As the temperature increases the number of effective collisions between reacting particles in a chemical reaction
Reil [10]
Answer: option A) initially increases, then decreases.

Justification:

The increase of the rate of effective collisions among particles as the temperature increases is explained by the collision theory in virtue of the increase of the kinetic energy.

This is, as the temperature increase so the kinetic energy increase and the higher the kinetic energy the greater the number of collisions and the greater the chances that this energy overcome the activation energy (the energy needed to start the reaction).

Now, as the reaction progress the number of reactants particles naturally decrease (some of them have been converted into product) so this lower number of particles means lower concentration which means lower collisions and, thereafter, a decrease in the reaction rate.

With the switch closed, how does the voltage across the 20-ω resistor compare to the voltage across the 10-ω resistor?
jasenka [17]
In electricity, the most famous and basic equation is the Ohm's Law which relates the parameters voltage, current and resistance. One form of this law as written in equation is V = IR, where V is the voltage in volts, I is the current in amperes and R is the resistance in ohms. These parameters depends in the arrangements, whether it's series or parallel.

In a series connection, the voltage is greater across a high-resistance resistor. Therefore, the voltage is much greater for the 20-ohm resistor. However,if it is a parallel circuit, the voltage is just the same for both resistors.

In three to five sentences, identify two components of the control subsystem of a vehicle, and use them to explain why driving c
vredina [299]

A car is built from various subsystems. If these subsystems are not working properly it is dangerous because it can cause a serious traffic accident.

<h3>What subsystems do cars have?</h3>

When you're testing the build of a car, you have to check its many subsystems:

  • the battery
  • the engine
  • the cabin
  • the thermal-management system
  • the gearbox
  • the chassis
  • the suspension

<h3>Why is a car with damaged subsystems dangerous?</h3>

The subsystems of a car are very important components that allow the proper functioning of the car. These subsystems work synchronously making the car work properly.

However, if one of these subsystems is not working properly it could cause a malfunction that could lead to a traffic accident.

By what factor is the self-inductance of an air solenoid changed if its length and number of coil turns are both tripled
fredd [130]

Answer:

The new self inductance is 3 times of the initial self inductance.

Explanation:

The self inductance of a solenoid is given by :

L=\dfrac{\mu_oN^2 A}{L}

Where

N is number of turns per unit length

A is area of cross section

l is length of solenoid

If length and number of coil turns are both tripled,

l' = 3l and N' = 3N

New self inductance is given by :

L'=\dfrac{\mu_oN'^2 A}{L'}\\\\=\dfrac{\mu_o(3N)^2 A}{3L}\\\\=3\dfrac{\mu_oN^2 A}{L}\\\\=3L

So, the new self inductance is 3 times of the initial self inductance.
