Answer:

Calor absorbido, Q = 5023.2 Joules

Explanation:

Dados los siguientes datos;

Masa = 100g to kg = 100/1000 = 0.1kg

Temperatura inicial, T1 = 293.15 K

Temperatura final, T2 = 305.15K

Capacidad calorífica específica = 4186 j/kg.K.

Para encontrar la cantidad de calor necesaria;

La capacidad calorífica viene dada por la fórmula;

Q = mct

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 = 305.15 - 293.15

dt = 12 K

Sustituyendo en la fórmula, tenemos;

Q = 0.1*4186*12

Q = 5023.2

Calor absorbido, Q = 5023.2 Joules

Calculate the east component of a resultant 32.5 m/s, 35.0° east of north.
ValentinkaMS [17]

Answer:

East component is: 18.64 m/s

Explanation:

If the resultant is 32.5 m/s directed 35 degrees east of north, then we use the sin(35) projection to find the east component of the velocity:

East component = 32.5 m/s * sin(35) = 18.64 m/s

What is not an example of Absorption? (Physics)
amm1812

When a light wave strikes an object, it can be absorbed, reflected, or refracted by the object. All objects have a degree of reflection and absorption. ... In the natural world, light can also be transmitted by an object. That is, light can pass through an object with no effect (an x-ray, for example).
