A 9 V battery produces a current of 18 amps. What is the resistance?

artcher [175]

<h2> $\bf{ \underline{Given:- }}$ </h2>

$\sf• \: Battery \: Voltage \: (V) = 9 \: v$

$\sf• \: Current \: (I) = 18 \: Amps.$

$\\$

<h2> $\bf{ \underline{To \: Find :- }}$ </h2>

$\sf• \: The \: Resistance.$

$\\$

$\huge\bf{ \underline{Solution :- }}$

$\bf \red{ \bigstar{ \: Formula \: of \: Resistance \: (R) = \frac{V}{I}}}$

$\rightarrow \sf R = \frac{9}{18}$

$\rightarrow \sf R = \frac{1}{2}$

$\rightarrow \sf R = 0.5$

$\\$

<h3> $\bf \purple{Therefore, \: the \: \: resistance \: \: is \: \: 0.5 \: Ω \: .}$ </h3>

Consider the following four objects: a hoop, a solid sphere, a flat disk, a hollow sphere. Each of the objects has mass M and ra

Svetlanka [38]

Answer:

Hoop.

Explanation:

The angular acceleration performed at a given torque:

$\alpha = \frac{\tau}{I}$

The moments of inertia of each element are described below:

Hoop

$I = M\cdot R^{2}$

Solid sphere

$I = \frac{2}{5}\cdot M \cdot R^{2}$

Flat disk

$I = \frac{1}{2}\cdot M \cdot R^{2}$

Hollow sphere

$I = \frac{2}{3}\cdot M \cdot R^{2}$

The greater the moment of inertia, the greater the torque to obtain the same angular acceleration. Therefore, the hoop requires the largest torque to receive the same angular acceleration.

If a pebble is being transported in a stream by rolling, how does the velocity of it compare to the velocity of the stream?

AleksandrR [38]

Streams carry sediment, like pebbles, in their flows. The pebbles can be in a variety of locations in the flow, depending on it's size, the balance between the upwards velocity on the pebble (drag and lift forces), and it's settling velocity.
