In mammals, the weight of the heart is approximately 0.5% of the total body weight. Write a linear model that gives the heart we

Inertia is universally present. It's important to note that inertia doesn't serve as the force keeping objects in circular paths; that role belongs to centripetal force, which is not always present. Centripetal force actively pulls objects towards the center of a circle. Both inertia and centripetal force contribute to the phenomenon of circular motion. Thank you, and enjoy your day;)

Answer: c. 4.56 × 105 J

Explanation:

Given the mass of the lead brick, m = 7.25 kg

Starting temperature T1 = 18.0 °C

Ending temperature T2 = 328 °C

The specific heat capacity for lead, c = 128 J/(kg∙°C)

And the latent heat of fusion Lfusion = 23,200 J/kg

The required energy Q =?

Using the following equations

Energy required, Q = mc (T2 - T1) + mLfusion

Substituting in the values we have: 7.25 kg * 128 J/(kg∙°C) * (328 - 18°C) + 7.25 kg * 23200 J/kg

= 455880 J

= 4.56 x 10^5 J
