Which instrument changes kinetic energy into electrical energy?

Physics
1 answer:
Schach [20]3 years ago

Answer:

dynamo

Explanation:

As we all know, dynamos are used in bicycles. When we cycle, the tire rotates, which means kinetic energy. And when the wheel rotates, the dynamo wheel starts to rotate. With that, the motor inside the dynamo starts to rotate. Then it generates electricity, which means electrical energy.

A solenoid 91.0 cm long has a radius of 1.50 cm and a winding of 1300 turns; it carries a current of 3.60 A. Calculate the magni
irinina [24]

The magnitude of the magnetic field inside the solenoid is 6.46 \times 10^{-3} \ T.

The given parameters;

  • <em>length of the solenoid, L = 91 cm = 0.91 m</em>
  • <em>radius of the solenoid, r = 1.5 cm = 0.015 m</em>
  • <em>number of turns of the solenoid, N = 1300 </em>
  • <em>current in the solenoid, I = 3.6 A</em>

The magnitude of the magnetic field inside the solenoid is calculated as;

B = \mu_0 nI\\\\B = \mu_o(\frac{ N}{L} )I\\\\

where;

\mu_o is the permeability of frees space = 4π x 10⁻⁷ T.m/A

B = (4\pi \times 10^{-7}) \times (\frac{1300}{0.91} ) \times 3.6\\\\B = 6.46 \times 10^{-3} \ T

Thus, the magnitude of the magnetic field inside the solenoid is 6.46 \times 10^{-3} \ T.

The instruments attached to a weather balloon have a mass of 5 kg. The balloon is released and exerts an upward force of 106 N o
Illusion [34]

Answer:

acceleration of the balloon is 11.4 m/s²

and

The instruments accelerate downwards at 9.8 m/s²

Explanation:

given data

mass = 5 kg

force = 106 N

acceleration of gravity = 9.8 m/s²

to find out

the acceleration of the balloon and the instruments

solution

we find weight of the instruments that is

weight W = mg

here m is mass and g is acceleration of gravity

W = 5 ×9.8

weight W = 49 N

and

so net upward force on the instruments is

net upward force F = 106 - 49

net upward force F = 57 N

and

The acceleration of the balloon is

Force = ma

57 = 5 a

a = 11.4 m/s²

acceleration of the balloon is 11.4 m/s²

and

The instruments accelerate downwards at 9.8 m/s²
