(For example, if you used a lunch meat that claimed to be 97% fat-free, were just 3% of its calories provided by fat?) If the ma

nufacturer made such claims, how do you explain the difference between the manufacturer's claims and your findings?

The difference between the manufacturer's claims and your findings is, the manufacturer is concerned about amount of fat in the meat while you are concerned about calories.

<h3>Difference between your findings and the manufacturers claim</h3>

Your findings concluded that only fat can provide calories needed in the body, perhaps other classes of food or nutrients in the meat can provide calories as well.

In the manufacturer's claim there are about 3% fat in the lunch meat and doesn't necessary mean that all the calories needed is the 3% fat.

Thus, there are lots of difference between your findings and the manufacturer's claim. The manufacturer is concerned about amount of fat in the lunch meat while you are concerned about calories in the meat.

Two resistors, R 1 = 2.01 Ω R1=2.01 Ω and R 2 = 5.29 Ω R2=5.29 Ω , are connected in series to a battery with an EMF of 24.0 24.0
Lesechka [4]

Answer:

I = 3.3 A

V2 = 17.4 V

Explanation:

a)

  • In a circuit series, the current is the same through any point of the circuit.
  • Assuming the resistors are in the linear zone of operation, we can apply Ohm's Law to both resistors, as follows:

        V = I* r_{eq} = V_{R1} + V_{R2} = (I*R_{1})  + (I*R_{2}) = I * (R_{1} + R_{2})\\  \\ R_{eq} = R_{1} + R_{2}

  • Therefore, we can find the current I as follows:

        I =\frac{V}{R_{eq} } = \frac{24.0 V}{7.3 \Omega} = 3.3 A

b)

  • Applying Ohm's law to R2, we can find the voltage through R2 as follows:

       V_{R2} = I* R_{2} = 3.3 A * 5.29 \Omega = 17.4 V

Before going in for an annual physical, a 70.0-{\rm kg} person whose body temperature is 37.0{\rm ^{\circ} C} consumes an entire
Grace [21]

Answer:

A) The person's body temperature T_final after equilibrium is attained = 36.85°C

B) The change in the person's temperature after equilibrium is attained = 0.15°C

A high-quality medical thermometer can measure temperature changes as small as 0.1°C, hence, YES, it would detect the minute drop by 0.15°C too.

Explanation:

If we assume that the soft drink has the same density as water (since it is stated in the question that it is mostly water).

Density of water = 1 g/mL = 1 kg/L

Ignoring any heating by the person's metabolism,

A) So, heat lost by the human body = heat gained by the soft drink as it attains thermal equilibrium with the human body

Let the final temperature of the human body + soft drink set up be T

Heat lost by the human body = mCΔT

m = mass of the human body = 70.0 kg

C = Specific heat capacity of the human body = 3480 J/kg.K

ΔT = Temperature change of the human body = 37 - (Final temperature) = 37 - T

Heat lost by the body = 70 × 3480 × (37 - T)

= (9,013,200 - 243,600T) J

Heat gained by soft drink = mCΔT

m = mass of the soft drink = density × volume = 1 × 0.355 = 0.355 kg

C = specific heat capacity of the soft drink = specific heat capacity of the soft drink = 4182 J/kg.K

ΔT = (final temperature) - 12 = (T - 12)

Heat gained by the soft drink = 0.355 × 4182 × (T - 12) = (1,484.61T - 17,815.32) J

heat lost by the human body = heat gained by the soft drink as it attains thermal equilibrium with the human body

(9,013,200 - 243,600T) = (1,484.61T - 17,815.32)

9,013,200 + 17,815.32 = 1,484.61T + 243,600T

9,031,015.32 = 245,084.61T

T = (9,031,015.32/245,084.61)

= 36.8485614825 = 36.85°C

B) The change in the person's temperature = 37 - 36.85 = 0.15°C

A high-quality medical thermometer can measure temperature changes as small as 0.1°C, hence it would detect the minute drop by 0.15°C too.

Hope this Helps!!!

A 0.075 kg ball in a kinetic sculpture is raised 1.33 m above the ground by a motorized vertical conveyor belt. A constant frict
irinina [24]

Answer : The total work done in raising the ball is, 0.98 J

Explanation : Given,

Mass of the ball = 0.075 kg

Height raised of the ball = 1.33 m

As we know that the object is moving with the constant velocity, that means the work done against the gravity will be the net-work done.

So, the work done will be:

w=mgh

where,

w = work done

m = mass of ball

h = height of ball

g = acceleration due of gravity = 9.8m/s^2

Now put all the given values in the above formula, we get:

w=(0.075kg)\times (9.8m/s^2)\times (1.33m)

w=0.97755J=0.98J

Thus, the total work done in raising the ball is, 0.98 J
