evaluate the work done even for non-linear paths or on paths that are inclined at angles above the horizontal plane.

what year was pluto reclassified as a dwarf planet
Pluto was downgraded to a dwarf planet by the International Astronomical Union (IAU) in 2006 because it failed to meet the three requirements for the definition of a full-sized planet.
Who originally demoted Pluto?
In a decision to more narrowly define a planet on August 24, 2006, the International Astronomical Union downgraded Pluto from the ninth planet from the sun to a dwarf planet, igniting a scientific and cultural debate.
Pluto was demoted in 2006; why?
Pluto is presently regarded as a dwarf planet because, while being huge enough to have grown spherical, it lacks the power to dominate its orbit and clear the area around it.

Answer:
2006
Explanation:
A worker drives a 0.5 kg spike into a rail tie with a 2.5 kg
sledgehammer. The hammer hits the spike with a speed of 65 m/s.
If 1/3 of the hammer's kinetic energy is converted into internal
energy, how much does the total energy increase?
The increase in internal energy will be 1760.42 J.
What is kinetic energy?kinetic energy is the energy of motion, observable as the movement of an object or subatomic particle. Every moving object and particle have kinetic energy. A person walking, a soaring baseball, a crumb falling from a table and a charged particle in an electric field are all examples of kinetic energy at work.The energy of a body due to its motion is called kinetic energy. - Every object around us which is moving possesses kinetic energy.Kinetic energy (KE) is the energy of a body in motion, which means it's essentially the energy of all moving objects. It is one of the two main forms of energy, along with potential energy, which is the stored energy contained within objects at rest.To learn more about kinetic energy refers to:

The table shows the relative atomic masses of some common elements. Use it to calculate the relative formula mass of sodium hydroxide, naoh.
Answer Relative Atomic Mass is - 39. 99
What is Relative Mass ?
-- Relative atomic mass, also known by the deprecated synonym atomic weight, is a dimensionless physical quantity defined as the ratio of the average mass of atoms of a chemical element in a given sample to the atomic mass constant.
-- The atomic mass constant is defined as being 1/12 of the mass of a carbon-12 atom
What is Molar mass
-- The mass of mole of a substance is called its molar mass.
What Is absolute mass ?
-- The absolute mass of an electron is, however, 9 x 10-28 gram.
-- The electron in an atom possesses a certain amount of energy to maintain its distance from the oppositely charged nucleus.
-- Without this energy, the electron would collapse into the nucleus.

Does more bandwidth reduce latency?.
Yes, more bandwidth reduce latency.
Bandwidth reduces latency because there is a wider pipeline through which more data passes, reducing the chance of data packets being delayed. On the other hand, high latency can create bottlenecks and reduce effective bandwidth, at least until the delayed data packets get through.
Maximum amount of data sent over an Internet connection in a given period of time. Bandwidth is often confused with internet speed. It is actually the amount of information that can be transmitted over a connection in a given amount of time, calculated in megabits per second (Mbps) or wireless communication links for transmitting data over network connections. The period specified for the transfer. Bandwidth is usually expressed in the number of bits, kilobits, megabits, or gigabits that can be transmitted per second.
