Copper has a specific heat capacity of 3.80 x 102 Jkg-1K-1 What temperature

Physics

Answer:

4.91 K

Explanation:

From the question,

q = cm(Δt)................ Equation 1

Where q = heat, c = specific heat capacity of copper, m = mass of copper, Δt = temperature change.

make Δt the subject of the equation

Δt = q/cm.................. Equation 2

Given: q = 560 J, m = 300 g = 0.3 kg, c = 380 J/kg.K

Substitute these values into equation 2

Δt = 560(0.3×380)

Δt = 560/114

Δt = 4.91 K

ElenaW [278]

Answer:

The answer to your question is a = 1.3 m/s²

Explanation:

Centripetal acceleration is the motion of a body that transverse a circular path.

Data

mass = 7 kg

radius = r = 1.3 m

angular rate = w = 1.0 rev/s

centripetal acceleration = a = ?

Formula

a = rw²

Substitution

a = (1.3)(1)²

Simplification and result

a = 1.3 m/s²
