Answer:
Explanation:
La aceleración es directamente proporcional a la magnitud de la fuerza resultante. Así, si se duplica la fuerza, la aceleración se duplica; si se triplica la fuerza, se triplica la aceleración. Por otro lado, la aceleración es inversamente proporcional a la masa del cuerpo que se acelera.
Answer:
efficiency of a simple machine is defined as the ratio of useful work done by a machine (output work) to the total work put into the machine (input work). For ideal or perfect machine, work output is equal to the work input.

Answer:
Jupiter has an internal heat source.
Explanation:
It is believed that most of this heat is the residual (left over) heat from the time when formation of early Solar nebula took place. Jupiter absorbs energy from the Sun in the form of light and the coverts it into heat and later releases this heat in the form of thermal radiation.
It is recorded that Jupiter emits almost twice amount of energy from the amount which it receives from the sun. It is this internal source of energy and sunlight which provide energy to Jupiter's atmosphere.
However, this phenomenon of internal heat source is also seen in other celestial bodies as well such as Saturn, Neptune, Stars, etc.

This is the definition for brass:
“Brass is an alloy of copper and zinc, in proportions which can be varied to achieve varying mechanical and electrical properties. It is a substitutional alloy: atoms of the two constituents may replace each other within the same crystal structure.” Here is an image comparing it to gold
