The rotational inertia of a meter stick, with mass 0.78 kg, about an axis perpendicular to the stick and located at the 17 cm mark is 0.136 kg m²
Since the stick can be treated as a thin rod, the center of mass of the stick will be at its midpoint which is 0.5 m.
L = 1 m
M = 0.78 kg
I at center of mass Icm = M L² / 12
Icm = 1 * 0.78² / 12
Icm = 0.051 kg m²
From the center the 17 cm mark will be at a distance of,
d = 0.5 - 0.17
d = 0.33 m
I = Icm + M d²
I = 0.051 + ( 0.78 * 0.33² )
I = 0.051 + 0.085
I = 0.136 kg m²
Therefore, the rotational inertia is 0.136 kg m²

The fraction is f = 84.196 % which is equivalent to 84%
We know that the value of acceleration due to gravity is
g = 9.8m/s^2
y₀ = 1 m
x = 10 m
and the time taken is not given
thus time taken = t sec
A₀ = π 1.5²
Thus the equation becomes;
y = y₀ + ut + 1/2 gt²
⇒ 0 = y₀ - 1/2 gt²
⇒ t = [tex]\sqrt{\frac{2y.}{g} }[/tex]
After substituting the values we get
⇒ t = 0.45152 seconds
Thus x = x₀ + vt
10 = 0 + 0.45152 v
On further solving we get
v = 22.14741 m/s
From continuity equation we get
Av = A₀v₀
On substituting the values we get

Despite being two distinct ideas, phenotype and genotype are tightly intertwined. The term "phenotype" describes the physical characteristics of an organism that result from the expression of a person's genes.
The phenotype of an individual is determined by genotype. While an organism's genotype refers to its genetic makeup, its phenotype describes how it looks on the outside. The visible manifestation of a person's genes is their phenotype. Therefore, even an organism belonging to the same species may vary due to a slight variation in their genotype. The primary distinction between the two is this.
Their genotype could be used to decipher the human genetic code. It chooses which features or qualities to display. Even organisms with the same genotype might have different appearances. Periodically, both behavior and appearance change. In contrast, even identical-looking species do not share the same genotype.

The horizontal component is 0.72 N to the right.
How is force and friction related ?The amount of static friction is inversely proportional to the amount of normal force and the degree of roughness between the sliding surfaces. The friction coefficient is calculated by dividing the frictional force's magnitude by the force's normal force.
The applied force must be greater than the friction force since the net force is to the right (in the direction of the applied force). Understanding net force as the vector sum of all the forces can help you calculate the friction force.
Given , F = 1.2 N and mass = 1 kg
we will you F - цN = ma ------- 1
and equate it with the equation ma = mg + N
After substituting the values
We will get the value of acceleration as 0.4 [tex]m/s^2[/tex]
Substitute this value in equation 1
and we will get ц = 0.72 N

Migration of the electron between xi = L towards xf = 3L based on the supplied statement.
What does force signify in science?In science, the term "force" has a particular definition. At this point, it is quite acceptable to refer to a force as a push or possibly a pull. There is no such thing as a charge that an instrument "seems to have in it" or "contains." The idea of a force encompasses both living and non-living things.
What causes the balancing force?One definition of equilibrium is a state of equilibrium forces. Because when forces are in equilibrium, there is no direction change. The sum of balanced forces is always equal to zero.

What is a binary star system?Basically, a star means giant astronomical or celestial object that contains a luminous sphere of plasma and bounded together by its own gravitational force. A binary star system refers to a star system that typically comprises two stars that includes a brighter star and dimmer star.
The dimmer star are easily detectable by astronomers because its gravity causes the bright star to wobble and can be spotted by astronomers through an observation of a phenomenon that is referred to as an eclipsing binary.

a certain amount of nobr(g) is sealed in a flask, and the temperature is raised to 350 k. the following equilibrium is established: nobr(g) uv no(g) 1 12 br2(g) the total pressure in the flask when equilibrium is reached at this temperature is 0.675 atm, and the vapor density is
The partial pressures of each species of the equilibrium are
NOBr = 0.39 atmNO = 0.19 atmVapour density = 2.219 g / L
Temperature = 350 K
Total pressure = 0.675 atm
Since volume of flask is constant and the mass is conserved,
Initial mass of NOBr = 2.219 g
1 mol NOBr = 109.92 g
Number of moles of NOBr = 2.219 / 109.92 = 0.02019 mol
Total number of moles at equilibrium is,
[tex]n_{total}[/tex] = ( 0.02019 - x ) + x + 0.5 x
[tex]n_{total}[/tex] = 0.02019 + 0.5 x
Acording to ideal gas equation.
[tex]n_{total}[/tex] = P V / R T
[tex]n_{total}[/tex] = ( 0.675 * 1 ) / ( 0.08206 * 350 )
[tex]n_{total}[/tex] = 0.00662
Partial pressure of NOBr,
P = ( 0.02019 - x ) * 0.675 / ( 0.02019 + 0.5 x )
P = 0.39 atm
Partial pressure of NO,
P = x * 0.675 / ( 0.02019 + 0.5 x )
P = 0.19 atm
Partial pressure of Br₂,
P = 0.5 x * 0.675 / ( 0.02019 + 0.5 x )
P = 0.095 atm
Therefore, the partial pressures of

Assuming that the satellites do not affect each other, find the orbital periods t1 and t2 of the two small satellites without using the mass of pluto.
The orbital periods of the two small satellites are [tex]T_{sat1} = 24.5 days[/tex] and [tex]T_{sat2} = 37.7 days[/tex].
What is orbital periods?An orbital period is the time it takes for a given astronomical object to orbit another object. In astronomy, it usually applies to planets or asteroids orbiting the sun, moons orbiting planets, exoplanets orbiting other stars, or binary stars. Changes in the orbital period can be explained by the evolution of the mass asymmetry to symmetry (symmetry of the binary system). Decreasing and increasing orbital periods are predicted to be related to the non-overlap and overlap of the binary in its symmetrisation respectively. Orbital decay is the gradual decrease in the distance between two orbiting bodies at their point of closest approach over several orbital periods. These orbiting bodies can be a planet and its satellite, a star and any object orbiting it, or parts of some binary system.Therefore,
distance of first satellite = 48,000 Km
distance of second satellite = 64,000 Km
orbital period = 6.39 day
Using equation of time period
[tex]T =\frac{ 2\pi r^{3^{/2} } \\}{\sqrt{GM_{pluto} } }[/tex]
now, from the above equation we can say that only variable is Time period and r is the radii of orbit.
from the first satellite
[tex]\frac{T _{charon} }{r^{\frac{3}{2}_{charon} } }[/tex][tex]= \frac{Tsat_{1} }{r^{\frac{3}{2}_{sat1} } }[/tex]
[tex]T_{sat1} = \frac{T_{charon}r^{\frac{3}{2} } }{r^{\frac{3}{2} _{charon} } }[/tex]
[tex]T_{sat1} = \frac{6.39\times48000^{\frac{3}{2} } }{19600^{\frac{3}{2} } }[/tex]
[tex]T_{sat1} = 24.5 days[/tex]
for 2nd satellite,
