Is Radioactive decay a way to find the relative age of a rock?<br><br> True<br> False
galina1969 [7]
To establish the age of a rock or a fossil, researchers use some type of clock to determine the date it was formed. Geologists commonly use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon, as reliable clocks to date ancient events.

Can A positively charged body attract another positively charged body​
andriy [413]

Like charges repel, unlike charges attract

Two protons will also tend to repel each other because they both have a positive charge. On the other hand, electrons and protons will be attracted to each other because of their unlike charges.

So I would say no, unless the two bodies are placed close to each other where one has much more charge than the other, then due to induction, force of attraction becomes more than the force of repulsion.

When an RL circuit is connected to a battery, which is true about its initial and final states?
zubka84 [21]

Answer:A

Explanation:

In R-L circuit current is given by

i=i_0\left [ 1-e^{\frac{-t}{L/R}}\right ]

where i=current at any time t

i_0=maximum\ current

R=resistance

L=Inductance

at t=0 e^{\frac{-t}{L/R}} approaches to 1

therefore i=i_0\left [ 1-1\right ]

i=0

when t approaches to \infty,  e^{\frac{-t}{L/R}} approaches to zero

thus i=i_0

thus we can say that initially circuit act as broken wire with zero current

and it increases exponentially with time and act as ordinary connecting wire
