What properties does electrical resistance in a wire depend on?
Anvisha [2.4K]

Answer:

Explanation:

You can always  figure out something to say about a question like this if you have a formula to work with. Likely you do.

There are many ways it can be written

R = k * L / A

So here's the answer.

Resistance = k  which depends of the properties of the material used to make the wire * the  Length of the wire  divided by the cross sectional area of the wire.

The magnetic field at the center of a 1.0-cm-diameter loop is 2.5 mT.
olga nikolaevna [1]

Answer:

(a) The current in the wire is 19.89 A

(b) The distance from the wire is 0.159 cm

Explanation:

Given;

magnetic field, B = 2.5 mT

diameter of the wire, d = 1 cm

radius of the wire, r = 0.5 cm = 0.005 m

(a) The current in the wire is calculated as;

I = \frac{2Br}{\mu_0} \\\\I = \frac{2\times 2.5 \times 10^{-3} \times 0.005 }{4\pi \times 10^{-7} } \\\\I = 19.89 \ A

(b) The distance from the wire where the magnetic field is 2.5 mT is calculated as;

B = \frac{\mu_0 I}{2\pi d} \\\\where;\\\\d \ is \ the \ distance \ from \ the \  wire\\\\d = \frac{\mu_0 I}{2\pi B} = \frac{4 \pi \times 10^{-7} \times 19.89}{2\pi \times 2.5 \times 10^{-3}}  = 0.00159 \ m = 0.159 \ cm

2. Grandma accelerates on her skateboard at 8 m/s/s. Her mass is 95 kg. What force does she exert to do this?
aleksandrvk [35]

Answer:

<h2>760 N</h2>

Explanation:

The force acting on an object given it's mass and acceleration can be found by using the formula

force = mass × acceleration

From the question we have

force = 95 × 8

We have the final answer as

<h3>760 N</h3>

Hope this helps you

Como determino la densiad de un objeto?
sveta [45]

Answer:

La densidad (más precisamente, la densidad de masa volumétrica; también conocida como masa específica), de una sustancia es su masa por unidad de volumen. El símbolo más utilizado para la densidad es la letra griega en minúsculas rho), aunque también se puede utilizar la letra latina D. Matemáticamente, la densidad se define como masa dividida por volumen: .m/V donde es la densidad, m es la masa y V es el volumen. En algunos casos (por ejemplo, en la industria del petróleo y el gas de los Estados Unidos), la densidad se define libremente como su peso por volumen unitario, aunque esto es científicamente inexacto – esta cantidad se llama más específicamente peso específico.
