What is Bernoulli's principle?

It gives the relationship between pressure, kinetic energy, and gravitational potential energy of a fluid in a container .

P₁ + 1/2ρv₁² + ρgh₁ = P₂ + 1/2ρv₂² + ρgh₂

Since it is a open tank,

P₁ = P₂ = P₀ , atmoshperic pressure

h₁ = 50m

h₂ = 5m

v₁ = 0

Applying Bernoulli's principle

P₁ + 1/2ρv₁² + ρgh₁ = P₂ + 1/2ρv₂² + ρgh₂

P₀ + 0 + ρgh₁ = P₀ + 1/2ρv₂² + ρgh₂

ρgh₁ = 1/2ρv₂² + ρgh₂

v₂ = √(2g(h₁-h₂))

  =  √(2×9.8(50-5))

 =  29.698 m/s

Therefore the velocity which the water flow out of the tank  is  29.698 m/s

Explanation:

The density of the tennis ball = 0.38 g/cm³

The density of the golf ball = 1.13 g/cm³

The mass of the tennis ball = 56 g

The volume of the tennis ball = 149 cm³

The density of the tennis ball can be found using the formula,

            d = m/v

where d is the density

          m is the mass

          v is the volume

Let us substitute the known values in the above equation, we get

           d = 56 / 149

              = 0.38 g/cm³

The mass of the golf ball = 45.9 g

The volume of the golf ball = 40.68 cm³

The density of the golf ball is

Precursors are the building blocks or the starting materials that the body uses to synthesize neurotransmitters. The correct answer is 5. precursor.

Neurotransmitters are chemical messengers that transmit signals between nerve cells in the brain and the rest of the body.

Here,
Precursors are the building blocks or the starting materials that the body uses to synthesize neurotransmitters. The process of neurotransmitter synthesis involves a series of enzymatic reactions, where precursors are transformed into neurotransmitters and stored in synaptic vesicles.

When a nerve impulse reaches the end of a neuron, the synaptic vesicles release the neurotransmitters into the synaptic cleft, where they bind to receptors on the postsynaptic neuron and transmit the signal. The neurotransmitter molecules are then either reabsorbed by the presynaptic neuron or broken down by enzymes, such as those involved in neurotransmitter degradation.

The temperature of the upper disk T1​;

Let's now think about the net rate of radiation from the upper disk. If we take a look at the given figure we will notice that the heat is transferred by radiation from surface A1​ to both lower disk of surface A2and the surroundings. So, we will write the net rate of heat transfer from A1as:

Q˙​1​​=Q˙​12​+Q˙​1,surr​

where: σ=5.67⋅10−8 W m2K2σ=5.67⋅10−8 m2K2 W​.

According to eq. (2), the unknown values that have to be determined in order to calculate T2 are:

 Surface area A1A1​;

 The view factors F12F12​ and F1,surrF1,surr​.

The surface area A1A1​ is the surface of the disk, calculated using the well-known equation:

A1=D12π4=0.22π4=0.0314 m2

This was easy. Let's move on to a little bit more difficult part, which is determining the view factors.

We will now calculate the view factor F12F12​. Since surfaces A1A1​ and A2A2​ are coaxial parallel disks, the view factor will be determined using the following expression:

Remember that distance between the disks is given to be:

L=0.2 m

L=0.2 m

Therefore, we will calculate SS as:

S=1+1+(0.20.2)2(0.10.2)2=1+1+0.520.52=9

Now, let's substitute values to eq. (3) and determine the view factor from the upper to the lower disk:

F12​​=21​⎝

⎛​9−[92−4(0.10.2​)2]1/2⎠

⎞​=0.47​

Next, by applying the summation rule for surfaceA1A1​, F1, surrF1, surr​ will be determined:

F11+F12+F1, surr=1F1, surr=1−F11−F12=1−0−0.47=0.53

Note: The disk is a plate surface that can not see itself. Therefore, the view factor from the plate surface to itself is equal to zero: F11=0F11​=0.

Now, that we have all the values we need, by substituting them into eq. (2), it follows:

17.5=1⋅5.67⋅10−8⋅0.0314⋅[0.47⋅(T14−5004)+0.53⋅(T14−3004)]17.5=0.178⋅10−8⋅[0.47⋅(T14−5004)+0.53⋅(T14−3004)]

17.517.5​=1⋅5.67⋅10−8⋅0.0314⋅[0.47⋅(T14​−5004)+0.53⋅(T14​−3004)]=0.178⋅10−8⋅[0.47⋅(T14​−5004)+0.53⋅(T14​−3004)]​

Finally, if we rearrange the previous equation, we will calculate the temperature of the upper disk:

0.08366⋅10−8⋅T14+0.09434⋅10−8⋅T14=17.5+49.94+7.640.178⋅10−8⋅T14=75.08T14=75.080.178⋅10−8T1=421.8⋅1084=453.2 K

0.08366⋅10−8⋅T14​+0.09434⋅10−8⋅T14​0.178⋅10−8⋅T14​T14​T1​​=17.5+49.94+7.64=75.08=0.178⋅10−875.08​=4421.8⋅108

The recessional velocity of the galaxy is 2.70×10⁻³km/s

Simply put, recessional velocity is the speed at which an item is moving away from the observer. The Doppler Effect and redshift both depend heavily on this idea. The recessional velocity in the Doppler Effect can be determined by extrapolating the wavelength of the waves from their rest wavelength.

We are given that,

Velocity = v = 25000 km/s

Distance = d = 108 light years

Hubble's law states: If the galaxy's moving velocity is given by v, and its distance from Earth is given by d, and H is the Hubble constant, we can write as,

v = H×d

v = (25 km/s per million light years)×108 light years

v = (2.5×10⁻⁵ km/s per light years)×108 light years
