Group of answer choices
A. ruler, balance
B. beaker, crucible
C. flask, Bunsen burner
D. graduated cylinder, balance
Answer:
D. graduated cylinder, balance
Explanation:
In this scenario, A student has been assigned to measure the density of an irregularly shaped piece of metal.
The apparatus which would be most appropriate to carry out this task is a graduated cylinder and balance.
A graduated cylinder can be defined as a measuring cylinder used for the measurement of the volume of an irregularly shaped piece of metal or liquids. It is typically marked with horizontal lines on its side as units of measurement for volume. The balance is then used to weigh the metals mass.
Answer:
1. 
2. 
Explanation:
1. La altura máxima se puede calcular usando la siguiente ecuación:
(1)
Where:
: es la velocidad final = 0 (en la altura máxima)
: es la velocidad inicial horizontal en "y"
g: es la gravedad = 9.81 m/s²
h: es la altura máxima =?
La velocidad incial en "y" se puede calcular de la siguiente manera:
Resolviendo la ecuación (1) para "h" tenemos:
2. Para calcular el alcance horizontal podemos usar la ecuación:
Primero debemos encontrar el tiempo cuando la altura es máxima ( = 0).
Ahora, como el tiempo de subida es el mismo que el tiempo de bajada, el tiempo máximo es:
Finalmente, el alcance horizontal es:
