Answer:
No, because g=9.8m/s^2 regardless of mass
Explanation:
As we know that the rock is suspended at a given height above the surface
so here the gravitational potential energy of the rock will convert into its kinetic energy
so here we will have
so the final speed does not depends on the mass of the object but the only thing that it depends is the height.
so here correct answer is given as
No, because g=9.8m/s^2 regardless of mass
Answer:
How are physical and chemical changes similar and different? (compare and contrast) (Physical and chemical changes are similar because matter experiences a change in state, Physical changes are different because matter remains the same substance, just in a different state, whereas chemical changes change the matter
Answer:
Thermocline.
Explanation:
The sunlight does not reaches deep inside the water called as the deep layer in which the temperature of water is low and it is cold. These two layers are separated by the middle layer called as the thermocline, which is warm at the top and cold at the bottom.
Explicación:
a) Según la segunda ley de movimiento de Newton;
Fuerza = Masa * aceleración
Dado
Masa del coche = 200 kg
Fuerza aplicada = 800N
aceleración = Fuerza / Masa
aceleración = 800/200
aceleración = 4m / s²
b) Para que obtengamos la velocidad final del automóvil, necesitaremos el tiempo.
Suponiendo que el tiempo necesario es de 2 segundos
Sabemos que aceleración = velocidad / tiempo
velocidad = aceleración * tiempo
velocidad = 4 * 2
velocidad = 8 m / s
Por lo tanto, la velocidad final será de 8 m / s si el tiempo es de 2 s.
