Increasing the amount of current that flows through a wire ______ the strength of an electromagnet

Anestetic [448]

Electromagnet is in form of solenoid

and the magnetic field due to solenoid is given as

$B = \mu_0 n i$

here

i = current in the loop

so when we increase the current in electromagnet the magnetic field of the solenoid will increase

this will increase the strength of the electromagnet

so the answer would be

<em>INCREASE</em>

A clown at a birthday party has brought along a helium cylinder, with which he intends to fill balloons. When full, each balloon

Furkat [3]

Answer:

Explanation:

According to Boyle's law:

$P\times V=constant$

Thus,

$P_{cylinder}\times V_{cylinder}=n\times P_{balloon}\times V_{balloon}$

Where, n is the number of the balloons

From the question, it is given that:

For balloon:

P = $1.2\times 10^5$ Pa

V = 0.040 m³

For cylinder:

P = $1.80\times 10^7$ Pa

V = 0.0031 m³

So,

$1.80\times 10^7\times 0.0031=n\times 1.2\times 10^5\times 0.040$

n = 11.625

<u>So, Maximum number of balloons = 11</u>
