Answer:

Q=1.42 C

Explanation:

Given that

I=I_oe^{\dfrac{-t}{\tau}}

When t= 0 ,Io = 3 A

τ = Time constant = 0.5 s

I=3e^{-\dfrac{t}{\tau}}

We know that

I=\dfrac{dQ}{dt}

Q=Charge ,I =Current

Q = ∫I.dt

Given that

t= 0 to t= 3τ= 1.5 s

The charge Q

Q=\int_{0}^{1.5}3e^{-\dfrac{t}{0.5}}dt

Q=1.42 C

Therefore charge flow conductor will be 1.42 C.

PLEASE HELP ASAP!! What are 3 types of forces acting on your marshmallow (or other flying object) when it impacts it’s target? C
Alekssandra [29.7K]
•Every action has an equal and opposite reaction (the object is putting force on the target, and the target is putting an equal amount of force back)
•Am object in motion (the object) will stay in motion unless an outside force acts upon it (the Target)

And as for the third one I really don’t know, those seem to be the only two, I’m sorry. I did what a could, Hope it kinda helps :)

66 POINTS! Which is true about the four atoms shown in figures A, B, C, and D?
Butoxors [25]

Answer:

A

Explanation:

A and B are isotopes of one another but the same element

C and D are isotopes of one another but the same element

However, A and B have a different proton count than C and D, indicating different elements because the proton count is equivalent to the atomic number.
