A solenoid has a magnetic field of magnitude 0.50T when carrying a current of 400 A. The solenoid is 8.0 m long. What is the num

mixer [17]

Answer:

The correct answer is "995.22 turns".

Step-by-step explanation:

The given values are:

Magnetic field,

B = 0.50 T

Current,

i = 400 A

Length of solenoid,

L = 8.0 m

As we know,

⇒ $B=\mu_0ni$

then,

⇒ $n=\frac{B}{\mu_0i}$

On substituting the given values, we get

⇒ $=\frac{0.50}{4 \pi\times 10^{-7}\times 400}$

⇒ $=\frac{0.50}{5.024\times 10^{-4}}$

⇒ $=995.22 \ turns$

The sum of 3 and a number is between -2 and 17.

kumpel [21]

Answer:

The number, x = { -5 < x < 14}

This means x is any integer between -5 and 14

Step-by-step explanation:

From the statement, let the number be x

3 + x = y; y = { -2 < y < 17}

This means that y is any integer between -2 and 17

Therefore, x = y - 3

Subtract 3 from the limits of y

i.e. -2 - 3 = -5 and 17 - 3 = 14

Hence, x = { -5 < x < 14}
