A conductor carries a current that is decreasing exponentially with time. The current is modeled as I = I0e−t/τ,where I0= 4.00 A

Whitepunk [10]

Answer:

Explanation:

Io = 4 A

τ = 0.60 s

The equation of current is given by

$I = I_{0}e^{\frac{-t}{\tau }}$

Current is defined as the rate of charge flows through the conductor

So, $\frac{dq}{dt} = I_{0}e^{\frac{-t}{\tau }}$

$\int_{0}^{q} dq = \int_{0}^{3}I_{0}e^{\frac{-t}{\tau }}dt$

$q = -4\tau \left ( e^{-\frac{t}{\tau }} \right )_{0}^{3}$

q = 2.38 C

Two identical rooms in a house are connected by an open doorway. The temperatures in the two rooms are maintained at different v

Inga [223]

Answer:

The room with the lower temperature

Explanation:

Using

PV=nRT

Since both the rooms same volume and are connected, so they will have same pressure

PV=nRT=constant

nT=Constant/R=constant

If T is more n has to be less

Thus, lower the temperature, more the number molecules.

An unbalanced force can cause an object to:

Lilit [14]

It'll speed up in the direction it's being pushed unbalanced. Or, it could slow down if applied the right amount of unbalanced power. And finally if the unbalanced push is pushed it could change the direction of it's current motion it was traveling.<span>

Hi there!

We know that:

U (Potential energy) = mgh

We are given the potential energy, so we can rearrange to solve for h (height):

U/mg = h

g = 9.81 m/s²

m = 30 g ⇒ 0.03 kg

0.062/(0.03 · 9.81) = 0.211 m
