The work done w in terms of K₁ is (9/16)K₁..Work done is equal to change in kinetic energy of the body.
Since, it is given a electron is moving with Kinetic energy. We know that kinetic energy of any moving body is given by=(1/2)mv²
where m is defined as the mass of the body
and v is defined as the velocity of the body.
Initially K₁.=(1/2)[tex]m_e[/tex]v²
=>v²=2 K₁ / [tex]m_e[/tex]
=>v=√(2 K₁ / [tex]m_e[/tex])--------(eq1)
Now,velocity of body becomes one plus one-fourth of the above velocity,so new velocity is =[√(2 K₁ / [tex]m_e[/tex]) + [(1/4)×√(2 K₁ / [tex]m_e[/tex])]=(5/4)×√(2 K₁ / [tex]m_e[/tex].
Therefore, we know that work done is equal to change in kinetic energy of the body
=>W=(1/2)×[tex]m_e[/tex]×(v₂²-v₁²)
=>W=(1/2)×[tex]m_e[/tex] × ([(5/4)²×√(2 K₁ / [tex]m_e[/tex].)²- (√(2 K₁ / [tex]m_e[/tex]))²]
=>W=(1/2)×[tex]m_e[/tex] ×[(25/16)-1]×(2 K₁ / [tex]m_e[/tex].)
=>W=((25-16)/16)×K₁
=>W=(9/16)×K₁
Hence, work done in terms of K₁ is (9/16)K₁.

MV = - ma×va + mb×vb ( we use negative sign because part a travels left)
Now, the initial velocity of parent nuclei is zero because it was at rest that is V = 0. So, the equation will be

a solid object is found to weigh 4.784.78n in air. when it is weighed while fully immersed in water, its apparent weight is 2.482.48n. what is the density of the object?
A solid object is found to weigh 4.784.78n in air. when it is weighed while fully immersed in water, its apparent weight is 2.482.48n. 983 is the density of the object.
The substance's density is defined as its mass per unit of volume (volumetric mass density or specific mass). Although the Latin letter D may also be used, the symbol for density that is most usually used is (the lower case Greek letter rho). where V is the volume, is the density, and m is the mass. Weight per unit volume is a common informal definition of density, however this is incorrect scientifically; the actual term is specific weight. The US oil and gas industry serves as one illustration of this. A pure substance's mass concentration in numbers is equal to its density. To make density comparisons between different systems of units easier, it is occasionally replaced by the dimensionless quantity "relative density" or "specific gravity," which is the ratio of the density of the material to that of a standard material, usually water. If a substance's relative density to water is less than one, it will float in it. Temperature and pressure have an impact on a substance's density. This variation is frequently not very noticeable for solids and liquids, but it is very noticeable for gases. As pressure is applied, an object's density rises, which reduces the object's volume. With a few rare exceptions, as temperature increases, a substance's density decreases as its volume grows.

The reaction force at Q is 4N.
A support reaction is a force on a support or a resulting restraining end moment, which results due to a prevented possibility to move. In the case of structural systems, support reactions are in equilibrium with the external forces acting on the structure.
The uniformly distributed load can be replaced by a concentrated load acting at the centre of gravity of the UDL. The total load on beam is the UDL multiplied by the length of the beam,

how does the kinetic energy gained by a charge relate to the potential across the plates of a capacitor?
The voltage supplied determines how strong the electrostatic force is inside a capacitor, and the length among the plates determines how weak it is.
The energy held in the capacitor stays unchanged as plates spacing increases, while capacitance falls. As a result, there is only a potential rise inside the differential here between plates.
By virtue of energy conservation, kinetic energy (KE) must be proportional to the change in potential energy (qV), either conversely. In terms of numbers, the voltage among the plates and the electron's energy in electron-volts are identical. For instance, a 5000-V voltage differential results in 5000-eV electrons. Energy in potential is position-dependent. To put it another way, it varies based here on weight and height of the object. The mass and initial velocity affect the kinetic energy of that object. When we consider a waterfall, we can see that the motionless liquid now at peak of something like the drop possesses potential energy.
The virial theory argued that kinetic energy is equivalent to half of potential energy's negative figure. The double of negative kinetic energy is called potential energy. The kinetic energy's opposite, amount of energy, is the same.

What is milky way Galaxy?The Milky Way is the galaxy that includes our Solar System, with the name describing the galaxy's appearance from Earth. A hazy band of light seen in the night sky formed from stars that cannot be individually distinguished by the eye.
Where is Earth in the Milky Way?Earth is located about halfway between the center of the Milky Way and its outer edge. Light at the galaxy's center takes 25,000 light-years to travel from Earth. A light-year is the distance light travels in one year.
There are around fifty galaxies in the Milky Way, the largest of which is the Large Magellanic Cloud. This satellite galaxy has a diameter of only 14,000 light-years. The Large Magellanic Cloud may have as many as 10 billion stars within it.

with respect to saving energy, what aspect of using two-sided printing was discussed in class as providing the most signifiant benefit?
The most significant benefit of using two-sided printing with respect to saving energy is that it reduces the amount of paper used.
When printing on both sides of a sheet of paper, the printer uses half as much paper as it would if it were only printing on one side. This means that less paper needs to be produced, which in turn reduces the amount of energy and resources used in the production and transportation of the paper. In addition, using less paper also reduces the amount of waste and pollution generated by the disposal of used paper.
While using two-sided printing may also reduce the amount of energy used by the printer itself.

which lists galaxy types in terms of star formation rate from making the most stars to making the fewest stars?
Lists galaxy types in terms of star formation rate from making the most stars to making the fewest stars
1. Starburst galaxies
2. Irregular galaxies
3. Spiral galaxies
4. Elliptical galaxies
1. Starburst galaxies: These galaxies have the highest star formation rate, making up to 1000 times more stars than the Milky Way. This is due to their high gas content, which allows them to form stars quickly.
2. Irregular galaxies: These galaxies have an intermediate star formation rate compared to other types of galaxies. This is because they have an irregular shape, which allows for different regions of gas to form stars at different rates.
3. Spirals galaxies: These galaxies have a moderate star formation rate, usually making up to 10 times more stars than the Milky Way. This is due to the presence of spiral arms, which direct gas towards the nucleus where it can form stars.
4. Elliptical galaxies: These galaxies have the lowest star formation rate, usually making up to 1/10th of the stars the Milky Way does. This is because they contain very little gas and dust, which are necessary for star formation.

in a particle system of smoke, which property is used to change the dense black, to semi-transparent gray and finally white?
In a particle system of smoke, color over Lifetime is used to change the dense black, to semi-transparent gray and finally white.
The Color over Lifetime module permits you to change the Color and Alpha qualities over time.
The Force over Lifetime module permits you to add wind-impacted articulations to Particles.
For instance, on the off chance that you set it as displayed in the picture, it will appear as though the breeze is blowing to one side.
The Limit Velocity over Lifetime module permits you to dial back the development of a molecule.
This permits you to execute articulations like air opposition.
In the Speed field of the Limit Velocity over Lifetime module, you can enter the speed that outcomes from the deceleration because of air opposition.
Dampen is the magnitude of the air resistance.
Set Start Speed to 20, Speed in the Limit Velocity over Lifetime module to 0, and Dampen to 0.1.
Assuming Hose is set to 0.1, the speed of 20 will continuously move toward 0 lastly stop.
