Formula:
F = ma
m = F÷A
m: mass F:force A: accelerarion
m = 450N ÷ 15m/s^2
= 30kg
Hope this helps :)
Answer:
a) falso
b) verdadero
c) falso
d) falso
e) verdadero
Explanation:
A) FALSO: la distancia recorrida es independiente del punto de partida y del punto de llegada
B) VERDADERO: para que el ciclista recorra la pista de ida y vuelta es necesario que su velocidad cambie, por lo tanto la aceleración es diferente de cero.
C) FALSO
D) FALSO: en todo momento hay una distancia recorrida en un tiempo en específico, es decir, una rapidez.
E) VERDADERO: el despazamiento sí depende de la distancia entre el punto de llegada y el punto de salida.
According to the third rule of series circuit, the total voltage is equal to the sum of individual voltages. These proves that the statement above "<span>When voltage sources are connected in series, the total voltage is equal to the algebraic sum of the individual voltages?" is TRUE.</span>
A mechanical advantage less than ' 1 ' means the output <u>force</u> is less than the input
force. But <em>distance</em> is gained ... the load moves farther than the driving force moves.
An example of all this is a big father and his little 4-year-old daughter playing
on the see-saw in the park. He adjusts the board so that he's much closer
to the pivot than she is, and that way, their weights can balance each other.
It's set up so that the mechanical advantage from him to her is less than ' 1 '.
Now, look at what happens when Dad sits down on his end of the see-saw,
and pushes it down with his 180 pounds of force. At the other end, the board
is barely lifting her with a force of just 30 pounds. BUT ... as he sinks down
only 1 foot against his end of the board, <em>her</em> end rises 6 feet off the ground.
