First, we must transform the pressure into SI units, considering that
:
The starting and ending volumes of the gas will be as follows (keeping in mind that
):
Thus, the work performed on the gas by its surroundings is
The positive outcome indicates that this work leads to a rise in the gas's internal energy.
Respuesta:
Se pueden recargar.
Poseen una vida útil mayor.
Son reutilizables.
Explicación:
Las baterías de plomo-ácido y las pilas Leclanché son tipos de células electroquímicas.
Las pilas Leclanché son células primarias. Estas células producen reacciones químicas que generan corriente eléctrica de manera irreversible.
Por su parte, las baterías de plomo-ácido son células secundarias que permiten la reversibilidad de la corriente eléctrica generada.
Esto hace que las baterías de plomo-ácido sean reutilizables, con mayor durabilidad y un tiempo de vida más prolongado.
Answer:
57.94°
Explanation:
We understand that the formula for flux is
where Ф represents flux
E indicates electric field
S denotes surface area
θ signifies the angle between the electric field direction and the surface normal.
It is given that Ф= 78 
E=
S=
= 
=0.5306
θ=57.94°
Objects in vertical motion are an illustration of non-uniform motion. At the peak of the circle, centripetal force is balanced by the object's weight. Therefore, the minimum speed required at this top point is given by v =
=
= 5.23 m/s. As the sphere descends from the top to the bottom of the circle, according to the law of conservation of energy, potential energy can be expressed as
, where h signifies the diameter of the circle (2r). Hence, the expression will be written as
where u is the velocity at the lowest point. Consequently, the modified equation is
= 
= 
= 11.71 m/s. The collision of the dart with the bullet is an inelastic one. According to the conservation of momentum: v = 
= 
= 
= 58.55 m/s. Thus, the dart's minimum initial speed for the combined system to complete a circular loop post-collision is 58.55 m/s.
