What is the difference between Daniel and Leclanché cell

Physics
1 answer:
Thepotemich [5.8K]3 years ago
3 0

Explanation:

Leclanche cell : Leclanche cell is also known as dry cells (fig 2). It contains an electrolyte of ammonium chloride. Carbon acts as a cathode while zinc is an anode.

It consists of a zinc rod and a copper vessel (in fig 1). It can be seen that a zinc rod is put in dilute sulfuric acid which is contained in a porous pot.   Daniel cell works on the principle of the redox reaction. The electrons pass form zinc rod to wire. Then it passes to the copper rod. Thus, a current is produced.

<h2>Apartment Explosion Reported </h2>

The apartment’s explosion, reportedly caused by a gas leak, produced a violent release of gas and heat. The heat increased the temperature of the air in the room, which means an increase in the air's molecular kinetic energy.

When heat is provided then temperature increases and the molecules of substances move rapidly by increase of kinetic energy (K.E) temperature increases. It is understood that heat increases temperature.

2 kids are running down the hall at 2 m/s, one is 40kg and the other is 50kg (p=ma)
Georgia [21]

The net force acting on the two (2) kids is equal to 180 Newton.

<u>Given the following data:</u>

  • Mass of kid 1 = 40 kilogram.
  • Mass of kid 2 = 50 kilogram.
  • Acceleration = 2 m/s^2

To determine the net force acting on the two (2) kids:

First of all, we would calculate the total mass of the two (2) kids:

Total\;mass = 50+40

Total mass = 90 kg.

<h3>How to calculate net force.</h3>

In this exercise, you're required to calculate the magnitude of the net force that is acting on these two (2) kids running down the hall. Thus, we would apply Newton's Second Law of Motion.

Mathematically, Newton's Second Law of Motion is given by this formula;

Net\;force = mass \times acceleration

Substituting the given parameters into the formula, we have;

Net\;force = 90 \times 2

Net force = 180 Newton.

A wildlife researcher is tracking a flock of geese. the geese fly 3.5 km due west, then turn toward the north by 40 ∘ and fly an
kaheart [24]

To solve this problem, we can use the cosine formula for calculating the length of the displacement:

c^2 = a^2 + b^2 – 2 a b cos θ

 

where c is the displacement, a = 3.5 km, b = 4.5 km, and θ is the angle inside the triangle

 

Since the geeze turned 40° from west to north, so the angle inside the triangle must be:

θ = 180 – 40 = 140°

 

c^2 = 3.5^2 + 4.5^2 – 2 (3.5) (4.5) cos 140

c^2 = 56.63

c = 7.53 km

 

<span>So the magnitude of the displacement is 7.53 km</span>

If two identical cars are traveling at different velocities, which car has the greatest momentum ​
vodomira [7]

Answer:

The one with highest velocity

Explanation:

The momentum of an object is given by

p=mv

where

m is the mass of the car

v is the velocity of the car

In this problem, we have two identical cars: identical means they have same mass, so

m_1 = m_2 = m

The momentum of car 1 is

p_1 = mv_1

while the momentum of car 2 is

p_2 = mv_2

By comparing the two expressions, we see that the car with greatest momentum is the one with highest velocity, since the mass is the same.
