Answer:
Explanation:
The velocity of each ball after the collision can be determined using the law of conservation of momentum. The law of conservation of momentum states that the total momentum of an isolated system remains constant if no external forces are acting on the system. In this case, the two balls form an isolated system before and after the collision, so their total momentum must be conserved.
Let's call the velocity of the heavier ball after the collision "v". The total momentum before the collision is given by:
p_i = (0.600 kg)(4.00 m/s) + (1.00 kg)(-5.00 m/s) = -2.00 kg m/s
The total momentum after the collision is given by:
p_f = (0.600 kg)(v) + (1.00 kg)(-7.25 m/s) = 0.600 kg v - 7.25 kg m/s
Since the total momentum is conserved, we can set the initial momentum equal to the final momentum and solve for v:
p_i = p_f
-2.00 kg m/s = 0.600 kg v - 7.25 kg m/s
Adding 7.25 kg m/s to both sides and dividing both sides by 0.600 kg, we get:
v = (2.00 kg m/s + 7.25 kg m/s) / 0.600 kg = 9.25 m/s
So, the velocity of the heavier ball after the collision is 9.25 m/s.
Answer:
The velocity of the heavier ball after the collision is 3.05 m/s
Explanation:
This is an example of partially elastic collision. In a partially elastic collision, momentum is conserved and the objects move at different speeds. A portion of the initial kinetic energy is still retained by the colliding objects after the impact.
The conservation of momentum states that the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision.
The formula for momentum is
[tex]p=mv[/tex]
We can conclude that
[tex]m_1v_{1i} +m_2v_{2i}=m_1v_{1f} +m_2v_{2f}[/tex]
Let object 1 be the 0.600 kg ball.
Let object 2 be the 1.00 kg ball.
We are given
[tex]m_1=0.600\\v_{1i} =4.00\\m_2=1.00\\v_{2i} =5.00\\v_{1f} =7.25[/tex]
Inserting our given values into the equation gives us
[tex](0.600*4.00)+(1.00*5.00)=(0.600*7.25)+\left(1.00*v_{2f}\right)[/tex]
Lets solve for [tex]v_{2f}[/tex].
Evaluate each set of parenthesis.
[tex]2.4+(1.00*5.00)=(0.600*7.25)+\left(1.00*v_{2f}\right)[/tex]
[tex]2.4+5=(0.600*7.25)+\left(1.00*v_{2f}\right)[/tex]
[tex]2.4+5=4.35+\left(1.00*v_{2f}\right)[/tex]
Anything multiplied by 1 stays the same.
[tex]2.4+5=4.35+v_{2f}[/tex]
Add 2.4 and 5.
[tex]7.4=4.35+v_{2f}[/tex]
Subtract 4.35 from both sides of the equation.
[tex]3.05=v_{2f}[/tex]

According to the problem the Velocity amplitude (in/s-peak) is 1.827 in/s-peak.
What is Velocity amplitude?Velocity amplitude is the maximum speed at which a particle or object is traveling in a specific direction. It is a measure of the strength of the motion expressed in terms of the magnitude of the velocity. It can be determined by measuring the maximum value of the velocity vector over a given period of time. Velocity amplitude is an important concept in physics, as it allows for the calculation of the acceleration, momentum, and energy of a particle or object. It can also be used to determine the frequency of a periodic motion, such as the frequency of a wave or the frequency of oscillation.
The equation for converting displacement amplitude to velocity amplitude is:
Velocity amplitude (in/s-peak) = (2 x Displacement amplitude (mils-p-p)) / (π x Frequency (cpm))

The term which describes the increased soil erosion in the regions where sheep and cattle eat the grasses and reggianvorz is called overgrazing.
What is overgrazing ?Overgrazing happens when livestock and other grazers (such as wildlife) consume more plant biomass than the vegetation can replenish in a reasonable amount of time, exposing the soil and lowering the vegetation's potential for production.
The exposure of the soil might hasten the potential for processes of water and wind erosion, which can result in soil losses. Less water infiltration into the soil might result in slower plant growth due to accelerated erosion processes and soil compaction caused by grazing animals.
Because less plant biomass is accessible as litter due to ongoing overgrazing, less soil organic matter, nutrients, and biotic activity are added to the soil. This causes the soil structure to deteriorate, which lowers the soil's capacity to store water and raises the risk of erosion.
Therefore, the term describing the given action is overgrazing.

(Submit your answer in nanometers. Remember 1nm = 10-9 m)
The peak wavelength of light coming from a star with a temperature of 5300 K is 2.0 x 10⁻⁷ m.
What is wavelength?Wavelength is a measure of the distance between two consecutive wave crests or troughs and is usually defined as the length of one full cycle of a wave. Wavelengths are typically measured in meters, centimeters, or nanometers (10-9 meters). Wavelength is inversely related to frequency, meaning that higher frequency waves have shorter wavelengths.
The wavelength of each energy level can be calculated using the equation λ = hc/E, where h is Planck's constant, c is the speed of light, and E is the energy level in electron volts. Using this equation, the four wavelengths of the emission spectrum are calculated as follows:
0.0 eV = 0.0 m, 1.5 eV

Oil having a density of 930 kg/m^3 floats on water. A rectangular block of wood 4.17 cm high and with a density of 975 kg/m3 floats partly in the oil and partly in the water. The oil completely covers the block. How far below the interface between the two liquids is the bottom of the block?
Answer: 0.0268 m
Explanation:
Draw a free body diagram of the block. There are three forces: weight force mg pulling down, buoyancy of the oil B₁ pushing up, and buoyancy of the water B₂ pushing up.
Sum of forces in the y direction:
∑F = ma
B₁ + B₂ − mg = 0
ρ₁V₁g + ρ₂V₂g − mg = 0
ρ₁V₁ + ρ₂V₂ = m
ρ₁V₁ + ρ₂V₂ = ρV
ρ₁Ah₁ + ρ₂Ah₂ = ρAh
ρ₁h₁ + ρ₂h₂ = ρh
(930 kg/m³)h₁ + (1000 kg/m³)h₂ = (968 kg/m³) (4.93 cm)
Since the block is fully submerged, h₁ + h₂ = 4.93 cm.
(930 kg/m³) (4.93 cm − h₂) + (1000 kg/m³)h₂ = (968 kg/m³) (4.93 cm)
h₂ = 2.68 cm
h₂ = 0.0268 m
