C) During chemical reaction, total mass remains the same.
This is because due to the law of conservation of mass, stating that in a chemical reaction, neither mass will be created nor destroyed. So, the total mass will not change when chemical reactions occur.
Answer:
Total energy = 1000J
KE = 500J
PE = 500J
Explanation:
As you may know, the equation for gravitational potential energy is mgh (weight x height)
If the skateboard is halfway down, that means it is at half the height. As the skateboard speeds up (as it goes downward), the potential energy becomes kinetic energy. Since it has 500J of kinetic energy at half way down, it means it had double that amount of Potential energy at the top (1000J). Since half of that became kinetic energy, there is only 500J of PE left.
Total energy = KE + PE = 1000J
KE = 500J
PE = 500J
Answer:
Explanation:
F = m * a
The apple's acceleration is not influenced by the acceleration due to gravity for this question. In real life it most certainly is influenced by gravity.
F = m * a
F = 10 Newtons.
a = 6 m/s^2
m = 10/6 = 1.66 kg. Mighty large apple
Answer:
En el deporte, la persona que lo práctica tiene que adecuarse a él, por el contrario cuando hablamos de actividad física el objetivo pasa por programar, dosificar y adecuar en entrenamiento a las características, necesidades y objetivos de cada persona.
