The farmer's decision to sell produce directly to the local market is an example of vertical integration.

Vertical integration refers to the process of combining different stages of production or distribution within a single company or entity. In this case, the farmer is bypassing the intermediaries or agents who previously bought his produce and sold it to the markets. By selling directly to the local market, the farmer is integrating the production and distribution stages of the supply chain, eliminating the need for intermediaries and gaining more control over the pricing and sales of his products.

Explanation:

Given parameters:

Mass of ball  = 0.0459kg

Force  = 2380N

Time taken  = 0.001s

Unknown:

Speed of the ball afterwards  = ?

Solution:

To solve this problem, we use Newton's second law of motion:

   F = m x \(\frac{v - u}{t}\)  

F is the force

m is the mass

v is the final velocity

u is the initial velocity

t is the time taken

        2380  = 0.0459 x \(\frac{v- 0}{0.001}\)  

        0.0459v  = 2.38

                   v = 51.85m/s

Answer:

2.38

Explanation:

F = dp/dt  --> dp = F*dt ---> p = F*t if F is constant over time so

p = 2380N* 0.001 s = 2.38 kg-m/s

Answer:

The potential is  \(V_A = 9600 \ V\)

Explanation:

From the question we are told that  

   The  magnitude of the charge is  \(q_1 = 4 \mu C = 4*10^{-6} \ C\)

   The position of the charge is  \(x = + 3.0 \ m\)

   The magnitude of the second charge is  \(q_2 = -2.0 \mu C = -2.0 *10^{-6} \ C\)

   The position is  \(y_1 = - 1.0 \ m\)

     The position of point A is  \(y_2 = + 4.0 \ m\)  

Generally the electric potential  at A due to the first charge is mathematically represented as

         \(V_a = \frac{k * q_1 }{r_1 }\)

Here k is the coulombs constant with value \(k = 9*10^{9} \ \ kg\cdot m^3\cdot s^{-4} \cdot A^{-2}\)

        \(r_1\)  is the distance between first charge and a which is mathematically represented as

         \(r_1 = \sqrt{x^2 + y_2 ^2 }\)

=>      \(r_1 = \sqrt{3^2 + 4 ^2 }\)    

=>      \(r_1 = 5 \ m\)    

So

           \(V_a = \frac{9*10^9 * 4*10^{-6} }{5 }\)

      \(V_a = 7200 \ V\)

Generally the electric potential  at A due to the second charge is mathematically represented as

         \(V_b = \frac{k * q_2 }{r_2 }\)

Here k is the coulombs constant with value \(k = 9*10^{9} \ \ kg\cdot m^3\cdot s^{-4} \cdot A^{-2}\)

        \(r_2\)  is the distance between second charge and a which is mathematically represented as

         \(r_2 = y_2 - y\)

=>      \(r _2 = 4.0 - (-1.0)\)    

=>      \(r = 5 \ m\)    

So

           \(V_a = \frac{9*10^9 * -2*10^{-6} }{5 }\)

      \(V_a = -3600 \ V\)

So the net potential difference at point A  due to the charges is mathematically represented as

       \(V_n = V_a + V_b\)

=>     \(V_n = 7200 - 3600\)

=>     \(V_n = 3600 V\)

Generally the net potential difference at the origin due to both charges is mathematically represented as

     \(V_N = V_c + V_d\)

Here  

      \(V_c = \frac{k * q_1 }{x}\)

=>   \(V_c = \frac{9*10^9 * 4*10^{-6} }{3}\)

=>   \(V_c = 12000 V\)

and

              \(V_d= \frac{k * q_2 }{y}\)

=>   \(V_c = \frac{9*10^9 * -2*10^{-6} }{1}\)

=>   \(V_c =- 18000 V\)

Generally the net potential difference at the origin is  

       \(V_N = 12000 - 18000\)

=>     \(V_N = -6000\)

Generally the potential difference at A relative to zero at the origin is mathematically evaluated as

         \(V_A = V_n - V_N\)

=>      \(V_A = 3600 - (-6000)\)

=>      \(V_A = 9600 \ V\)

If the final potential difference across the 69micro -f then capacitor is 40Mf

We cannot expect simple energy conservation to hold because energy is presumably dissipated as heat in the connection wires or as radio waves while the charge oscillates during the system "settling down" to its final state (40V across the parallel pair of capacitors C and 60 F).

We anticipate that charge will be conserved. Thus, if Q is the initial charge stored on C and q 1 and q2 are the charges on the parallel pair after "settling down," then -

Q= q1+ q2

C(100V) = C(40V) + 60mf(40V)

When inspecting a roller bearing on a car for a hot box, it is important to place the temperature indicator in the correct location in order to accurately detect any issues with the bearing. In this answer, we will explain why the temperature indicator must be placed on the lower half of the cup.

A hot box, also known as an overheated bearing, occurs when the temperature of a roller bearing becomes elevated due to friction or other factors. This can cause damage to the bearing, leading to reduced performance and potentially even failure. To detect hot boxes, a temperature indicator is used to measure the temperature of the bearing.

It is recommended to place the temperature indicator on the lower half of the cup for several reasons. First, the lower half of the cup typically experiences the highest temperatures due to the presence of friction in that area. By placing the temperature indicator on the lower half of the cup, it is possible to accurately measure the temperature of the bearing and detect any hot box issues.

Second, the temperature indicator will provide a more accurate reading when placed on the lower half of the cup compared to other locations, such as the outer race or the inner race. This is because the lower half of the cup is more directly exposed to the temperature of the bearing and is not affected by other factors such as temperature gradients or convection currents.

To keep an object in motion, continuous application of force is required due to the presence of opposing frictional force. Starting the object requires an initial force greater than the frictional force, and once in motion, the force applied needs to counteract the dissipative effects of friction to maintain the object's motion.

When an object is at rest or stationary, static friction opposes any applied force. To start the motion of the object, we need to apply a force greater than the static friction. Once the object is in motion, the friction that acts on it changes to kinetic friction, which is generally lower than static friction. However, kinetic friction still opposes the motion and acts as a dissipative force.

To keep the object in motion, a continuous force needs to be applied to overcome the dissipative effects of kinetic friction. This force compensates for the energy lost due to friction and ensures that the object remains in motion. If the applied force is insufficient to counteract the frictional force, the object will eventually come to a halt due to the dissipation of energy through friction.

In summary, continuous application of force is necessary to keep an object in motion as it counteracts the opposing force of friction, which dissipates energy. Without this continuous force, the dissipative effects of friction would cause the object to slow down and eventually stop.

First, we know two things:

We can also assume, because of the second thing, that all ice cubes have the same temperature.

Then, one way to know which cup has more temperature is to put one ice cube on each cup, then measure the time it takes for the cube to melt completely.

When you put the ice cube on the cup, it will start to "drain" the heat energy from the liquid. If the liquid has more temperature, more energy can the cube drain, thus faster it will change to the liquid phase.

Case 1: 1 kg of water at 10° C

Let the final temperature be T° C , where T°C < 30°C.

Heat give out by 4.4 kg of water at 30° C to come down to T°C = 4400 g × 1 calorie/g/°C × (30- T)° C = (4400× 30 - 4400 T) calorie

Heat gained to raise temperature of 1kg of water at 10° to T° = 1000 g × 1 calorie/g/°C × (T -10)° C = 1000 T - 10,000) calorie

Heat gained = Heat lost

1000 T - 10,000 = 1,32,000 - 4400 T; ==> 54 00T = 1.42,000; T = 1,42,000/5400 = 26.3° C.

In case it is 1 kg of water at 10° C mixed with 4.4 kg of water at 30° C, the final temperature of the mixture would be T = 26.3° C.

Case 2: 1 kg of ice.

Ice is essentially at its melting point/freezing point ie at 0° C.

Let the temperature of mixture = T° C

Heat required to melt 1 kg (=1000 g of ice) at 0° C to water at 0° C = 1000 g × 80 calorie/g = 80,000 calorie

Heat require to raise temperature of 1000 g of water at 0° C to water at T° C = 1000g × 1 calorie/g/°C× (T -0)° C = 1000 T calorie

Heat gained = 80,000 + 1000 T

Heat lost by 4.4 kg of water at 30° C to cool to T° C = 4400 g × 1 calorie/g /° C × ( 30 - T)° C = 1,32,000 - 4400 T

Heat gained = Heat lost

80,000 + 1,000 T = 1,32,000 -4400 T

5400 T = 52,000/5400; ==> T = 9.63°C.

In case it is ice, the temperature of the mixture is T = 9.63° C.

Explanation:

The composition of a comet compared with that of the Sun is C "Comets are made of ice and dust, while the Sun is made of gas".

Comets are small, icy bodies that originate from the outer solar system and are composed mainly of frozen water, carbon dioxide, methane, and ammonia, along with dust and small rocky particles. When a comet approaches the Sun, its icy material vaporizes, creating a glowing coma (a hazy atmosphere around the nucleus) and a tail that points away from the Sun due to the solar wind.

On the other hand, the Sun is a giant ball of hot, glowing gas, composed mainly of hydrogen (about 73% of its mass) and helium (about 25% of its mass), with trace amounts of other elements like oxygen, carbon, and iron. The Sun generates energy through nuclear fusion reactions in its core, which convert hydrogen into helium and release a tremendous amount of energy in the process.

Therefore, the composition of a comet is quite different from that of the Sun. While both objects contain some water (in the form of ice for comets and vapor for the Sun), comets are predominantly made of ice and dust, while the Sun is predominantly made of gas, with only a small amount of solid material in its core.

The voltage drop across the 18 kΩ resistor is 90 volts. This means that when a current of 5 mA flows through an 18 kΩ resistor, there is a potential difference of 90 volts across the resistor.

To calculate the voltage drop across a resistor, Ohm's Law can be applied. Ohm's Law states that the voltage (V) across a resistor is equal to the product of the current (I) flowing through it and the resistance (R) of the resistor. The formula for Ohm's Law is V = I * R.

Given:

Current (I) = 5 mA = 5 * 10^(-3) A

Resistance (R) = 18 kΩ = 18 * 10^(3) Ω

Using Ohm's Law, we can calculate the voltage drop (V):

V = I * R

= (5 * 10^(-3) A) * (18 * 10^(3) Ω)

= 90 V

The concentration of salt in water affects the specific heat capacity by changing the thermal properties of the solution, causing it to require less heat to be raised in temperature.

The specific heat capacity of water is the amount of heat required to raise the temperature of a certain mass of water by 1 degree Celsius. The concentration of salt in water affects its specific heat capacity because the presence of ions in the solution changes the thermal properties of the water.

As the concentration of salt in water increases, the specific heat capacity of the solution decreases. This is because the ions in the salt solution require less heat to be raised in temperature than pure water molecules. Additionally, the ions in the salt solution also increase the mobility of water molecules, causing them to transfer heat more efficiently and therefore, the heat energy required to raise the temperature of the solution is reduced.

It should be noted that the effect of salt concentration on specific heat capacity is small, and significant changes in specific heat capacity usually require very high salt concentrations. Nevertheless, the change in specific heat capacity can have a significant impact on the thermal dynamics of systems such as oceans, which contain high salt concentrations.
