If you want to make a strong battery, should you pair two metals with high electron affinities, low electron affinities, or a mi

zalisa [80]

A mix

Explanation:

A battery is an electrochemical cell that converts chemical energy into electrical energy. The chemical reactions in a battery ensures that current is produced.

A battery is made up of two electrodes which are the cathode and anode.
The cathode is the positive electrode and the anode is the negative one.
These electrodes are made up of metals.
Electrons moves from the anode to the cathode and current flows from cathode to anode.
At the anode oxidation occurs because electrons are produced here.
It needs to have low electron affinity.
At the cathode where reduction occurs, the electron affinity must be high.
This is the driving force for the production of electricity in electrochemical cells.

You are at an office party, a holiday party, or a gathering of friends at the home of a neighbor and you are engaged in convers

irina [24]

The correct answer is; Yes, you can be unconsciously eavesdropping.

Further Explanation:

When this occurs it is called the “The Cocktail Party Phenomenon.” Your mind can focus on one conversation that is being made and drown out all other speech and things going on around you. This makes your brain have auditory attention on one specific conversation.

The sensory hearing in the person listening to the conversation is subconsciously filtering the conversation into its own stream in the brain. This phenomenon can also detect certain words that are important to the person with a large amount of noise in the background.

This occurs in the left hemisphere of the brain in the superior temporal gyrus region.

What is the speed of an object that travels 20 meters in 4 seconds?

Iteru [2.4K]

Given:-

Distance covered by the particle (s) = 20 m
Time taken (t) = 4 seconds

To Find: Speed of it.

We know,

v = s/t

where,

v = Speed,
s = Distance &
t = Time taken.

Putting the values,

v = (20 m)/(4 s)

→ v = 5 m/s (Ans.)

A piece of taffy slams into and sticks to an identical piece of taffy at rest. The momentum of the combined pieces after the col

Marina CMI [18]

Answer:

D) 50%

Explanation:

According to conservation of momentum:

$m_{1} v_{1i} + m_{2} v_{2i} = m_{1} v_{1f} + m_{2} v_{2f}$

Assuming that the second taffy started at rest, both pieces have the same mass and that they combined after the collision, their final velocity is:

$m v_{1i} = (m+m) v_{f}\\v_{f} = 0.5 v_{1i}$

The initial kinetic energy of the system is:

$E_{ki} = \frac{m*v_{1i}^2}{2}$

Since the second taffy was not moving, it had no kinetic energy at first.

The initial kinetic energy of the system is:

$E_{kf} = \frac{2m*v_{f}^2}{2}\\E_{kf} = \frac{2m*(0.5v_{1i})^2}{2}\\E_{kf} = \frac{0.5m*v_{1i}^2}{2}$

The percentage of kinetic energy that becomes heat is given by:

$H=1 - \frac{E_{kf}}{E_{ki}}\\H=1 - \frac{\frac{0.5m*v_{1i}^2}{2}}{\frac{m*v_{1i}^2}{2}}\\\\H=1- 0.5 = 0.5$

THerefore, 50% of the kinetic energy becomes heat
