Answer:
The mass of the rock is
Explanation:
From the question we are told that
The length of the string is
The angular velocity is
The tension on the string is
Generally the centripetal force acting on the rock is mathematically evaluated as
making m the subject of the formula
substituting values
The second choice is the answer
A beta particle is identical to : an electron
Both of beta particle and electron are high in energy and move in high speed.

Answer:3N
Explanation:
SUBTRACT THE FRICTIONAL FORCE FROM THE ACTING FORCE
4-1=3
Responder:
20.3 ° C
Explicación:
<u>Según la ley de Charles</u>: <em>cuando la presión sobre una muestra de gas seco se mantiene constante, la temperatura y el volumen estarán en proporción directa.
</em>
Paso uno:
datos dados
Temperatura T1 = 20 ° C
Temperatura T2 =?
Volumen V1 = 12.2 cm ^ 3
Volumen V2 = 12.4 cm ^ 3
Aplicar la relación temperatura y volumen
sustituyendo tenemos
Cruz multiplicar tenemos
Temperatura delle braci 20.3°C
