An ac source of period T and maximum voltage V is connected to a single unknown ideal element that is either a resistor, and ind

torisob [31]

Answer:

This satisfy the above given condition so we can say that this capacitor.

Explanation:

Let's take one by one option and check whether is wrong or right

<u>For inductor:</u>

$I=I_osin(wt-\frac{\pi }{2})$

Given that at t=T/4 ,I=0 and we know that

$w=\dfrac{2\pi }{T}$

So at T/4

$I=I_osin(\frac{2\pi }{T}\times \frac{T}{4}-\frac{\pi }{2})$

I=0 A

At t=T/2

$I=I_osin(\frac{2\pi }{T}\times \frac{T}{2}-\frac{\pi }{2})$

$I=I_o$

It means that this not a indutor.

<u>For capacitor:</u>

$I=I_osin(wt+\frac{\pi }{2})$

At T/4, I=0

At t=T/2

$I=I_osin(\frac{2\pi }{T}\times \frac{T}{2}+\frac{\pi }{2})$

$I= -I_o$

This satisfy the above given condition so we can say that this capacitor.

Anders suffered a shock when his electric radio dropped into the bathtub--while anders was taking a bath. Anders argued that he

blsea [12.9K]

The claim Anders is most likely to make is the failure of the manufacturer to warn about such risk.

<h3>What is a Risk?</h3>

This is defined as the possibility of something bad happening and in this case it is electric shock when dropped into the bathtub.

Anders can decide to sue for not warning against risk of electric shock when in contact with water.

. An object has a position given by ~r(t) = [3.0 m − (4.00 m/s)t]ˆı + [6.0 m − (8.00 m/s2 )t 2 ]ˆ , where all quantities are in

kupik [55]

Answer:

(c) 16 m/s²

Explanation:

The position is $r(t) = [3.0 \text{ m} - (4.00 \text{ m/s})t]\hat{i} + [6.0 \text{m} - (8.00 \text{ m/s}^2 )t^2 ]\hat{j}$ .

The velocity is the first time-derivative of <em>r(t).</em>

<em /> $v(t) = \dfrac{d}{dt}r(t) = -4.00\,\hat{i} -16t\,\hat{j}$ <em />

The acceleration is the first time-derivative of the velocity.

$a(t) = \dfrac{d}{dt} v(t) = -16\hat{j}$

Since <em>a(t)</em> does not have the variable <em>t</em>, it is constant. Hence, at any time,

$a = -16\hat{j}$

Its magnitude is 16 m/s².
