The correct statement regarding collision theory is:

Higher temperature increases the frequency of effective collision.

According to collision theory, for a chemical reaction to occur, molecules must collide with sufficient energy and proper orientation. Increasing the temperature increases the kinetic energy of the molecules, leading to higher collision frequencies and a greater likelihood of successful collisions. Therefore, higher temperatures increase the frequency of effective collisions and can accelerate the reaction rate.

The other statements are not entirely accurate:

1. Not all molecular collisions result in chemical reactions. The collisions must occur with sufficient energy and proper orientation for a reaction to take place.

2. The reaction rates do not always decrease when reactant concentrations decrease. In some cases, the reaction rate may depend on the concentration of certain reactants, but it is not a general rule.

3. Catalysts speed up reactions by providing an alternative reaction pathway with lower activation energy, allowing the reaction to proceed at a faster rate. Catalysts do not increase the kinetic energy of reactants.

Hence, The correct statement regarding collision theory is Higher temperature increases the frequency of effective collision.

Temperature at state 1 \(T_{2}\) is 650 degree cel. This is equal to the 923 K.

To know the mass flow rate use the idol gas equation. Idol gas equation for a substance can be given as,

\(PV=nRT\)

Rewrite this equation for \(n\),

\(n=\dfrac{PV}{RT}\)

Put the value of known variable from the question,

\(n=\dfrac{100\times\dfrac{850}{60} }{0.287\times 313}\)

\(n=15.77\)

Thus the value of n is 15.77 kg/sec.

In Bryon cycle we know that the processes 1-2 and 3-4 are isotropic. Hence,

\(T_{2} =T_{1}\left (1+ \dfrac{r_{p}^{\dfrac{\gamma-1}{\gamma}-1} }{c_{v} } \right )\)

\(T_{2} =313\left (1+ \dfrac{16^{\dfrac{1.35-1}{1.35}-1} }{0.821 } \right )\)

\(T_{2} =700\)

Temperature at state 3 is,

\(T_{3} =\dfrac{T_4}{1+c_p(r_p^{\dfrac{\gamma-1}{\gamma}-1}-1)}\)

Put the value in above equation we get,

\(T_3=1682\)

\(W=mc_p(T_i{n}-T_{out})\)

\(W=mc_p(T_3-T_2-T_4+T_{1})\)

\(W=15.77\times1.109(1682-700-923+313)\)

\(W=65\)

Thus the net power output is 70 watt.

\(r_b=\dfrac{T_2-T_1}{T_3-T_4}\)

\(r_b=\dfrac{700-313}{1682-923}\)

\(r_b=0.51\)

Hence the back work ratio is 0.51.

\(\eta=\dfrac{W}{Q_{in}}\)

\(\eta=\dfrac{65}{mc_p(T_3-T_2)}\)

\(\eta=0.379\)

Hence, for the given problem the net power output is 70 watt,the back work ration is 0.51, and the thermal efficiency is 0.379.

When the distance between two point charges is increased by a factor of 2, the force they exert on each other decreases to 1/4 of the original force. The relation is governed by the Coulomb's Law.

According to Coulomb's Law, the force between two point charges is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. In this scenario, if the distance between the charges is increased by a factor of 2, it means that the new distance is twice the original distance.

Since the force is inversely proportional to the square of the distance, doubling the distance will result in the force becoming 1/4 of the original force. Mathematically, this can be represented as follows:

\(F' = F / (2^2)\)

\(F' = F / 4\)

Therefore, the force between the two charges will become 1/4 (or 25%) of the original force when the distance between them is increased by a factor of 2.

B They react with all metals producing hydrogen.

Answer:

The new volume is the same as the initial volume, i.e. 20 mL.

Explanation:

To find the new volume we can use the Ideal gas law:

\( PV = nRT \)

Where:

P: is the pressure

V: is the volume

R: is the gas constant

n: is the number of moles

T: is the temperature

Initially, we have:

\( \frac{P_{i}V_{i}}{T_{i}} = nR \)    (1)

In the final state:  

\( \frac{P_{f}V_{f}}{T_{f}} = nR \)    (2)

By equating equation (1) and (2) we have:          

\( \frac{P_{i}V_{i}}{T_{i}} = \frac{P_{f}V_{f}}{T_{f}} \)  

\( \frac{P_{i}V_{i}}{T_{i}} = \frac{2P_{i}V_{f}}{2T_{i}} \)  

\(V_{f} = \frac{2T_{i}*P_{i}*V_{i}}{T_{i}*2P_{i}}\)

\( V_{f} = V_{i} \)

\( V_{f} = 20.0 mL \)

Therefore, the new volume is the same as the initial volume, i.e. 20 mL.

To calculate the final velocity after the collision between the two celestial bodies, we need to apply the principle of conservation of momentum. The final velocity will depend on the masses and initial velocities of the bodies.

According to the principle of conservation of momentum, the total momentum before the collision is equal to the total momentum after the collision. The momentum of an object is given by the product of its mass and velocity.

Let's denote the mass of the first celestial body as m1 (55 kg) with a velocity of v1 (565 m/s), and the mass of the second celestial body as m2 (40 kg) with a velocity of v2 (-613 m/s, since it is moving west).

The total momentum before the collision is given by:

Initial momentum = m1 * v1 + m2 * v2

To find the final velocity, we need to equate the initial momentum to the total momentum after the collision:

m1 * v1 + m2 * v2 = (m1 + m2) * vf

Where vf represents the final velocity.

Solving this equation for vf, we get:

vf = (m1 * v1 + m2 * v2) / (m1 + m2)

Substituting the given values, we have:

vf = (55 kg * 565 m/s + 40 kg * -613 m/s) / (55 kg + 40 kg)

vf = (-2905 kg·m/s) / (95 kg)

vf ≈ -30.58 m/s

Therefore, the final velocity after the collision is approximately -30.58 m/s. The negative sign indicates that the final velocity is in the opposite direction of the initial velocities.

The thickness of the air column above 1 m² of the Earth's surface that would have a weight of about 100,000 N is equal to 8,680.56 meters assuming the density of air remained constant at 1.2 kg/m³.

If the density of air were a constant 1.2 kg/m³ throughout the atmosphere, we can calculate the thickness of the air column that would have a weight of about 100,000 N on an area of 1 m².

The weight of the air column can be calculated using the formula:

Weight = density × volume × gravitational acceleration

We can rearrange the formula to solve for the volume:

\(\text{{Volume}} = \frac{{\text{{Weight}}}}{{\text{{density}} \times \text{{gravitational acceleration}}}}\)

Substituting the given values:

Weight = 100,000 N

Density = 1.2 kg/m³

Gravitational acceleration (g) ≈ 9.8 m/s²

\(Volume = \frac{100000 N}{(1.2 kg/m^3) \times (9.8 m/s^2)}\)

Volume ≈ 8,680.56 m³

Therefore, if the density of air were a constant 1.2 kg/m³, the thickness of the air column above 1 m² of the Earth's surface that would have a weight of about 100,000 N is approximately 8,680.56 meters.

(b) The displacement of the object in time interval between t = 0 s and t = 10 s is 60 m.

(a) The distance travelled by the object is calculated from the total area of the curve.

total distance = area of triangle 1 + area of triangle 2 + area of rectangle.

total distance = (¹/₂ x base x height)₁ +  (¹/₂ x base x height)₂ + length x width

total distance = (¹/₂ x 6 s x 20 m/s) +  (¹/₂ (8 - 6) 20) + (10 - 0)(10 - 8)

total distance =  60 m + 20 m + 20 m

total distance = 100 m

(b) The displacement of the object in time interval between t = 0 s and t = 10 s is calculated as follows;

displacement = final position - initial position

displacement =  (¹/₂ x base x height)₁ +  (¹/₂ x base x height)₂ + length x width

displacement = (¹/₂ x 6 s x 20 m/s) +  (¹/₂ (8 - 6) (-20)) + (10 - 0)(10 - 8)
