Hey there! :D

To some extent, all moving parts produce friction. It can be very small or minimal, but all parts produce some form of friction.

This is true.

I hope this helps!

Storm clouds being formed will most likely occur in this scenario.

<h3>What are Storm clouds?</h3>

These are formed during the process of convection in which heat and moisture is transported upward into the atmosphere.

We were told that the weather is warm and cold air will enter the region which means that it will replace the heat and moisture as they move upwards thereby resulting in the formation of storm clouds.

The radioactive decay obeys first order kinetics

the rate law expression for radioactive decay is

$ln\frac{[A_{0}]}{[A_{t}]}=kt$

Where

A0 = initial concentration

At = concentration after time "t"

t = time

k = rate constant

For first order reaction the relation between rate constant and half life is:

$k=\frac{0.693}{t_{\frac{1}{2} } }$

Let us calculate k

k = 0.693 / 72 = 0.009625 years⁻¹

Given

At = 0.25 A0

$ln(\frac{A0}{0.25A0})=0.009625 X time$

time = 144 years

So after 144 years the sample contains 25% parent isotope and 75% daughter isotopes**

Simply two half lives

What condition must be met for a battery to be rechargeable?

Neko [114]

Answer:

D. The electrochemical reaction of the battery must be reversible.

Explanation:

The batteries are based on the production of an electric flux given by a redox reaction. This reaction is spontaneous and is thermodynamically favored.

Thus, when the reactants to the reaction are finished, the flow of current stops and ends. Therefore, when current is administered from another source, the reaction changes its direction and reagents that were previously consumed begin to occur. Therefore the condition for it to be rechargeable is that the reaction can go forward or backward, that is, it is reversible.
