Para hacerlo a m/s un método muy práctico es sólo dividir entre 3.6, por cuestiones de conversiones, lo puedes comprobar.

212 km/hr /3.6 = 58 m/s

Comprobación :

V= d / t

V= 212 m / 18000 seg <---- nota que aquí los segundos son de las 3.1hrs  

V= 58 m/seg

Answer:

The statements are not given, so I will answer in a general way.

We know that when one object is moving with a velocity V, and it wants to come to stop, it needs to accelerate in the opposite direction to the initial velocity (Or decelerate).

As larger this acceleration is, the faster the object will come to a full stop.

Now we have a car (with a mass m) and a truck (with a mass M) are moving with a velocity V.

We can assume that the mass of the truck is larger than the mass of the car, then:

M > m.

Now also remember Newton's second law:

F = m*a

Force equals mass times acceleration.

And we know that both vehicles stop with the same stopping force.

Then the acceleration (deceleration actually) that experiences the car is:

a = F/m

While the acceleration that experiences the truck is:

a' = F/M

Because M is larger than m, we will have:

a' < a

Then the deceleration of the truck is smaller than the one of the car, which means that the car will come to a full stop faster than the truck (or the truck needs more time to stop)

Interview refers to an official face-to-face meeting of monarchs or other important figures.

Answer:

Facts and theories are two different things. In the scientific method, there is a clear distinction between facts, which can be observed and/or measured, and theories, which are scientists' explanations and interpretations of the facts.

Explanation:

Answer:

Facts can be proven with studies and evidence, and theories are assumptions made by people that have not been proven.

Explanation:

The combined kinetic energy of the cyclist and cycle is 6120 J.

It takes 34 seconds for the kinetic energy of the cyclist and cycle to increase by 6120 J at a rate of 180 J/s.

(i) The kinetic energy of an object is given by the formula:

KE = 1/2 * m * v^2

where KE is the kinetic energy, m is the mass of the object, and v is its velocity.

For the cyclist and her cycle traveling at a speed of 12 m/s, the kinetic energy is:

KE = 1/2 * (85 kg) * (12 m/s)^2 = 6120 J

Therefore, the combined kinetic energy of the cyclist and cycle is 6120 J.

(ii) The rate of change of kinetic energy is given by the formula:

P = dKE/dt

where P is the power, KE is the kinetic energy, and t is time.

We are given that the kinetic energy increases at a rate of 180 J/s. Therefore, the power is:

P = 180 J/s

We can rearrange the formula for power to solve for time:

t = dKE/P

Substituting the values, we get:

t = dKE/P = 6120 J / 180 J/s = 34 s

Therefore, it takes 34 seconds for the kinetic energy of the cyclist and cycle to increase by 6120 J at a rate of 180 J/s.

Explanation:

F = ma, therefore F = 0.25 kg * 32m/s^2.

Answer:

Explanation: Thermal energy is transferred through water by conduction, convection, and radiation. Conduction occurs when heat is transferred through direct contact between water molecules with different thermal energy. Convection occurs when warmer water rises to the top and cooler water sinks to the bottom, creating a circular motion that distributes heat. Radiation is the transfer of energy through electromagnetic waves, but it is not significant in water due to poor conduction. The specific mechanism that dominates heat transfer depends on various factors such as temperature gradient, depth, and presence of other materials.

Answer:

The correct option is  B

Explanation:

From the question we are told that

  The terminal  velocity of both balls is  \(v_t  =  32 \ m/s\)

   The speed with which ball A is thrown up at t =0 s is  \(v__A}}  =  16\sqrt{2}\)

   The speed with which ball B is thrown 30° below the horizontal  at t =0 s is  

\(v__{B}} =  32\sqrt{2}\)

Generally the acceleration of ball A is (g i.e acceleration due gravity)given that it is thrown straight up  

Generally the vertical  acceleration of ball B is mathematically represented as

    \(a  = gcos (90 - 30)\)

      \(a  = gcos (60)\)

Generally the ratio of both acceleration is  

     \(\frac{a__{{A}}}{a__{{B}}}} =\frac{g}{gsin(60)}\)

=> \(\frac{a__{{A}}}{a__{{B}}}} = \frac{1}{sin (60)}\)

=>  \(\frac{a__{{A}}}{a__{{B}}}} = \frac{1}{\frac{\sqrt{3} }{2} }\)

=>\(\frac{a__{{A}}}{a__{{B}}}} = \frac{2}{\sqrt{3} }\)

Rationalizing

=> \(\frac{a__{{A}}}{a__{{B}}}} = \frac{2}{\sqrt{3} } *\frac{\sqrt{3} }{\sqrt{3} }\)

=> \(\frac{a__{{A}}}{a__{{B}}}} = \frac{2 \sqrt{3} }{3}\)

=>\(a__{B}} = \frac{2\sqrt{3} }{3} * a__{A}}\)

Angular velocity is the rate at which an object moves around an axis of rotation. The closer an object is to the axis of rotation, the smaller its radius and the slower its angular velocity. This means that the girl, who is closer to the axis of rotation, will have a slower angular velocity compared to the boy, who is at the outer edge of the merry-go-round.

This can be explained using the formula for angular velocity: ω = v/r, where ω is the angular velocity, v is the linear velocity, and r is the radius. Since the merry-go-round is turning at a constant speed, the linear velocity of both the boy and the girl is the same. However, the radius of the boy is larger than the radius of the girl. Therefore, the boy's angular velocity is greater than the girl's angular velocity.

In summary, the boy's angular velocity is greater than the girl's because he is farther away from the axis of rotation and has a larger radius. The girl, who is closer to the axis of rotation, has a smaller radius and a slower angular velocity.

Answer:

\(v = u + gt \\ v = (0) + 9.8(4) \\ v = 39.2 \: m. {s}^{ - 1} \)

Answer:

Distance, S = 13m

Explanation:

Given the following data;

Initial velocity, u = 4m/s

Final velocity, v = 9m/s

Time, t = 2 seconds

To find the distance, S;

First of all, we would determine the acceleration of the shark.

Acceleration = (v - u)/t

Acceleration = (9 - 4)/2

Acceleration = 5/2

Acceleration = 2.5m/s²

Now, to find the distance we would use the second equation of motion

S = ut + ½at²

Substituting into the equation, we have

S = 4(2) + ½*2.5*2²

S = 8 + 1.25*4

S = 8 + 5

Distance, S = 13m

(3) Knowing an object’s position requires which of the following displacement ( option C).

(4) Two people are pulling on a chain in opposite directions with forces of 500 N and 600 N. The forces would best be described as unbalanced forces ( option B).

(5) The reference point can change when describing motion. It is just the chosen starting point (option C ).

(6) Which of the following is NOT true of gravitational force, depends on speed ( option C ).

The displacement of an object is the change in the position of the object, obtained from the difference between the object's final position and initial position.

When two people pulling on a chain in opposite directions with forces of 500 N and 600 N, the forces would best be described as unbalanced forces because 600 N is greater than 500 N.

A reference point is a place or object used for comparison to determine if something is in motion. When describing motion, the reference point can change to show  the motion of the object.

When a light wave travels from air into glass, the correct answer is:

B) Its speed decreases.

When light passes from one medium to another, such as from air to glass, it encounters a change in the refractive index of the material. The refractive index is a property of a medium that describes how much the speed of light changes when passing through that medium.

In general, the speed of light is slower in a denser medium like glass compared to air. As the light wave enters the glass, it slows down due to interactions with the atoms or molecules in the material. This change in speed is accompanied by a change in direction, which is known as refraction.

However, the wavelength of the light wave does not change significantly when it travels from air into glass, so option C is not correct. Similarly, the frequency of the light wave remains the same, as it is a property of the light wave itself and is not affected by the medium it travels through, making option E also incorrect.

The transformer operates based on the principle of electromagnetic induction this equation shows that the primary coil has twenty-two times as many turns as the secondary coil.

Let's denote the number of turns in the primary coil as Np and the number of turns in the secondary coil as Ns.

The transformer operates based on the principle of electromagnetic induction, which states that the ratio of the number of turns in the primary coil to the number of turns in the secondary coil is equal to the ratio of the input voltage to the output voltage. Mathematically, this can be expressed as:

Np / Ns = Vin / Vout

In this case, the input voltage (Vin) is 220 V and the output voltage (Vout) is 10 V. Substituting these values into the equation, we get:

Np / Ns = 220 / 10

Simplifying further:

Np / Ns = 22

Answer:

We conclude that if a flat piece of paper or blowing ball is dropped from the same height, They would hit the ground at the same time.

Thus,

option a) is correct.

Explanation:

When there is no air in the space, it is basically a vacuum.

So, when there is no air in space, it means there is no force that can act on the body.

As there is no force that can act on an object in the vacuum, it means every object in the vacuum seems to stand still while falling.

Therefore, we conclude that if a flat piece of paper or blowing ball is dropped from the same height, They would hit the ground at the same time.

Thus,

option a) is correct.

Using the concepts of motion, we got that 0.816m is the maximum vertical height the box will reach if its initial velocity at the bottom of the ramp is 4.0 m/s.

We use Newton`s third equation of motion,

v² -u²=2aS---------(eq1)

where

v is the final velocity, and u is the initial velocity and a is the acceleration of the object and S is the displacement of the object.

We know, that at the maximum height, final velocity will be =0

Acceleration will be acceleration due to gravity(g)=9.8m/sec² .

Putting the values in (eq1)

=>0-(4)² = 2×(-9.8)×S

=>2×9.8×S = 16

=>S = [(16)/(2×9.8)]

=>S = 8/9.8

=>S =0.816m

Hence, the the maximum vertical height the box will reach if its initial velocity at the bottom of the ramp is 4.0 m/s is 0.816m

The sound will be a more tolerable 80 dB at a distance of approximately 39.7 m from the source.

The sound intensity level of a large power saw decreases as the distance from the source increases. This decrease follows an inverse square law, meaning that the sound intensity decreases by a factor of 4 for every doubling of the distance from the source. This means that to decrease the sound intensity level from 100 dB to 80 dB, the distance from the source must be increased by a factor of 10^(100-80)/10, which is approximately 7.94 times. So, if the sound intensity level is 100 dB at a distance of 5 m from the source, the sound will be a more tolerable 80 dB at a distance of approximately 39.7 m from the source. However, it's important to note that this is just an estimate and the actual sound level will depend on the specific conditions of the environment, including the presence of any obstacles that can affect the sound wave propagation.
