Answer:

Characteristics are displayed by hard magnetic materials:

B. relatively large hysteresis loop.

D. Magnetization and demagnetization require relatively high applied fields.

<u>Explanation</u>:

They are otherwise called as the permanent magnets, they have the ability to retain is quality even after being magnetised. They have the ability of greater hysteresis loop, it is the relation between the induced magnetic flux to that of magnetizing force. When it is high gives the hard magnetic material.  They have high retentivity and coercivity. This means the driving field during magnetization is null. To get coercivity the driving field should be made in the opposite direction.

A passenger train travels 392 mi in the same time that it takes a freight train to travel 322 mi. If the passenger train travels
Yuri [45]

Answer:

Explanation:

Given

distance traveled by  Passenger train is d_1=392\ mi

distance traveled by  Freight train is d_2=322\ mi

Both take same time to travel

suppose speed of freight train is x mph

so speed of passenger train is 20+x mph

we know time=\frac{distance}{speed}

t=\frac{392}{20+x}=\frac{322}{x}

392x=322x+322\times 20

70x=322\times 20

x=92\ mph

speed of passenger train x+20=112\ mph
