Answer:

C. Metabolism

Explanation:

Although it is a process that we cannot visualize, we feel it daily in our day by day life. A clear example is when we consume food of any kind, each of these foods contains a reference amount of energy in kilocalories (kcal). These foods supply energy to the human body, this energy from food is used for different day actions, and much to maintain body temperature. When the human body is exposed to very low outside temperatures, the body is exposed to a considerable loss of energy in the form of heat transfer, so the person will begin to feel hungry so that the body needs calories from food to maintain body temperature at stable levels. Metabolism is essential in the human body, at the moment when the human being dies his temperature decreases because the metabolism stops working.

A concrete slab of mass 400 kg accelerates down a concrete slope inclined at 35°. The kinetic between the slab and slope is 0.60
belka [17]

I got you

Explanation:

normal force = 400 g cos 35

friction force up slope = .6 (400 g) cos 35

weight component down slope = 400 g sin 35

400 a = 400 g sin 35 - .6 (400 g cos 35)

a = g (sin 35 - .6 cos 35) = .082 g

I hope this helps you

You have 4.9 g of an unknown substance. To identify the substance, you decide to measure its specific heat and find that it requ
kifflom [539]

The unknown substance can be lithium, which has a specific heat capacity of approximately 3.5 J/gK.

Explanation:

When heat energy is supplied to a certain substance, the temperature of the substance increases according to the equation:

Q=mC_s \Delta T

where

Q is the amount of energy supplied

m is the mass of the sample

C_s is the specific heat capacity of the substance

\Delta T is the change in temperature

In this problem, we have

m = 4.9 g is the mass

Q = 668.85 J is the specific heat capacity

\Delta T = 39 K is the change in temperature

Solving for C_s, we find the specific heat capacity of the substance:

C_s = \frac{Q}{m\Delta T}=\frac{668.85}{(4.9)(39)}=3.5 J/gK

Looking at tables of specific heat capacity, we can see that the unknown substance can be lithium, which has a specific heat capacity of approximately 3.5 J/gK.
