Though it may not always be obvious, energy transfers and transformations constantly happen all around us and are what enable life as we know it to exist. There are three types of thermal energy transfer: conduction, radiation, and convection. Convection is a cyclical process that only occurs in fluids.

Refer to Activity 1: Describe the difference between the rate of diffusion seen for urea and albumin
raketka [301]

Answer:

the major difference between the rate of diffusion between urea and albumin is that urea diffused more slowly because it is larger than albumin.

Explanation:

As described in activity 1, the major difference between the rate of diffusion between urea and albumin is that urea diffused more slowly because it is larger than albumin. Urea basically is an heavy compound, thus it is at the base of the chain reactions  which which major purpose is to break down the amino acids that make up proteins. Albumin on the other hand is a form of protein that simply helps in the transmission of blood and prevent blood from flowing through to other tissue in the body. The liver produces the albumin the body. So going back to the question, the major difference between the rate of diffusion between urea and albumin is that urea diffused more slowly because it is larger than albumin.

A bat strikes a 0.145-kg baseball. Just before impact, the ball is traveling horizontally to the right at 43.0 m/s; when it leav
kotykmax [81]

Answer:

-7.352\times 10^3N

Explanation:

We are given that

Mass of baseball=m=0.145 kg

Initial velocity of ball=u=43 m/s

\theta=31^{\circ}

Speed, v=51 m/s

Time, t=1.71 ms=1.71\times 10^{-3} s

1 ms=1.71\times 10^{-3} s

Horizontal component of the average force on the ball=\frac{m(vcos\theta-u)}{t}

Horizontal component of the average force on the ball=\frac{0.145(-51cos31-43)}{1.71\times 10^{-3}}

Horizontal component of the average force on the ball=-7.352\times 10^3N

The water in a deep underground well is used as the cold resevoir of a Carnot heat pump that maintains the temperature of a hous
VMariaS [17]

Answer:

The temperature of well water be 288.07 K

Explanation:

We have given Heat in house Q_H=13900J

Work done W = 900 J

Efficiency is given by \eta =\frac{W}{Q_H}=\frac{900}{13900}=0.0647

Efficiency is also given by \eta =1-\frac{T_L}{T_H}, here T_L is lower temperature and T_H is higher temperature

So 0.0647=1-\frac{T_L}{T_H}

0.0647=1-\frac{T_L}{308}

T_L=288.07K

So the temperature of well water be 288.07 K
