Responder: A.) 24.5m / s B.) 30.625m C.) 89.375m
Explicación:
Dado lo siguiente:
Altura desde la cual se cae el cuerpo = 120 m
Tiempo (t) = 2.5s
A.) La velocidad que toma:
El cuerpo cayó desde una altura;
velocidad inicial (u) = 0
Para calcular v:
V = u + en
Donde a = aceleración debido a la gravedad = 9.8m / s
v = 0 + (9.8) (2.5)
v = 24.5 m / s
B) Cuánto ha disminuido.
Usando la ecuación de movimiento:
S = ut + 0.5at ^ 2
Donde S = distancia
S = 0 × 2.5 + 0.5 (9.8) (2.5 ^ 2)
S = 0 + 0.5 (9.8) (6.25)
S = 30.625 m
Esta es la distancia recorrida después de 2.5 segundos Altura o distancia ha disminuido en 30.625 m
C.) ¿CUÁNTO FALTA? Por lo tanto, 120m - 30.625m = 89.375m
Answer:
v = 7671.57 m/s
T = 1.55 hours
Explanation:
mass of Earth, M = 6 x 10^24 kg
Radius of earth, R = 6400 km = 6.4 x 10^6 m
height, h = 400 km
Velocity is given by
where, G be the universal gravitational constant.
G = 6.657 x 10^-11 Nm^2/kg^2
v = 7671.57 m/s
Let T b the period
T = 5566.53 second
T = 1.55 hours
Answer:
The Jovian planets formed beyond the Frostline while the terrestrial planets formed in the Frostline in the solar nebular
Explanation:
The Jovian planets are the large planets namely Saturn, Jupiter, Uranus, and Neptune. The terrestrial planets include the Earth, Mercury, Mars, and Venus. According to the nebular theory of solar system formation, the terrestrial planets were formed from silicates and metals. They also had high boiling points which made it possible for them to be located very close to the sun.
The Jovian planets formed beyond the Frostline. This is an area that can support the planets that were made up of icy elements. The large size of the Jovian planets is as a result of the fact that the icy elements were more in number than the metal components of the terrestrial planets.
Answer:
3/360 is 120. your velocity is 120

<h2>
Hello!</h2>
The answer is A. Chemical energy to heat energy to kinetic energy to electrical energy.
<h2>
Why?</h2>
Let's check the energy conversion given in the statement:
Chemical energy: Chemical energy is usually obtained from a natural resource combustion. For this particular case is the result of natural gas combustion.
Heat energy: Heat energy comes from chemical reactions such as natural gas combustions.
Kinetic energy: Kinetic energy is obtained by turbines transforming the pressurized steam on mechanical movement. Turbines are formed by a turbine that absorbs the heat energy to do mechanical work and transmit it to an output rotating shaft.
Electrical energy: Electrical energy is generated by gas turbines when the rotating output shaft is connected to an electrical generator. Electrical generators use mechanical energy to generate electrical energy by using electromagnetic induction. Electrical generators are basically formed by a rotor and a stator.
Have a nice day!
