What is the trademark of the Harlem Globetrotters?

Answer:

In reality, the filament gets so hot it in a real sense bubbles off molecules and electrons. Now and again this material gathers as a dull spot at the highest point of the bulb. Eventually, the filament falls apart, gets frail, and breaks, subsequently finishing the life of the light. Lights radiate light by siphoning an electric flow through a dainty tungsten fiber. The filament warms and emits light. Over the long haul, the filament oxidizes and turns out to be increasingly fragile, until it splits up and the bulb goes out. ... Tungsten picks up obstruction as it warms.

Explanation:

A car started from rest and accelerated at 9.54 m/s^2 for 6.5 seconds. How much distance was covered by the car?

Use the formula  d = \(\frac{at^{2} }{2} ,\)

where d is the distance, t is the time and "a" is the acceleration.
\(d=\frac{9*54*6*5^{2} }{2} = 201.53 m\)

If you look at courage and if you look at the brain, there is one particular brain structure that plays a very important role when it comes to courage and your own performance. This part of the brain is called the amygdala. The amygdala is a brain structure that is very small, and we have two of them, one of the left side of the brain, one on the right side of the brain. They’re very small and look like an almond. Amygdala is also the Latin word for almond. Even though they are small, they amygdala is also extremely powerful. It plays a very important role in our survival. Whenever there is a real danger outside, it will trigger a fight, flight or freeze response, so you will fight danger, run away, or just be blocked in your own emotions, you will freeze, perhaps you will hide. The amygdala is very important for our survival and for many emotions in general, but in many situations, the amygdala will also become active when there is no real danger, for example, standing on stage and holding a presentation, leading a difficult conversation. These are two examples where there’s no real danger, but nevertheless, the amygdala can be triggered and cause this feeling of nervousness and anxiety. It’s these feelings of nervousness, anxiety or insecurity that will also block us in our potential to hold a presentation or to lead a good conversation.

Explanation:

Light gets reflected by a medium of higher  refractive index and then from a medium of lower refractive index a second time  so there will  be an additional phase difference of 180⁰.

For constructive interference in thin films  the condition is as follows .

2μd = (2n+1) λ/2

where μ is 1.56 , d is 80 nm λ is wave length of ligh and n is an integer .

For longest wavelength , n = 0

λ = 4μd

= 4 x 1.56 x 80 nm

= 499.2  nm .

The spring constant for a spring is stretched 0.15 m and the force was 1500 N is 10000.

The spring constant, k, is a measure of the spring's stiffness. It varies depending on the spring and material. The greater the spring constant, the stiffer the spring and more difficult to stretch.

The letter k symbolizes the "spring constant," which is a number that tells us how "stiff" a spring is.

If k is large, it means that more force is required to stretch it a certain length than would be required to stretch a less stiff spring the same length.

We know that,

F = k(x)

Where k is the spring constant.

Here, it is given that:

F = 1500N

x = 0.15m

So,

1500 = k (0.15)

k (0.15) = 1500

k = 1500/0.15

k = 150000/15

k = 10000

Thus, the value of spring constant is 10000.

RS is a composition of rotation and reflection in the Euclidean plane E². The precise description of RS depends on the specific properties of the rotation R and reflection S.

In general, if R and S have the same axis or line of symmetry, the composition RS results in a translation. If R and S have intersecting lines of symmetry, RS yields a glide reflection. If R and S have perpendicular lines of symmetry, RS produces a rotation.

It is important to consider special cases, such as parallel lines of symmetry, coinciding axes, or perpendicular lines of reflection, as they may lead to different outcomes.

Answer:The principle that states that a change in pressure at any point in a fluid in a closed container is transmitted equally and unchanged in all directions throughout the fluid is known as Pascal's principle.

Explanation:.

In order to determine whether the current source is a good design for the chosen frequency range when the capacitor of fig. 15.2 is decreased to 0.01 uf, we need to consider the effect of the capacitor on the circuit's impedance. Capacitors have a capacitive reactance (Xc) that varies inversely with frequency, given by the equation Xc = 1/(2πfC), where f is the frequency and C is the capacitance.

When the capacitance is decreased to 0.01 uf, the capacitive reactance increases, meaning that the circuit's impedance increases at higher frequencies. This can have the effect of attenuating higher frequency signals and reducing the overall performance of the current source.

Therefore, if the chosen frequency range is above the cutoff frequency determined by the decreased capacitance, then the current source may not be a good design. However, if the chosen frequency range is well below the cutoff frequency, then the current source may still be a good design. It ultimately depends on the specific application and frequency requirements.

The work done by the gas for question A will be 4.2 * 10^5 J.

The change in internal energy of the gas for question B is 6.43 * 10^5 J.

For a gas, it is the product of the pressure P and the volume V during a change of volume. The formula for work done in gas is W (work) = P (pressure) * V (volume)

Now, let's calculate the work done by gas to answer question A.

Work = Pressure * (Volume 2 - Volume 1)

= 1 atm * (16.2 - 12)

= 10^5 Pa * 4.2

= 4.2 * 10^5 J

So the work done by the gas is 4.2 * 10^5 J.

Now, let's find the change in internal energy of the gas.

The heat energy added to the system is

Q = 254kcal

= 254kcal * (4184J / 1 kcal)

= 1.063 * 10^6 J

The change in internal energy of gas is

ΔU = Q (the heat energy added) - W (work done by gas)

= 1.063 * 10^6 J - 4.2*10^5 J

= 6.43 * 10^5 J

Therefore, the change in internal energy of the gas is 6.43 * 10^5 J

The most important factor in determining if an area will be subject to mass movement is gravity. However, other factors such as relief, weather, and water content can also play a role in increasing the likelihood of mass movement occurring.

A crucial aspect of activities involving mass movement is gravity. Materials move because of the pulling power of gravity, which drags them downslope. It affects slope stability and controls whether or not there will be mass movement.

Additional elements like relief (a), which describes topographic variance or landscape steepness, and water content (d) can affect slope stability and influence mass movement. These things are important, but not as important as gravity itself.

Slope steepness is influenced by relief, and steeper slopes are typically more prone to mass movement. However, the force that causes the materials to slide or collapse is gravity.

In conclusion, while relief, water content, and weather conditions can all affect how much mass moves, gravity is by far the most crucial element since it acts as the motor that starts and regulates the movement of materials downslope. Therefore, b) gravity is the right response.

What is nucleus ?

Neutrons and protons, which have opposite electric charges, make up atomic nuclei. The strongest basic force now understood, known as the strong force, is what holds these things together. A normal atom's nucleus generally holds more than 99.9% of the atom's mass yet takes up considerably less than.01 percent of its volume.

What is fission ?

When a neutron collides with a bigger atom, it excites it and causes it to split into two smaller atoms, which are known as fission products. This process is known as fission. A chain reaction might start as a result of additional neutrons that are also emitted. Huge amounts of energy are produced during the splitting of each atom.

Answer:

The energy that can be stored in the capacitor is 239 nJ

Explanation:

We first calculate the capacitance of each material. Let C₁ be the capacitance of pyrex glass and C₂ be the capacitance of polystyrene.

C₁ = κ₁ε₀A/d where κ₁ = dielectric constant of pyrex glass = 5, A = area of plates = L² where L = length of square plate = 7.40 cm = 7.40 × 10⁻² m and d = thickness of pyrex slab = 1.60 mm = 1.60 × 10⁻³ m and ε₀ = permittivity of free space = 8.854 × 10⁻¹² F/m

C₁ = κ₁ε₀A/d = κ₁ε₀L²/d = 5 × 8.854 × 10⁻¹² F/m × (7.40 × 10⁻² m)²/1.60 × 10⁻³ m = 2424.2252/1.60 × 10⁻¹¹ F = 1515.14 × 10⁻¹¹ F = 15.2 × 10⁻⁹ F = 15.2 nF

C₂ = κ₂ε₀A/d where κ₂ = dielectric constant of polystyrene = 3, A = area of plates = L² where L = length of square plate = 7.40 cm = 7.40 × 10⁻² m and d = thickness of polystyrene slab = 1.60 mm = 1.60 × 10⁻³ m and ε₀ = permittivity of free space = 8.854 × 10⁻¹² F/m

C₁ = κ₁ε₀A/d = κ₁ε₀L²/d = 3 × 8.854 × 10⁻¹² F/m × (7.40 × 10⁻² m)²/1.60 × 10⁻³ m = 1454.5351/1.60 × 10⁻¹¹ F = 909.08 × 10⁻¹¹ F = 9.09 × 10⁻⁹ F = 9.09 nF

Since the capacitors are in series, we find their effective capacitance C from

1/C = 1/C₁ + 1/C₂

C = C₁C₂/(C₁ + C₂)

= 15.2 × 10⁻⁹ F × 9.09 × 10⁻⁹ F/(15.2 × 10⁻⁹ F + 9.09 × 10⁻⁹ F)

= 138.168 × 10⁻¹⁸/24.29 × 10⁻⁹ F

= 5.69 × 10⁻⁹ F

The amount of electrical energy stored in a capacitor is given by W = 1/2CV² where C = capacitance and v = voltage applied. Now C = 5.69 × 10⁻⁹ F and V = 84.0 V for this capacitor

So W = 1/2 × 5.69 × 10⁻⁹ F × 84.0 V

= 238.98 × 10⁻⁹ J

≅ 239 × 10⁻⁹ J

= 239 nJ

So the energy that can be stored in the capacitor is 239 nJ

A medium is able to transport a wave from one location to another because the particles of the medium are (c)able to interact.

When a wave travels through a medium, it causes the particles in the medium to vibrate, and these vibrations are then passed on to neighboring particles, thus allowing the wave to propagate. In a solid, the particles are tightly packed and can interact strongly, allowing waves to travel quickly.

In liquids and gases, the particles are more spread out, and interactions between them are weaker, so waves travel more slowly.
