<span>La segunda ley de Newton se conoce como la ley del movimiento de las partículas. <span>Dice que si sobre un cuerpo de masa en una sola fuerza Féliz que recibe una descarga de tal que F = ma.
</span></span>Y la primera <span>establece que un objeto permanecerá en reposo o con movimiento unifome rectilíneo al menos que sobre él actúe una fuerza externa.
Espero q te sirva :)</span>
Answer:
1402.73 m
Explanation:
Mass of Azurite=3.25 lb
Percent of copper in AZurite mineral=55.1%
Diameter of copper wire,d=0.0113 in
Radius of copper wire=
Density of copper=
1 lb=454 g
3.25 lb=
Mass of Azurite=
Mass of copper=
Density=
Using the formula
Volume of copper wire=
Radius of copper wire=
1 in=2.54 cm
Volume of copper wire=
Using the formula
1 m=100 cm
Hence, the length of copper wire required=1402.73 m
They both use small amouts of nuclar waves
Answer:
Please find the answer in the explanation.
Explanation:
Mention three disadvantages of friction between the parts of a machine
Three disadvantages of friction between the part of a machine are;
1. Friction causes wear and tear of machine parts.
2. Friction generates heat between the part of a machine.
3. Friction reduces the efficiency of a machine.
How does.
1 . oiling
2 using ball bearing
To reduce friction, you need to apply a lubricant. Oil and grease are examples of a lubricant. A lubricant helps to reduce friction by making the surface of the machine parts slippery thereby reducing tear and wear.
Also, friction can be reduced by using ball bearing which will allow the rolling of machine parts.
