The energy content of food is conventionally measured in Calories rather than joules. One Calorie in nutrition is equal to 4184

Rama09 [41]

Answer:

Part a)

$P = 186 W$

Part B)

$N = 676 times$

Explanation:

Part a)

Average power is rate of energy consumption

So it is given as

$P = \frac{mgh}{t}$

$P = \frac{100(75.7)(9.81)(0.150)}{59.9}$

$P = 186 W$

Part b)

If the efficiency is given as

$\eta = 20$ %

so we know that 20% of total energy consumed is converted into output work

So total power consumed here will be given as

$P = \frac{186}{0.20}$

$P = 930 W$

Energy consumed by him

$E = power \times time$

$E = 930 \times 59.9$

$E = 55707 J$

now we know that 1 g fat will release 9 Calories energy

So we have

$1 g = 9 \times 4184 J$

$1 g = 37656 J$

so to consume 1000 g of fat we need to release total energy

$E = 37656 \times 10^3 J$

so total number of times

$N = \frac{37656 \times 10^3}{55707}$

$N = 676 times$

What is the mean height for the grass used as a control?

motikmotik

The mean height for the grass used as a control is equal to the total number of the data came from the control grass divided by the number of control grass in the experiment. The mean height means the average height of the grass.

A client with a head injury is being monitored for increased intracranial pressure (ICP). The client's blood pressure is 90/60 m

artcher [175]

Answer:

$CPP=52mm \ Hg$

Explanation:

Cerebral Perfusion Pressure is obtained by subtracting IntraCranial Pressure(ICP) from the Mean Arterial Pressure(MAP). Adequate cerebral perfusion requires a minimum goal of $70mm \ Hg$ . MAP is obtained using the formula:-

$MAP=\frac{(diastolic \ blood \ pressure\times2)+\ systolic \ blood \ pressure)}{3}\\\\MAP=\frac{2\times60+90}{3}\\\\MAP=70mm \ Hg\\CPP=MAP-ICP\\CPP=70-18\\CPP=52mm \ Hg$

a) If a proton moved from a location with a 5.0 V potential to a location with 7.5 V potential, would its potential energy incre

tekilochka [14]

Answer:

A. The potential energy of the positively charge proton from 5v to 7.5v will increase because in an electric field work is done on the proton to move it to a point of higher potential

B. when an electron is moved from 7.5v to 5v it loses potential energy due to the charges lost so as to bring it to a point of lower potential
