faltersainse [42]

Answer:

324

Step-by-step explanation:

The shirt would be the same value because they are the same so

288÷3=96

Pi Shirt = 96

then work out the 3rd one to find out the balloons

98+ balloon + balloon= 226-96=130÷2= 65

Balloons = 65

then work out the 2nd one 195÷65=3

Pizza = 3

Then 4th one

25+1=26-3=29

Maccoroni = 29

Last question

96×3+65-29=324

PLS HELP ME ASAP!!!!!!!!! ill give thanks, and five stars
docker41 [41]

Answer:

A

Step-by-step explanation:

The additive inverse property states that if we have a number a, then:

a+(-a)=0

Here, we have the equation:

2x=542

And we divide both sides by 2:

2x/2=542/2

To acquire:

x=271

So, we did <em>not</em> use the additive inverse property since we didn't add anything.

Instead, we used the<em> division property of equality</em> by dividing both sides by 2.

So, our answer is A.

And we're done!

A hollow metal sphere has 6 cm inner and 8cm outer radii. The surface charge densities on the exterior surface is +100 nC/m2 and
natulia [17]

Answer:

<h2>Outer Electric Field is 11250 N/C.</h2><h2>Inner Electric Field is -10000 N/C.</h2>

Step-by-step explanation:

First of all, we need to read carefully and analyse the problem. As you can see, is an electrical subject, and it's given surface charge densities and radius.

So, to calculate electric fields, we need to find the proper equation to do so: E=k\frac{q}{r^{2} }; as you can see, first we need to find the charges.

We can find all charges using the surface charge densities, because it has the next relation: p=\frac{q}{A}; which indicates that charge density is the amount of charge per area. But, there's a problem, we don't have areas, so we have to calculate them first with this relation: S=4\pi r^{2}; which gives us the surface of a sphere.

The inner surface: Si=4\pi (0.06m)^{2} = 0.04 m^{2}

The outer surface: S=4\pi (0.08m)^{2}=0.08m^{2}

Now we can calculate the charges,

Inner charge: Qi=pA=(-100\frac{nC}{m^{2} } )(0.04m^{2} )=-4nC

Outer charge: Qo=pA=100\frac{nC}{m^{2} } )(0.08m^{2} )=8nC

Then, we are able to calculate both fields:

Inner field: Ei=k\frac{Qi}{r^{2} }=9x10^{9} \frac{Nm^{2} }{C^{2} }\frac{-4x10^{-9} }{0.06m^{2} }=-10000\frac{N}{C}

Outer field:  Eo=k\frac{Qo}{r^{2} }=9x10^{9} \frac{Nm^{2} }{C^{2} }\frac{8x10^{-9} }{0.08m^{2} }=11250\frac{N}{C}

The directions that field have is opposite each other, the inner one has an inside direction, and the outer electric field has an outside direction.
