Answer:
Período del tambor: , fuerza sobre la prenda:
, velocidad lineal del tambor:
, velocidad angular del tambor:
.
Explanation:
La expresión tiene un error por omisión, su forma correcta queda descrita a continuación:
<em>"Una prenda de 320 gramos de ropa gira en el interior de una lavadora si dicha lavadora tiene un radio de 40 centímetros y gira con una frecuencia de 4 hertz. Halle </em><em>a)</em><em> el período, </em><em>b) </em><em>la velocidad angular, </em><em>c) </em><em>la fuerza con la que gira la prenda y </em><em>d) </em><em>la velocidad lineal de la lavadora."</em>
El tambor gira a velocidad angular constante (), en radianes por segundo, lo cual significa que la prenda experimenta una aceleración centrífuga (
), en metros por segundo al cuadrado. En primer lugar, calculamos el período de rotación del tambor (
), en segundos:
(1)
Donde es la frecuencia, en hertz.
()
Ahora determinamos la fuerza aplicada sobre la prenda (), en newtons:
(2)
(2b)
Donde:
- Masa de la prenda, en kilogramos.
- Radio interior del tambor, en metros.
(,
,
)
La velocidad lineal de la lavadora es:
(3)
(,
)
Y la velocidad angular del tambor de la lavadora:
()
The initial velocity is 0.65 m/s
Explanation:
The motion of the roller coaster is a uniformly accelerated motion, so we can solve the problem by using the following suvat equation:
where
s is the displacement
u is the initial velocity
v is the final velocity
t is the time
For the roller coaster in this problem:
v = 35 m/s
t = 2.3 s
s = 41 m
Solving the equation for u, we find the initial velocity:

Answer: The chemical formula for the compound of these two elements is
Explanation:
For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
Here metal lead is having an oxidation state of +4 called as cation and sulphur non metal has oxidation state of -2 called as
. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral
