Answer:
V2 = 4.5 dm³
Explanation:
Dados los siguientes datos;
Volumen inicial = 3 dm³
Temperatura inicial = 20°C Temperatura final = 30°C
Para encontrar el nuevo volumen V2, usaríamos la ley de Charles.
Charles afirma que cuando la presión de un gas ideal se mantiene constante, el volumen del gas es directamente proporcional a la temperatura absoluta del gas.
Matemáticamente, Charles está dado por;
Dónde;
V1 y V2 representan los volúmenes inicial y final respectivamente.
T1 y T2 representan las temperaturas inicial y final, respectivamente.
Haciendo V2 como la fórmula del sujeto, tenemos;
V2 = 4.5 dm³
9.8 m/s is the acceleration due to gravity
We know that centripetal acceleration is nothing but the ratio of the square of the tangential velocity to that of the radius vector.
a=v*v/r=ωωrr/r
=ωωr
=2πf2πfr
=2π2πr/TT
=97m/secsec
Answer:
(7.8) x (9.8 m/s) = 76.44 m/s
during the time he spent falling.
Since his falling speed was zero when he 'stepped' off of the top,
he hit the ground at 76.44 m/s.
That's about 170 miles per hour.
I'll bet he left one serious crater!
I hope this helps too! :D
