It requires 0.30 kJ of work to fully drive a stake into the ground. If the average resistive force on the stake by the ground is
LenaWriter [7]

Answer:

Length of the stake will be 0.3623 m

Explanation:

We have given energy required to fully drive a stake into ground = 0.30 KJ = 300 J

Average resistive force acting on the floor is equal to F = 828 N

We have to find the length of the stake

We know that work done is given by

W = Fd, here W is work done , F is average force and d is the length of the stake

So 300 = 828×d

d = 0.3623 m

So length of the stake will be 0.3623 m

¿Porque las medidas arbitrarias no se pueden estandarizar y usar en todos los paises?
Oksi-84 [34.3K]

Answer:

<em>Explicación completa más abajo</em>

Explanation:

<u>Estándares de Medición </u>

En física, química y otras ciencias exactas usamos magnitudes como el metro, segundo, kilogramo, etc. que son aceptadas internacionalmente y cualquier persona puede dar sus mediciones referidas a esos patrones estandarizados.

Si en algún lugar, alguien decide usar una unidad de medida no estándard, como por ejempl, la distancia entre su dedo meñique y pulgar y le pone un nombre (en mi país lo llamamos 'cuarta'), resulta que esa unidad no es única, pues depende del tamaño de la mano del que mide y de la forma como la estira. Aún asi, la precisión sería muy mala.

Es por eso que debemos ajustarnos a usar los patrones internacionales como el SI para expresar las magnitudes de los fenómenos que estudiamos
