Answer:

Its A

Explanation:

Because the pressure exerted by the gas in the tank would increase.

The statement that predicts what would happen if the scuba tank were to increase in temperature is that pressure exerted by the gas in the tank would increase.

The pressure and temperature of a gas in a container is connected by the pressure law equation, which states as follows:

P1/T1 = P2/T2

This equation depicts that an increase in the pressure of a gas also increases the temperature.

Therefore, the statement that predicts what would happen if the scuba tank were to increase in temperature is that pressure exerted by the gas in the tank would increase.

Explanation: The answer is Cork because:

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

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 person is made of lots of nice soft, moist, mushy stuff, water, juices, and air.  A thousand Amperes flowing through it all can do a fast, efficient, complete job of heating it, boiling it, cooking it, exploding it, and tearing it to pieces.  

Sounds dangerous to me.

Explanation:

If the roller coaster car in the above problem were moving at twice the speed, then 16000 Joules is the new kinetic energy.

Kinetic energy is a type of power that a moving object or particle possesses. An item accumulates kinetic energy when work, which involves the transfer of energy, being done on it by exerting a net force.

A object in motion or particle has kinetic energy, which relies on both its mass and its rate of motion. Any combination of movements, including translation, rotation along an axis, and vibration, may constitute the kind of motion.

kinetic energy= ½mv²

v =4m/s

m= 2000kg

KE = ½ (2000) (4)²

    =16000 Joules

Therefore, If the roller coaster car in the above problem were moving at twice the speed, then 16000 Joules is the new kinetic energy.

B. Mass

Explanation:

mass Includes newton which is a measure of force

weight is a measure of force. hence option D is correct.

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.

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.

Answer:

The final velocity of your motion is 19.5 m/s.

Explanation:

Given;

initial velocity of your motion, u = -3.0 m/s

acceleration of your motion, a = 2.5 m/s²

time of your motion, t = 9.0 s

The final velocity of your motion is calculated as follows;

v = u + at

where;

v is the final velocity

substitute the given values and solve for v

v = -3.0 + (2.5 x 9)

v = -3.0 + 22.5

v = 19.5 m/s

Therefore, the final velocity of your motion is 19.5 m/s.

Answer:

65m

Explanation:

Twelve waves pass a dock in 3.60 If the waves are traveling at 19.5 m/s , what is the wavelength of the waves?

Velocity of a wave is expressed as;

V = frequency × wavelength

Given

Velocity = 19.5m/s

Frequency is the number of oscillations completed in 1sec, hence

Frequency= 3.6/12

Frequency = 0.3

Wavelength = vel/freq

Wavelength = 19.5/0.3

Wavelength = 65m

The farther you live from an ocean, the more likely you will have a continental climate where there are extreme temperature differences in summer and winter

Inland regions have continental climates. To feel the impacts of ocean water, they are too distant from oceans. Between 40 and 70 degrees north latitude, continental climates are typical.

Northern Ukraine, eastern Belarus, Russia, the majority of Finland, and northern Sweden all have climates that are classified as continental. The northeast has the coldest winters and warmest summers, with winters being significantly colder, longer, and covered in more snow than in western Europe.

Given data ,

Let the land be situated at a place where it is farther away from the ocean

Now , there will be extreme temperature differences during the summer and the winter time

And , winters may be quite cold and summers can be very hot in continental climes. As there is less water in the continental environment than there is in marine climates, the temperatures are not as warm.

Hence , the continental climate takes place the farther you live from an ocean

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.
