The moment of inertia of the boxer's forearm will be 0.525kg.[tex]m^{2}[/tex]
In physics, it means quantitative measure of the rotational inertia of the body. As an example, the opposition that the body exhibits to having its speed of rotation about an axis altered by the application of a torque (turning force). The axis may be internal or external and may or may not be fixed.
From the question given, the triceps muscle in the back of the upper arm extends the forearm of a professional boxer when he extends his arm,
Torque generated due to this force is,
τ = F * r
τ = torque is generated
F = force exerted = 2903n
r = the radius of the lever arm = 2.35cm = 0.0235m
Now let's use the torque formula
τ = 2903N * 0.0235m
τ = 68.2205 N.m
Next, we want to find the moment of inertia of the boxer's forearm by calculating the relation between torque and moment of inertia and angular acceleration,
τ = torque = 68.2205Nm
I = moment of inertia
α = angular acceleration = 130 rad / s²
τ = Iα
68.2205 = I*130rad/s²
I = 0.525 kg.m² (rounded)
Therefore, the value of moment of inertia is 0.525kg.m²

. suppose that the central diffraction envelope of a double-slit diffraction pattern contains 11 bright fringes and the first diffraction minima eliminate (are coincident with) bright fringes. how many bright fringes lie between the first and second minima of the diffraction envelope?
7 bright fringes lie between the first and second minima of the diffraction envelope.
Diffraction is defined because of the interference or bending of waves around the corners of an obstacle or via an aperture into the vicinity of the geometrical shadow of the impediment/aperture. The diffracting object or aperture correctly becomes a secondary source of the propagating wave.
Refraction is the alternate in direction of waves that takes place whilst waves journey from one medium to another. Refraction is always accompanied by means of a wavelength and speed alternate. Diffraction is the bending of waves around barriers and openings. the amount of diffraction increases with increasing wavelength.
Calculation:-
Here d = 15 a/2(since there are 15 bright fringes ).
Then for the first minimum which occurs at an angle1
then a sin? 1 =? (m=1)
For the second minimum which occurs at an angle= of 2
then a sin?2 = 2? (m=2)
then we calculate the values of m for which

a ball is kicked with an initial velocity of 23 m/s in the horizontal direction and 14 m/s in the vertical direction. (assume the ball is kicked from the ground. for each answer, enter a number.) (a) at what speed (in m/s) does the ball hit the ground? m/s (b) for how long (in s) does the ball remain in the air? s (c) what maximum height (in m) is attained by the ball?
The speed of the ball is 192m/s. The long of the ball is 2.85s.The height of the ball is 2.13m.
How to calculate speed?A)The speeds at these points are equal since the starting position and the point at which it touches the ground have the same elevation. Solving the product of the horizontal and vertical velocities yields the final speed. Which is
vf=√(V[tex]ox[/tex])²+(V[tex]oy[/tex])²
vf=√(23m/s)²+(14m/s)²
vf=192m/s
How to calculate long?B)Take into account the starting point and the highest point, respectively.
We are aware that the vertical velocity is zero at the highest point. Additionally, we are aware that the duration of the flight from start to finish is twice as long.
So, we'll apply the formula t=v[tex]f[/tex]-v[tex]o[/tex]/a
t=2(v[tex]top[/tex]-v[tex]o[/tex])/a
t=2(0m/s-14m/s)/-9.81m/s

a baseball and a bowling ball with the same momentum are rolling toward you. which one needs more efforts (either longer time or larger force) to be stopped?
The baseball will require longer time and the bowling ball will require more effort to be stopped.
The bowling ball and baseball is moving with same momentum.
Let us say the momentum of the bowling ball is MV and the momentum of the baseball is mv.
According to second law of newton,
F = ΔMV/Δt
F = MΔv/Δt
So, the force is directly proportional to the speed of the object.
The speed of the bowling ball will be less than that of the baseball because the mass of the bowling ball is more and the mass of the baseball is less.
So, a greater force will be required to stop the baseball ball,
F = mΔv/Δt
v is more and the contact period Δt of the transfer of momentum is less so baseball will require longer time and a grater force will be required to stop the bowling ball because the speed is less.

a bullet fired from a rifle begins to fall when?
Answer: As soon as it leaves the barrel.
Explanation:
A bullet fired from a rifle begins to fall immediately upon leaving the barrel. Despite its initial forward momentum, the bullet is subject to the force of gravity.
The gravitational force acts vertically downward and causes the bullet to accelerate downward due to its free fall. However, due to its initial high velocity, the bullet's downward acceleration is minimal compared to its forward motion. As a result, the bullet follows a curved trajectory known as a ballistic trajectory.
Over time, the effects of gravity become more significant, causing the bullet to gradually descend and eventually hit the ground, following a parabolic path.

An inelastic collision between two objects is characterized by the fact that a) the total momentum of the system is conserved. Choice A is correct
Inelastic collisions are the collisions in which the kinetic energy is lost. The momentum of the system is conserved in inelastic collisions, but kinetic energy is not. This is because some of the kinetic energy was transferred to another.
Suppose two similar cars are approaching. They collide, but the sled is equipped with a magnetic clutch so that when they collide they combine into a single agglomerate.

The needed force approaches the real weight closer with a greater slope or gradient.
m = 5000 kg
F =force by air
Diameter of circle
D = 1000m
R = D/₂ = radius of circle
Fcosθ =mg----1
Fsinθ = mw² R
Fsinθ = mw² R---2
from 1 and 2 ( divide 2 by 1)
tanθ = w² R/g = 4 πR/T²g
tanθ = 4 π 500/30²×9.8
tanθ = 29.236
θ = tan⁻¹(29.236) = 65.9°.

how would stellar parallax observed from saturn differ from the stellar parallax we observe from earth?
Saturn is undergoing an apparent retrograde movement period as the Earth moves closer to Saturn in its orbit and then both planets are located on the side of the Sun. Stars that are nearer to us will exhibit higher parallax, similar to how it occurs on Earth.
The star parallax of the Earth is quite modest, barely 0.03 seconds of arc. It would be difficult to see against the backdrop of stars, even with a good telescope.
The angle between the Earth's place at a single time of year and the Earth 6 months later, as determined from a nearby star, is known as the parallax angle. This angle is used by astronomers to calculate how far away that star is from Earth.
We may calculate the distance to a nearby planet using the method described before, s. Now, measuring from an observation point O, we determine the angle the planet occupies, which is. Therefore, P1P2=d, where d is the planet's diameter. As a result, we may use the parallax method to calculate the radius of a neighboring planet.

Option a is correct
Who are people when they are hypnotized?Although hypnosis is frequently described as a sleep-like condition, it is actually better described as a state of sharpened focus, increased suggestibility, and vivid fantasies. People who are hypnotized frequently appear tired and disoriented, yet they are actually hyperaware.
What transpires while a person is tranced?Our brain waves must slow down in order to enter a trance. Throughout the course of the day, people alternate between several brain wave states. Different stages of the brain wave include sleeping, daydreaming, and being fully alert and focused.
