Answer:

El coeficiente de fricción entre el bloque y el piso es 0,64.

Explanation:

Podemos hallar el coeficiente de fricción usando la definición de trabajo:

\( W = \Delta K = K_{f} - K_{i} = -K_{i} = -\frac{1}{2}m*v^{2} \)

En donde:

Kf es la energía cinética final =0

Ki es la energía cinética inicial

m: es la masa = 2 kg

v: es la velocidad = 5 m/s

Además el trabajo es el producto de la fuerza de rozamiento (Fr) por el desplazamiento (d), por lo que tenemos:

\( -Fr*d = -\frac{1}{2}m*v^{2} \)

\((\mu mg)d = \frac{1}{2}m*v^{2}\)

\( \mu = \frac{v^{2}}{2gd} = \frac{(5 m/s)^{2}}{2*9,81 m/s^{2}*2 m} = 0,64 \)

Por lo tanto, el coeficiente de fricción entre el bloque y el piso es 0,64.

Answer:

The resistance of the 60 Watt light bulb is 240 ohms.

Explanation:

To calculate the resistance of the light bulb, we can use Ohm's Law, which states that resistance (R) is equal to voltage (V) divided by current (I). In this case, we are given the voltage (V = 120 V) and the current (I = 500 mA = 0.5 A). However, we first need to convert the power (60 Watts) into current using the equation P = IV.

P = IV

60 W = (0.5 A) * V

Now, we can rearrange the equation to solve for voltage:

V = (60 W) / (0.5 A)

V = 120 V

Now, we have the voltage (V = 120 V) and the current (I = 0.5 A). We can substitute these values into Ohm's Law to calculate the resistance:

R = V / I

R = 120 V / 0.5 A

R = 240 Ω

Truths can be opinionated and can change at any time. A truth is the state of something from a person's point of view; essentially, it is their view of reality. Truths can vary from person to person, for example some may believe that there is a god, others may not, and others may think differently than that. To them, their truth is reality. Facts, however, are impartial. They have been proven and supported over time, and tend to be accurate for long periods of time. They are a far better option than truths for science.

Basically, in science, you shouldn't use truths because they are different from person to person while facts have been proven accurate.

An example of a contractile source of motion restriction is the contraction of muscles in the human body.

Muscles in the human body play a crucial role in generating movement and controlling motion. Through the process of contraction, muscles have the ability to restrict or limit motion at specific joints, acting as a contractile source of motion restriction.

When muscles contract, they exert a pulling force on the bones they are connected to, resulting in movement at the joints. This contraction is achieved through the interaction of actin and myosin filaments within the muscle fibers. When a signal from the nervous system triggers muscle activation, calcium ions are released, allowing the actin and myosin filaments to slide past each other. This sliding motion generates force, causing the muscle fibers to shorten and contract.

By selectively contracting specific muscles, it is possible to restrict or limit motion at certain joints. For example, when you contract your bicep muscle, it restricts the motion at the elbow joint, causing the arm to bend. Similarly, when you contract your quadriceps muscles, they restrict the motion at the knee joint, allowing you to extend or straighten your leg.

In summary, the contraction of muscles serves as a contractile source of motion restriction. Through their ability to generate force and control joint movement, muscles play a crucial role in enabling and regulating various motions in the human body.

Answer: Energy is released to the environment.

Explanation:

In conclusion, to find the wavelength of the laser, we measured the displacement of the mirror and calculated the fringe spacing. By multiplying the fringe spacing by 2, we determined the wavelength of the laser to be 0.0003164 mm (or 316.4 nm).

To find the wavelength (λ) of the laser, we can use the given information. When you shine the laser into the interferometer and move one of the mirrors, you observe 100.0 fringes passing the crosshairs of the telescope. By measuring the displacement of the mirror using the accurate micrometer (0.03164 millimeters), we can determine the wavelength of the laser.
Here's how we can calculate it:
1. Recall that the distance between two adjacent fringes is equal to half the wavelength of the laser. So, if we count 100 fringes passing the crosshairs, we've actually observed 200 fringe spacings.
2. Divide the displacement of the mirror (0.03164 mm) by the number of fringe spacings observed (200) to get the fringe spacing (δ).
  δ = 0.03164 mm / 200 = 0.0001582 mm
3. Finally, multiply the fringe spacing (δ) by 2 to get the wavelength of the laser (λ).
  λ = 2 * δ = 2 * 0.0001582 mm
To convert the wavelength from millimeters to meters, you can divide by 1000:
  λ = 2 * 0.0001582 mm / 1000 = 0.0003164 mm
Therefore, the wavelength of the laser is 0.0003164 mm (or 316.4 nm).
In conclusion, to find the wavelength of the laser, we measured the displacement of the mirror and calculated the fringe spacing. By multiplying the fringe spacing by 2, we determined the wavelength of the laser to be 0.0003164 mm (or 316.4 nm).

 volume of a sphere = 4/3 pi r^3

                                   = 4/3 pi * (1.5)^3 = 14.14 m^3   <===balloon volume

Now,   find the buoyant force on the container ALONE ....

             5.8 * 2.6 * 2.8  * 1027  = 43 364  kg   <=====  buoyant force

The speed at which the motor will run on no-load can be determined by using the concept of the motor's input and output power.
Given:
Full-load power (output power) = 7.5 kW
Full-load efficiency = 86% = 0.86
Total no-load input power = 600 W
First, we can calculate the full-load input power using the efficiency formula:
Full-load input power = Full-load power / Full-load efficiency
Full-load input power = 7.5 kW / 0.86 = 8.72 kW
Now, we can determine the ratio of the no-load input power to the full-load input power:
Power ratio = Total no-load input power / Full-load input power
Power ratio = 600 W / 8.72 kW = 0.0688
Since power is directly proportional to the speed of the motor, we ca
calculate the speed on no-load using the power ratio
No-load speed = Full-load speed * √(Power ratio)
No-load speed = 1,200 r/min * √(0.0688) ≈ 292.78 r/min
Therefore, the motor will run at approximately 292.78 r/min on no-load.
1.2.2 To reduce the speed to 1,000 r/min when giving full-load torque, we need to add a resistance in the armature circuit. The speed of the motor is inversely proportional to the armature circuit resistance.
Given:
Full-load speed = 1,200 r/min
Target speed = 1,000 r/min
Using the speed ratio formula:
Speed ratio = Full-load speed / Target speed
Speed ratio = 1,200 r/min / 1,000 r/min = 1.2
Since the speed is inversely proportional to the resistance, we can calculate the resistance ratio:
Resistance ratio = 1 / Speed ratio
Resistance ratio = 1 / 1.2 ≈ 0.833
Now, we can calculate the required resistance to be added in the armature circuit:
Required resistance = Armature circuit resistance * Resistance ratio
Required resistance = 0.3 ohm * 0.833 ≈ 0.25 ohm
Therefore, a resistance of approximately 0.25 ohm needs to be added in the armature circuit to reduce the speed to 1,000 r/min when giving full-load torque, assuming the flux is proportional to the field current.

Explanation:

In the given question, in order for the student to lift the boxes onto the tuck with less amount of force, he applies the principle of Mechanical Advantage

The mechanical advantage is given by the measure by which a force is amplified through the use of a tool

Given that the work done = The force × The distance, we have

F₁ × d₁ = F₂ × d₂, which gives;

d₁/d₂ = F₂/F₁

Where;

F₁ = The input force

F₂ = The output force

The seasons in Wellington are:

A season is a division of the year that is based on variations in weather, ecology, and the number of daylight hours in a particular place. Seasons on Earth are caused by the axial parallelism of Earth's tilted orbit around the Sun.

Seasons have a huge impact on vegetation and plant development. Winter weather is often chilly, with little sunshine and restricted plant development. Plants grow, tree leaves unfold, and flowers bloom in the spring. Summer is the hottest season with the greatest daylight, therefore plants grow fast.

Winter in Wellington is very brief and mild, with only a few frosty days. Wellington's temperature seldom rises over 25°C (77°F) or falls below 6°C (43°F).

An unopened bag of chips expanding as one drives up a mountain is a good example of how volume increases when pressure decreases.

When driving up a mountain, the atmospheric pressure decreases due to the decrease in air density at higher altitudes. As the external pressure decreases, the air inside the bag of chips exerts a higher pressure relative to the lower external pressure.

This pressure difference causes the bag to expand, increasing its volume. Therefore, the volume increases when the pressure decreases in this scenario.

Explanation:

Colloid osmotic pressure is the oncotic pressure which is opposite to the hydrostatic blood pressure.

Oncotic pressure is the colloid osmotic-pressure. It is a form of osmotic pressure which is induced by the proteins, notably the albumin protein, in a blood vessel's plasma which causes a pull on the fluid back into the capillaries in the body. Participating colloids displace the water molecules, thus creating a relative water molecule deficit with the water molecules moving back into the circulatory system in the body within the lower venous pressure end of capillaries.

Colloid osmotic-pressure has the opposing effect of both the hydrostatic blood pressure pushing water molecules and the small molecules which are out of the blood into interstitial spaces within the arterial end of the capillaries and interstitial colloidal osmotic pressure. These interacting factors can determine the partition balancing of extracellular water between the blood plasma and outside the blood stream.
