When an iron bar is placed within the coils of a solenoid, it becomes a magnet.

<h2>Answer:</h2>

<u>The correct answer is option C.</u><u> It becomes a magnet</u>

<h2>Explanation:</h2>

A solenoid is a cylindrical coil wound from a wire. When an electric current is passed through the solenoid, a magnetic flux is produced around the solenoid. This magnetic flux is equally distributed inside the solenoid and whenever a metal like iron is placed in the path of these magnetic lines of force, the metal becomes a magnet which in the given case is iron.

1. The resistor is located at point D.

A resistor is an element of a circuit that opposes to the flow of current through it: the value of its resistance (R) tells how much the resistor opposes to the flow of current, and the resistance is related to the voltage in the circuit (V) and the current (I) by the Ohm's law:

$V=IR$

Resistance is measured in Ohm ( $\Omega$ ), and a resistor is usually represented with a zig-zag line as the one at point D.

2. The switch is located at point B.

A switch is an element of the circuit that can be switched on and off, opening and closing the circuit, therefore allowing or not the flow of current through it. When the switch is open, no current flows; when it is closed, the current can flow through the circuit.

The symbol of a switch is represented at point B.

What do you mean by shearing stress??

lord [1]

Answer:

Shear stress, force tending to cause deformation of a material by slippage along a plane or planes parallel to the imposed stress. The resultant shear is of great importance in nature, being intimately related to the downslope movement of earth materials and to earthquakes.

the acceleration of a rocket traveling upward is given by a=(6+.02s)m/s^s, where s is in meters. Determine the rocket's velocity

NikAS [45]

Answer:

a) velocity v = 322.5m/s

b) time t = 19.27s

Explanation:

Note that;

ads = vdv

where

a is acceleration

s is distance

v is velocity

Given;

a = 6 + 0.02s

so,

$\int\limits^s_0 {a} \, ds = \int\limits^v_0 {v} \, dv\\ \int\limits^s_0 {6+0.02s} \, ds = \int\limits^v_0 {v} \, dv\\ 6s + \frac{0.02s^{2} }{2} = \frac{1}{2} v^{2} \\v = \sqrt{12s + 0.02s^{2} } .....................1 \\\\\\$

Remember that

$v = \frac{ds}{dt} \\\frac{ds}{v} = dt\\\int\limits^s_0 {\frac{ds}{\sqrt{12s+0.02s^{2} } } } \, ds = \int\limits^t_0 {} \, dt \\t= (5\sqrt{2} ) ln \frac{| [s + 300 + \sqrt{(s^{2} + 600s)} ] |}{300} .......2$

substituting s = 2km =2000m, into equation 1

v = 322.5m/s

substituting s = 2000m into equation 2

t = 19.27s
