sveticcg [70]

Given

v = 343 m/s

ac = 5g

ac = 5*9.8 m/s^2

ac = 49 m/s^2

where,

v: velocity

ac = centripetal aceleration

Procedure

We call the acceleration of an object moving in uniform circular motion—resulting from a net external force—the centripetal acceleration ac; centripetal means “toward the center” or “center seeking”.

Formula

\begin{gathered} a_c=\frac{v^2}{r} \\ r=\frac{v^2}{a_c} \\ r=\frac{(343m/s)^2}{49m/s^2} \\ r=2401\text{ m} \end{gathered}

The minimum radius not to exceed the centripetal acceleration is 2401 m.

Resting energy expenditure is a. slightly higher than basal energy expenditure. b. the same as basal energy expenditure. c. slig
kvv77 [185]

Answer:

B. Resting energy expenditure is the same with basal energy expenditure.

Explanation:

Basal Energy Expenditure can be explained as the energy required to execute essential metabolic functions e.g. coordination of enzymatic reactions in the body system.

On the other hand, Resting Energy Expenditure can be simply explained as the amount of energy expended or burnt when the body is resting.

Hence, in the context of definitions, and relating both definitions, it can be argued that Basal energy expenditure is simply the energy needed to execute essential metabolic functions e.g. coordination of enzymatic reactions in the body, with special emphassy on the body being at rest. Thus, in this context, Basal energy can be looked at through the prism of Resting energy expenditure. Consequently, this two definitions can be used interchangeably, with a special emphassy on perspective.

A heat engine operates between a hot reservoir with a temperature of 400 K and a cold reservoir with a temperature of 300 K. The
natali 33 [55]

Answer:

Explanation:

Given

Temperature of Hot reservoir T_1=400 K

Temperature of Cold reservoir T_2=300 K

Heat reservoir Q=500 J

Work done W=150 J

heat Exhaust Q_{rejection }=350 J

Q=W+Q_{rejected}

500=150+350

L.H.S=R.H.S

thus it follows first law

\eta _{carnot}=1-\frac{T_L}{T_H}

\eta _{carnot}=1-\frac{300}{400}

\eta _{carnot}=0.25

Cycle Efficiency

\eta =\frac{W}{Q}=\frac{150}{500}=0.3

Carnot efficiency is less than cycle thus it violates second law
