~ A thermometer is an instrument that measures temperature. It can measure the temperature of a solid such as food, a liquid such as water, or a gas such as air. The three most common units of measurement for temperature are Celsius, Fahrenheit, and kelvin. The Celsius scale is part of the metric system.

Por un solenoide de 6500 espiras y 25 cm de longitud circula una corriente de 0,6 amperios. ¿Cuál es el valor del campo magnétic

9966 [12]

Answer:

Magnetic field, B = 0.0196 T

Explanation:

A current of 0.6 amps flows through a solenoid 6500 turns and 25 cm long. What is the value of the magnetic field inside it?

We have,

Current, I = 0.6 A

Number of turns in the solenoid, N = 6500

Length of solenoid, l = 25 cm = 0.25 m

The magnetic field inside the solenoid is given by :

$B=\mu_o\dfrac{N}{l}I\\\\B=\dfrac{4\pi \times 10^{-7}\times 6500\times 0.6}{0.25}\\\\B=0.0196\ T$

So, the value of the magnetic field inside the solenoid is 0.0196 T.

taurus [48]

Answer:

I = 0.483 kgm^2

Explanation:

To know what is the moment of inertia I of the boxer's forearm you use the following formula:

$\tau=I\alpha$ (1)

τ: torque exerted by the forearm

I: moment of inertia

α: angular acceleration = 125 rad/s^2

You calculate the torque by using the information about the force (1.95*10^3 N) and the lever arm (3.1 cm = 0.031m)

$\tau=Fr=(1.95*10^3N)(0.031m)=60.45J$

Next, you replace this value of τ in the equation (1) and solve for I:

$I=\frac{\tau}{\alpha}=\frac{60.45Kgm^2/s ^2}{125rad/s^2}=0.483 kgm^2$

hence, the moment of inertia of the forearm is 0.483 kgm^2
