Explanation:La ecuación de Van der Waals es una ecuación de estado de un fluido compuesto de partículas con un tamaño no despreciable y con fuerzas intermoleculares, como las fuerzas de Van der Waals. La ecuación, cuyo origen se remonta a 1873, debe su nombre a Johannes van der Waals, quien recibió el premio Nobel en 1910 por su trabajo en la ecuación de estado para gases y líquidos, la cual está basada en una modificación de la ley de los gases ideales para que se aproxime de manera más precisa al comportamiento de los gases reales al tener en cuenta su tamaño no nulo y la atracción entre sus partículas.

Which is a measure of force? A. distance B. mass C. volume D. weight
Answer:
B. Mass
Explanation:
mass Includes newton which is a measure of force
weight is a measure of force. hence option D is correct.
What is Force ?Force is responsible for the motion of an object. it produces acceleration in the body. According to newton's second law force is mass times acceleration i.e. F =ma. Its SI unit is N which is equivalent to kg.m/s². There are two types of forces, balanced force and unbalanced force. Balanced forces are those forces which are opposite in direction and equal in magnitude. When Net force acting on a body is zero then we call it as balanced force. Balanced force is not responsible for the motion of the body. ex. when two persons pulling rope on both end with equal magnitude which cause them to be balanced force have 0 net force. Unbalanced forces are those when resultant of all the forces is not equal to zero is called as unbalanced force. unbalanced force is responsible for the motion of the body.

give some practical application of center of mass
Answer:
The center of mass of the human body depends on the gender and the position of the limbs. In a standing posture, it is typically about 10 cm lower than the navel, near the top of the hip bones. In this Atom, we will learn how to measure the COM of a human body.
Explanation:
In physics, the center of mass of a distribution of mass in space is the unique point where the weighted relative position of the distributed mass sums to zero. This is the point to which a force may be applied to cause a linear acceleration without an angular acceleration. Calculations in mechanics are often simplified when formulated with respect to the center of mass. It is a hypothetical point where entire mass of an object may be assumed to be concentrated to visualise its motion. In other words, the center of mass is the particle equivalent of a given object for application of Newton's laws of motion.
In the case of a single rigid body, the center of mass is fixed in relation to the body, and if the body has uniform density, it will be located at the centroid. The center of mass may be located outside the physical body, as is sometimes the case for hollow or open-shaped objects, such as a horseshoe. In the case of a distribution of separate bodies, such as the planets of the Solar System, the center of mass may not correspond to the position of any individual member of the system.
The center of mass is a useful reference point for calculations in mechanics that involve masses distributed in space, such as the linear and angular momentum of planetary bodies and rigid body dynamics. In orbital mechanics, the equations of motion of planets are formulated as point masses located at the centers of mass. The center of mass frame is an inertial frame in which the center of mass of a system is at rest with respect to the origin of the coordinate system.

A 18 g ball is swung at a 1m long string.It revolves every 1 s,what is the magnitude of swing's tension?
Answer:
The magnitude of swing's tension is 0.71 N.
Explanation:
Given;
mass of the ball, m = 18 g = 0.018 kg
angular speed of the ball, ω = 1 rev/s
radius of the motion, r = 1 m
Angular speed in rad/s is calculated as follows;
[tex]\omega = \frac{2\pi \ rad}{rev} \times \frac{1 \ rev}{s} \\\\\omega = 2 \pi \ rad/s[/tex]
Linear speed of the ball, v;
v = ωr
v = 2π x 1
v = 2π m/s
The magnitude of swing's tension is calculated as the centripetal force keeping the ball in circular motion.
[tex]F_c =T = \frac{mv^2}{r} \\\\T= \frac{0.018 \ \times (2\pi )^2}{1} \\\\T = 0.71 \ N[/tex]
Therefore, the magnitude of swing's tension is 0.71 N.
Why do you think lightning is so dangerous if it strikes a person?
Do you remember the old fashioned flashlights, before there were LEDs ?
They had two or three heavy batteries in the tube, and one little tiny glass light bulb in the middle of the little headlight in the front. When the batteries were fresh, that little light bulb gave out a nice bright beam of light, and drew about 0.7 Amperes from the batteries. That's the number I want you to remember for a couple of minutes: Flashlight bulb, 0.7 Amperes.
-- The wiring (nerves) that operate your heart can go haywire, and your heart can stop or go crazy, if 0.015 Amp of current or more happens to pass close by it.
-- The muscles in your arms or legs, or your diaphragm that makes you breathe, can lock up so that you can't control them, if 0.1 Amp of current or more happens to pass by them. If that current is 0.5 Amp or more and passes close to a muscle, the muscle can lock up so violently that it breaks the arm- or leg-bone that it's attached to.
Lightning is electric current flowing between a cloud and the ground. If anything is in the path it wants, it just flows right on through.
Lightning may flow in either direction ... up to the cloud or down to the ground. It really doesn't make any difference. The effects are the same, on anything it decides to flow through.
The current in a typical, average lightning bolt is 30,000 Amperes. A lot of them are bigger.
Current flowing through anything causes heat to be generated.
The more current = the more heat.
-- Lightning flowing through the wall of a house generates enough heat inside the wall to make the wall explode.
-- Lightning flowing through the juice inside a tree generates enough heat to boil the tree juice, and explode the tree.
-- Lightning flowing through the air heats a skinny tube of air so hot and so fast that the air explodes. That makes a strong sound wave in the air, that can be heard from miles away. It's called "thunder".

A day-care center has a merry-go-round that consists of a uniform 240-kg circular wooden platform 4.00m in diameter. Four children run alongside the merry-go-round and push tangentially along the platform’s circumference until, starting from rest, the merry-go-round is spinning at a rate of 2.14 rev/minute. During the spin-up:
a) If each child exerts a sustained force of 26N, how far does each child run?
b) What is the angular acceleration of the merry-go-round?
SHOW ALL WORK AND STEPS PLEASE.
Answer:
a) The distance each child ran is approximately 0.232 m
b) The angular acceleration is 0.21[tex]\overline 6[/tex] rad/s²
Explanation:
The given parameters of the merry-go-round are;
The mass of the merry-go-round, m = 240-kg
The diameter of the merry-go-round, d = 4.00 m
The number of children pushing tangentially on the merry-go round = Four children
The spinning rate of the merry-go-round, n = 2.14 rev/minute
a) Given that the force exerted by each child = 26 N, we have;
The total force applied by the four children, F = 26 N × 4 = 104 N
The tangential acceleration, [tex]a_t[/tex] = F/m = 104 N/240-kg = 0.4[tex]\overline 3[/tex] m/s²
The angular acceleration, α = [tex]a_t[/tex]/r
Where, the radius of the merry-go-round, r = d/2
∴ r = 4.00 m/2 = 2.00 m
α = 0.4[tex]\overline 3[/tex] m/s²/(2.00 m) = 0.21[tex]\overline 6[/tex] rad/s²
We have;
ω² = ω₀² + 2·α·Δθ
The merry-go-round starts from rest, therefore; ω₀ = 0 rad/s
ω² = 2·α·Δθ
Δθ = ω²/(2·α)
n = 2.14 rev/minute
∴ ω = 2·π×2.14/60 rad/s ≈ 0.22410 rad/s
∴ Δθ = (0.22410 rad/s)²/(2 × 0.21[tex]\overline 6[/tex] rad/s²) ≈ 0.11589 rad
Therefore, the angle each child ran, θ = 0.11589 rad
The distance each child ran = r·θ
∴ The distance each child ran = 2.00 m × 0.11589 rad ≈ 0.232 m
b) From part 'a' above, the tangential acceleration, [tex]a_t[/tex] = 0.4[tex]\overline 3[/tex] m/s²
Angular acceleration, α = [tex]a_t[/tex]/r
∴ α = 0.4[tex]\overline 3[/tex] m/s²/(2.00 m) = 0.21[tex]\overline 6[/tex] rad/s²
The angular acceleration = 0.21[tex]\overline 6[/tex] rad/s²

A block of mass m is placed against the inner wall of a hollow cylinder of radius R that rotates about a vertical axis with a constant angular velocity, ω, as shown above. In order for friction to prevent the mass from sliding down the wall, the coefficient of static friction, μ, between the mass and the wall must satisfy which of the following inequalities? (Ans: μ is greater than or equal to g/(w^2r)
Answer:
See explanation below
Explanation:
Recall that the force of static friction is the product of the coefficient of static friction between surface and object, times the force applied perpendicular to the surface.
In our case, that perpendicular force has magnitude equal to the centripetal acceleration times the mass m of the block. The centripetal acceleration is defined as the quotient between the square of the tangential velocity divided by the radius at which the rotating mass is located (in our case R).
In order to estimate the tangential velocity given the angular velocity ω, we simply multiply it by R:
[tex]v_t=\omega\,R[/tex]
and therefore the force acting on the surface of the cylinder is:
[tex]F=m\,*\,a_c=m\,*\,\frac{v_t^2}{R} =m\,*\, \frac{\omega^2\,R^2}{R} =m\,*\,\omega^2\,*R[/tex]
The force of friction between the block and the inner wall of the hollow cylinder will then be: [tex]f=\mu\, *\,m\,*\omega^2\,*\,R[/tex]
In order for this force of static friction to be able to prevent the mass to slide down due to gravity, we need that the friction force is at least equal to the gravitational force. That is:
[tex]f\geq F_g\\f\geq m\,*\,g\\\mu\,*\,m\,*\,\omega^2\,*\,R\geq m\,*\,g\\\mu\geq \frac{g}{\omega^2\,*\,R}[/tex]
The force of static friction to prevent the mass to slide down due to gravity, the friction force is must be equal or greater than to the gravitational force.
The force of static friction is the product of the coefficient of static friction between surface,and force applied perpendicular to the surface.
The tangential velocity,
[tex]\bold {V_t = \omega R}[/tex]
So, the force acting on the surface of the cylinder,
[tex]\bold {F= m\times a_c}\\\\\bold {F= m \times \dfrac {V_t^2 }{R}}\\\\\bold {F = m \times \dfrac {\omega ^2R2}{R}}}\\\\\bold {F = m \times \omega ^2 \times R}[/tex]
The force of friction between the block and the inner wall of the hollow cylinder,
[tex]\bold {F_f = \mu \times m \times \omega ^2 \times R}[/tex]
Therefore, the force of static friction to prevent the mass to slide down due to gravity, the friction force is must be equal or grater than to the gravitational force.
