This question involves the concepts of induced emf and magnetic field.

The wire has to move at a speed of "20 m/s".

<h3>Speed of Wire</h3>

The emf induced in a current carrying conductor when it passes through a magnetic field is given by the following formula:

$E = vBl\\\\v=\frac{E}{Bl}$

where,

v = speed = ?
E = induced emf = 10 volts
B = magnetic field = 2.5 T
l = length of wire = 0.2 m

Therefore,

$v=\frac{10\ volts}{(2.5\ T)(0.2\ m)}$

v = 20 m/s

skelet666 [1.2K]

Answer:

Explanation:

a )

Moment of inertial of four masses about axis that coincides with one side :

Out of four masses . location of two masses will lie on the axis so their moment of inertia will be zero .

Moment of inertia of the two remaining masses

= m L² + m L²

= 2 mL²

b )

Axis that bisects two opposite sides

Each of the four masses will lie at a distance of L / 2 from this axis so moment of inertia of the four masses

= 4 x m x ( L/2 )²

= 4 x mL² / 4

= m L² .

Answer:

"Emergency resource guidebook" would provide you with the best initial information about this chemical

Explanation:

This guidebook is for the first responders in case of the beginning of any dangerous goods or the hazardous materials transportation incident. It is used in firefighters, paramedics and for the police officers, in countries like Canada, Mexico and also in the United states when responding to these accident cases becomes delay. The book has different colours in it, for chemicals it will be green colour whereas the blue or the yellow colour shows the toxic inhalation materials. In TIH it has initial isolation distance and protective action distance information against the accident. The white is the host specific.
