The mass of the water is 65.5 kg. The weight of the water is 641.9 kgm/s²

The mass of a spherical tank is the space contained in the tank. The mass of the spherical tank can be determined by first finding the volume of the tank, then using the relation of density, mass, and volume to find the mass.

From the given parameter:

The volume of the tank can be determined by using the formula:

\(\mathbf{V = \dfrac{4}{3}\pi r^3}\)

\(\mathbf{V = \dfrac{4}{3}\pi (0.25)^3}\)

V = 0.0655 m³

Using the relation that:

\(\mathbf{Density = \dfrac{mass}{volume}}\)

\(\mathbf{1000 \ kg/m^3= \dfrac{mass}{0.0655 \ m^3}}\)

mass = 1000 kg/m³ × 0.0655 m³

mass = 65.5 kg

The weight of the water can be determined by using the formula:

Weight = mass × gravity (i.e. acceleration due to gravity)

Weight = 65.5 kg × 9.8 m/s²

Weight = 641.9 kgm/s²

https://brainly.com/question/5493941

The mass of the water in spherical tank is 65.4kg.

The weight of the water in spherical tank is 640.8 Newtons.

Given the data in the question:

Mass of water; \(m_w = \ ?\)

Weight of water; \(Ww = \ ?\)

Density \(p\) is simply the measure of the compactness of the mass of a substance. It is expressed as;

\(Density = \frac{Mass}{Volume}\)

To determine the mass and weight of the water in spherical tank,

we calculate the Volume of the spherical tank.

\(V = \frac{4}{3}\pi r^3\)

We substitute in our given values

\(V = \frac{4}{3} * \pi * (0.25m)^3\\ \\V = \frac{4}{3} * \pi * 0.015625m^3\\\\V = 0.0654 m^3\)

Now, we calculate the mass of the water; using the expression above.

\(Density = \frac{Mass}{Volume}\\Mass = Density * Volume\\\)

We substitute in our values

\(Mass = 1000kg/m^3 \ *\ 0.0654m^3\\\\Mass = 65.4kg\)

Hence, the mass of the water in spherical tank is 65.4kg.

Next we calculate the Weight which is expressed as;

\(Weight = mass\ *\ Acceleration\ of\ gravity\)

Where acceleration of gravity \(g = 9.8m/s^2\)

We substitute in our values

\(Weight = 65.4kg * 9.8m/s^2\\\\Weight = 640.8kgm/s^2\\\\Weight = 640.8N\)

Therefore, the weight of the water in spherical tank is 640.8 Newtons.

The force in each of the supporting cables DA, DB, and DC is 10/3 lb.

To determine the force in the supporting cables DA, DB, and DC, we need to consider the weight of the bucket and its contents and the angles at which the cables are supporting it. Let's assume that the bucket is being supported by three cables, each at an angle of 120 degrees from each other.

First, we need to calculate the weight of the bucket and its contents. Let's call this weight "W". We know that the total weight of the bucket and its contents is 20 lb, so:

W = 20 lb

Next, we need to find the vertical component of the weight, which is the weight that is being supported by the cables. This is given by:

Vertical component of weight = W * cos(60 degrees)

where cos(60 degrees) = 0.5.

So, the vertical component of the weight is:

Vertical component of weight = W * 0.5 = 10 lb

Now, we can use the principle of equilibrium to find the forces in the cables. The principle of equilibrium states that the sum of the forces acting on an object in equilibrium (i.e. not moving) is zero.

Let's assume that the tension in cable DA is T1, the tension in cable DB is T2, and the tension in cable DC is T3. Then, we can write:

T1 + T2 + T3 = 10 lb

We also know that the tensions in the cables are equal, since the bucket is being supported at equal angles. So:

T1 = T2 = T3

Substituting this into the equation above, we get:

3T1 = 10 lb

So:

T1 = T2 = T3 = 10/3 lb

Therefore, the force in each of the supporting cables DA, DB, and DC is 10/3 lb.

Static Friction and Kinetic Friction

Recall from the previous chapter that friction is a force that opposes motion, and is around us all the time. Friction allows us to move, which you have discovered if you have ever tried to walk on ice.

There are different types of friction—kinetic and static. Kinetic friction acts on an object in motion, while static friction acts on an object or system at rest. The maximum static friction is usually greater than the kinetic friction between the objects.

Imagine, for example, trying to slide a heavy crate across a concrete floor. You may push harder and harder on the crate and not move it at all. This means that the static friction responds to what you do—it increases to be equal to and in the opposite direction of your push. But if you finally push hard enough, the crate seems to slip suddenly and starts to move. Once in motion, it is easier to keep it in motion than it was to get it started because the kinetic friction force is less than the static friction force. If you were to add mass to the crate, (for example, by placing a box on top of it) you would need to push even harder to get it started and also to keep it moving. If, on the other hand, you oiled the concrete you would find it easier to get the crate started and keep it going.

Figure 5.33 shows how friction occurs at the interface between two objects. Magnifying these surfaces shows that they are rough on the microscopic level. So when you push to get an object moving (in this case, a crate), you must raise the object until it can skip along with just the tips of the surface hitting, break off the points, or do both. The harder the surfaces are pushed together (such as if another box is placed on the crate), the more force is needed to move them.

The energy stored in the given lithium-ion battery is 4.032 × 10⁴ Joules.

To calculate the energy stored in the lithium-ion battery, we can use the formula:

Energy (Joules) = Voltage (V) × Charge (Coulombs)

First, we need to convert the capacity of the battery from milliampere-hours (mA·hr) to coulombs (C).

Since 1 Coulomb is equal to 3600 Coulombs (1 A·hr = 3600 C), we can convert 700 mA·hr to coulombs:

700 mA·hr = 700 × (1/1000) A × 1 hr × 3600 s/hr

= 2.52 × 10³ C

Now, we can calculate the energy stored in the battery:

Energy (Joules) = 16 V × 2.52 × 10³ C

= 4.032 × 10⁴ J

Therefore, the energy stored in the given lithium-ion battery is 4.032 × 10⁴ Joules in engineering notation with units using a standard SI prefix and the appropriate SI unit symbol.

a. a = 12 is the solution to the given congruence relation. b. the positive integers less than 12 that are relatively prime to 12 are 1, 5, 7, and 11.

(a) The main answer: The integer a that satisfies a ≡ -15 (mod 27) is 12.

To find the value of a, we need to consider the congruence relation a ≡ -15 (mod 27). This means that a and -15 have the same remainder when divided by 27.

To determine the value of a, we can add multiples of 27 to -15 until we find a number that falls within the range of {0, 1,..., 26}. By adding 27 to -15, we get 12. Therefore, a = 12 is the solution to the given congruence relation.

(b) The main answer: The positive integers less than 12 that are relatively prime to 12 are 1, 5, 7, and 11.

Supporting explanation: Two integers are relatively prime if their greatest common divisor (GCD) is 1. In this case, we are looking for positive integers that have no common factors with 12 other than 1.

To determine which numbers satisfy this condition, we can examine each positive integer less than 12 and calculate its GCD with 12.

For 1, the GCD(1, 12) = 1, which means it is relatively prime to 12.

For 2, the GCD(2, 12) = 2, so it is not relatively prime to 12.

For 3, the GCD(3, 12) = 3, so it is not relatively prime to 12.

For 4, the GCD(4, 12) = 4, so it is not relatively prime to 12.

For 5, the GCD(5, 12) = 1, which means it is relatively prime to 12.

For 6, the GCD(6, 12) = 6, so it is not relatively prime to 12.

For 7, the GCD(7, 12) = 1, which means it is relatively prime to 12.

For 8, the GCD(8, 12) = 4, so it is not relatively prime to 12.

For 9, the GCD(9, 12) = 3, so it is not relatively prime to 12.

For 10, the GCD(10, 12) = 2, so it is not relatively prime to 12.

For 11, the GCD(11, 12) = 1, which means it is relatively prime to 12.

Therefore, the positive integers less than 12 that are relatively prime to 12 are 1, 5, 7, and 11.

The function is \(-\sin x\) and the constant of integration is \(C = - 1\).

Explanation:

The resultant expression is equal to the sum of a constant multiplied by the integral of a given function and an integration constant. That is:

\(a = k\cdot \int\limits {f(x)} \, dx + C\)

Where:

\(k\) - Constant, dimensionless.

\(C\) - Integration constant, dimensionless.

By comparing terms, \(k = 2\), \(C = -1\) and \(\int {f(x)} \, dx = \cos x\). Then, \(f(x)\) is determined by deriving the cosine function:

\(f(x) = \frac{d}{dx} (\cos x)\)

\(f(x) = -\sin x\)

The function is \(-\sin x\) and the constant of integration is \(C = - 1\).

In the radio communication system, multipath is the propagation phenomenon that causes diffusion or reflection in multiple different directions of a signal.

Multipath is a propagation mechanism that impacts the propagation of signals in radio communication. Multipath results in the transmission of data to the receiving antenna by two or more paths. Diffusion and reflection are the causes that create multiple paths for the signal to be delivered.

Diffraction occurs when a signal bends around sharp corners; while reflection occurs when a signal impinges on a smooth object. When a signal is received through more than one path because of the diffraction or reflection, it creates phase shifting and interference of the signal.
