Um bloco de peso igual a 10 N, preso a uma mola de constante elástica 50 N/m e inicialmente indeformada, é solto (sem velocidade
3241004551 [841]

Answer:

energia cinética

Explanation:

Passo um:

Dados fornecidos

Um bloco de peso igual a 10 N,

Constante de mola k = 50N / m

Passo dois:

A forma de energia formada é a energia cinética

Passo dois:

Da lei de Hooke, F = ke

e = F / k

e = 10/50

e = 0,2m

podemos resolver a energia cinética aplicando a fórmula

KE = 1 / 2ke ^ 2

KE = 0,5 * 50 * (0,2) ^ 2

KE = 0,5 * 50 * 0,04

KE = 1J

A gas is contained in a vertical, frictionless piston–cylinder device. The piston has a mass of 3.2 kg and a cross-sectional are
Lapatulllka [165]

Answer:

146.826 KPa

Explanation:

Given:

The mass of the piston = 3.2 kg

Cross-sectional area = 35 cm²

Force exerted by the spring = 110 N

Atmospheric pressure = 95 KPa

Now,

the total pressure inside the cylinder is the sum of all the pressure exerted on it i,e the pressure due the weight of the piston, pressure due to the force by the spring and the atmospheric pressure.

Now,

the pressure due to the weight of the piston = Weight / Area

= 3.2× 9.81 / 0.0035

= 31.392 / 0.0035

= 8969 Pa

= 8.969 KPa

And,

The pressure by the spring = 150 N / 0.0035

or

The pressure by the spring = 42,857 Pa = 42.857 KPa

Thus,

The total pressure

95 + 8.969 + 42.857 = 146.826 KPa

The most distant stars we can currently measure stellar parallax for are approximately Group of answer choices 10,000 parsecs aw
vlada-n [284]

The most distant stars we can currently measure stellar parallax for are approximately 1,000 parsecs away.

<h3>What is a parsec?</h3>

A parsec is a unity used to measure distance in the Universe, which is hard to understand with human thinking.

A parsec equals to approximately 3.20 light-years, which is  a small distance in the Universe.

In conclusion, the most distant stars we can currently measure stellar parallax for are approximately 1,000 parsecs away.
