Answer:
Masa, m = 0.088 kg
Explanation:
Given the following data;
Temperatura inicial = 30°C
Temperatura final = 120°C
Capacidad calorífica específica = 138J/kg.K
Calor absorbido, Q = 4400 cal.
Para encontrar la masa;
La capacidad calorífica viene dada por la fórmula;
Dónde;
Q representa la capacidad calorífica o la cantidad de calor.
m representa la masa de un objeto.
c representa la capacidad calorífica específica del agua.
dt representa el cambio de temperatura.
dt = T2 - T1
dt = 120 - 30
dt = 90°C to kelvin = 273 + 90 = 363K
Sustituyendo en la fórmula, tenemos;
Masa, m = 0.088 kg
Answer:
17.5
or
1.1 g/min
I know it's one of these, try getting a second opinion
Answer:
x = ½ aw t²
x = d − ½ az t²
Explanation:
The position of each car at time t is:
x = x₀ + v₀ t + ½ at²
For car W:
x = 0 + (0) t + ½ aw t²
x = ½ aw t²
For car Z:
x = d + (0) t + ½ (-az) t²
x = d − ½ az t²
Solving the system of equations for x will give us the location the cars meet (relative to car W's starting point).
According to the theory, energy realized during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate). Cellular respiration is the process by which organism use oxygen to break down food molecule to get chemical energy for cell function
The environmental impact of mining affects, nesting habitats for wildlife. Wildlife either moves on, or dies.
hope this helps:)
