Answer:
Known as automatic tire chains and sometimes referred to by brand names like Onspot or Insta-Chain, these chains essentially hang listlessly from the vehicle's suspension until inclement weather arrives. When that happens, a driver can flip a switch that will lower the chains so they hang in front of the back tires.

Answer:
A pendulum works by converting energy back and forth, a bit like a rollercoaster ride. When the bob is highest (furthest from the ground), it has maximum stored energy (potential energy). ... So as the bob swings (oscillates) back and forth, it repeatedly switches its energy back and forth between potential and kinetic.
I believe the answer is B: UV
Newton's law is all about motion
Answer : The time taken for the concentration will be, 7.98 seconds
Explanation :
First order reaction : A reaction is said to be of first order if the rate is depend on the concentration of the reactants, that means the rate depends linearly on one reactant concentration.
Expression for rate law for first order kinetics is given by :
![k=\frac{2.303}{t}\log\frac{[A]_o}{[A]}](https://tex.z-dn.net/?f=k%3D%5Cfrac%7B2.303%7D%7Bt%7D%5Clog%5Cfrac%7B%5BA%5D_o%7D%7B%5BA%5D%7D)
where,
k = rate constant = 
t = time taken for the process = ?
![[A]_o](https://tex.z-dn.net/?f=%5BA%5D_o)
= initial concentration = 0.860 M
![[A]](https://tex.z-dn.net/?f=%5BA%5D)
= concentration after time 't' = 0.260 M
Now put all the given values in above equation, we get:
Therefore, the time taken for the concentration will be, 7.98 seconds
