Answer:

The resultant force will be 5 N in the South West Direction.

Explanation:

If we have two vectors A and B, their resultant is:

\(\boxed{ \mathsf{Resultant = A^2+B^2+2AB\:cos(\theta)}}\)

\(\theta\) is the angle between A and B

Since, Force is a vector quantity, the answer to he given diagram will be thought out by Vector Laws of Addition.

6N and 9N are in opposite directions, so their resultant will simply be their difference, and it will be pointing in the direction of the vector with larger magnitude.

= 9 - 6

= 3 N

Now, we have two vectors. one of magnitude 4N pointing towards West and the other of magnitude 3N pointing towards South.

It's magnitude will be equal to \(\mathsf{\red{ \sqrt{4^{2} +3^{2} } }}\)

(as cos90=0, we're left with the sum of the squares of the two vectors)

= 5N

Therefore, the resultant force will be 5N towards the South-West.

Both the initial amount and the kind of gas play a role.  However, the pressure and the quantity of gas present also have a role in this relationship.

Charles' Law states that a gas's volume is directly proportionate to its temperature. However, the pressure and the quantity of gas present also have a role in this relationship. Hence, we would need to know the starting volume, pressure, and number of moles of a gas sample in order to calculate its volume at 50.0 °C. The type of gas would also be a role in deciding its final volume at 50.0 °C because different gases behave differently at various temperatures.  Ideal gas perfectly obeys the gas law.

Answer:

The centripetal force on body 2 is 8 times of the centripetal force in body 1.

Explanation:

Body 1 has a mass m, and its moving in a circle with a radius r at a speed v. The centripetal force acting on it is given by :

\(F=\dfrac{mv^2}{r}\)

Body 2 has a mass 2m and its moving in a circle of radius 4r at a speed 4v. The centripetal force on body 2 is :

\(F'=\dfrac{2m\times (4v)^2}{4r}\\\\F'=\dfrac{2m\times 16v^2}{4r}\\\\F'=8\dfrac{mv^2}{r}\\\\F'=8F\)

So, the centripetal force on body 2 is 8 times of the centripetal force in body 1.

The force needed to hold the ball completely submerged is equal to the weight of the fluid displaced by the ball.

Force = Weight

To determine the force needed to hold the ball completely submerged, we can use the concept of buoyancy.

The buoyant force acting on an object submerged in a fluid is equal to the weight of the fluid displaced by the object.

1. First, calculate the volume of the ball. The formula for the volume of a sphere is V = (4/3)πr³, where r is the radius of the ball.

Since the diameter is given as 4.20 cm, the radius is half of the diameter, which is 2.10 cm or 0.021 m. Substitute this value into the formula to find the volume.

V = (4/3)π(0.021 m)³

2. Next, convert the average density of the ball from g/cm³ to kg/m³. Since 1 g/cm³ is equal to 1000 kg/m³,

multiply the average density by 1000.

Average density = 0.0837 g/cm³ * 1000 kg/m³ = 83.7 kg/m³

3. Use the volume and density to calculate the weight of the fluid displaced by the ball.  

The weight can be calculated using the formula weight = mass * gravitational acceleration,

where the mass is equal to the volume times the density.

Weight = (Volume of the ball) * (Average density of the ball) * (Gravitational acceleration)

4. The gravitational acceleration is approximately 9.8 m/s².

Substitute the values into the formula and calculate the weight.

Weight = (V) * (83.7 kg/m³) * (9.8 m/s²)

5. Finally, the force needed to hold the ball completely submerged is equal to the weight of the fluid displaced by the ball.

Force = Weight

Substitute the weight calculated in the previous step to find the force needed to hold the ball completely submerged.

The work done in one stroke is 96.5 joules and the average force exerted on the piston, neglecting friction and gravitational force, is 86.6 Newtons.

(a) To find the work done in one stroke of the hand-driven tire pump, we need to calculate the volume of air displaced by the piston, which can be found using the formula V = πr^2h, where r is the radius of the piston (which is half the diameter), h is the stroke length, and π is a constant.

So, the volume of air displaced in one stroke is V = π(2.1/2)^2(38) = 469.8 cm^3.

Next, we can calculate the work done using the formula W = Fd, where F is the force exerted on the piston and d is the distance traveled by the piston. Since the force is equal to the gauge pressure multiplied by the area of the piston, we have:

W = (2.6×10^5 N/m^2) × π(2.1/2)^2 × 0.38 m = 96.5 J

(b) To find the average force exerted on the piston, we can rearrange the formula F = PA to solve for F, where P is the gauge pressure and A is the area of the piston. Thus:

F = PA = (2.6×10^5 N/m^2) × π(2.1/2)^2 = 86.6 N

The work done in one stroke is approximately 34.8 Joules.

The average force exerted on the piston is approximately 89.9 Newtons.

(a) The work done is given by the formula:

css

Copy code

W = P * V

where P is the pressure and V is the volume.

The volume of a cylinder (which is the shape of the piston) is given by:

V = π * r² * h

where r is the radius of the base of the cylinder (half the diameter) and h is the height of the cylinder (or the stroke). Here, r = 1.05 cm = 0.0105 m and h = 38 cm = 0.38 m.

Let's calculate the volume first:

V = π * (0.0105 m)² * (0.38 m) = 0.000134 m³

Now we can calculate the work:

W = (2.6×10^5 N/m²) * (0.000134 m³) = 34.8 J

So, the work done in one stroke is approximately 34.8 Joules.

(b) The average force exerted on the piston is given by the formula:

F = P * A

where P is the pressure and A is the area of the base of the piston. The area of a circle is given by:

A = π * r²

So,

A = π * (0.0105 m)² = 0.000346 m²

Now we can calculate the force:

F = (2.6×10^5 N/m²) * (0.000346 m²) = 89.9 N

So, the average force exerted on the piston is approximately 89.9 Newtons.

Given information: The average method reports the following unit data for the forming department. Units completed in the forming department are transferred to the painting department. Production cost information for the forming department follows.

Direct materials:
Units completed during the period = 45,000 units
Ending work in process inventory = 5,000 units
Direct materials cost = $202,500

Conversion costs:
Units completed during the period = 45,000 units
Ending work in process inventory = 5,000 units
Conversion cost = $189,000

a. Calculation of equivalent units of production for both direct materials and conversion for the forming department:
Equivalent units of production = Units completed during the period + (Ending work in process inventory * Degree of completion)
Direct materials:
Equivalent units of production = 45,000 + (5,000 * 50%) = 47,500 units

Conversion costs:
Equivalent units of production = 45,000 + (5,000 * 60%) = 48,000 units

b. Calculation of the cost per equivalent unit of production for both direct materials and conversion for the forming department:
Cost per equivalent unit of production = Total cost for the period / Equivalent units of production

Direct materials:
Cost per equivalent unit of production = $202,500 / 47,500 units = $4.26 per unit

Conversion costs:
Cost per equivalent unit of production = $189,000 / 48,000 units = $3.94 per unit

c. Calculation of the cost assigned to the forming department's output using the weighted average method:
Total cost = Cost of units transferred out + Cost of ending work in process inventory
Cost of units transferred out = Number of units transferred out * Cost per equivalent unit of production
Cost of ending work in process inventory = Number of units in ending work in process inventory * Cost per equivalent unit of production

Direct materials:
Cost of units transferred out = 40,000 * $4.26 per unit = $170,400
Cost of ending work in process inventory = 5,000 * $4.26 per unit = $21,300
Total cost = $170,400 + $21,300 = $191,700

Conversion costs:
Cost of units transferred out = 40,000 * $3.94 per unit = $157,600
Cost of ending work in process inventory = 5,000 * $3.94 per unit = $19,700

When you push a pencil off your desk, the energy transformation that takes place is that potential energy transforms into kinetic energy.

The correct answer to the given question is option C.

Potential energy is the energy stored within an object because of its position or configuration.

In this scenario, the pencil has potential energy because of its elevated position on the desk. When the pencil is pushed off the desk, it begins to move, which means that it has kinetic energy. Kinetic energy is the energy of motion.

As the pencil falls off the desk, its potential energy is transformed into kinetic energy, which is the energy that results from its motion. The faster the pencil falls, the greater its kinetic energy will be because kinetic energy is directly proportional to the square of an object's velocity.

Therefore, when you push a pencil off your desk, the potential energy that it has because of its elevated position is transformed into kinetic energy as it falls towards the ground.

The given series, 1 + 7n Σ 57 n = 1, is divergent because the terms in the series continue to increase without bounds, the sum of the series also increases indefinitely.

To determine the convergence or divergence of the series, we can analyze its behaviour as n approaches infinity. The series can be written as Σ(1 + 7n*57) for n = 1 to infinity. By simplifying the expression, we have Σ(399n + 1) for n = 1 to infinity.

As n increases, the summand of the series grows linearly with a coefficient of 399. Since the coefficient is nonzero and positive, the series will diverge. This means that the sum of the series will not approach a finite value as n tends to infinity.

Therefore, the given series is divergent, and we cannot find its sum. It is important to note that a divergent series does not have a finite sum. Therefore, the sum of the given series is "DIVERGES."

The electric field strength at a distance of 1.20 m on the x-axis is -1.5 × 10⁴ N/C.

To find the electric field strength at a distance 1.20 m on the x-axis, we can use Coulomb's law:

\($$F=k\frac{q_1q_2}{r^2}$$\)

where F is the force between two charges, q1 and q2 are the magnitudes of the charges, r is the distance between the charges, and k is the Coulomb constant.For a single point charge q located at the origin of the x-axis, the electric field E at a distance r is given by:

\($$E=\frac{kq}{r^2}$$\)  where k is the Coulomb constant.

So, let's calculate the electric field due to each charge separately and then add them up:

For the +2.0 C charge at x = 0, the electric field at a distance of 1.20 m is:\($$E_1=\frac{kq_1}{r^2}=\frac{(9\times10^9)(2.0)}{(1.2)^2}N/C$$\)

For the -3.0 C charge at x = 0.40 m, the electric field at a distance of 1.20 m is:

\($$E_2=\frac{kq_2}{r^2}\)

\(=\frac{(9\times10^9)(-3.0)}{(1.20-0.40)^2}N/C$$\)

The negative sign indicates that the direction of the electric field is opposite to that of the positive charge at x = 0.

To find the net electric field, we add the two electric fields\(:$$E_{net}=E_1+E_2$$\)

Substituting the values of E1 and E2:

\($$E_{net}=\frac{(9\times10^9)(2.0)}{(1.2)^2}-\frac{(9\times10^9)(3.0)}{(0.8)^2}N/C$$E\)

net comes out to be -1.5×10⁴ N/C.

Therefore, the electric field strength at a distance of 1.20 m on the x-axis is -1.5 × 10⁴ N/C.
