(a) The work done by the person is 18.83465 kJ.

(b) The average power performed by the person during the walk is 51.4 W.

(c) The amount of food calories burnt is 4.5 Cal.

<h3>Work done by the person</h3>

The work done by the person is calculated as follows;

W = Fd

W = mgh

W = (89.2 x 9.8) x (0.162 x 133)

W = 18,834.65 J

W = 18.83465 kJ

<h3>Average power of the person</h3>

P = Fv

where;

  • v is velocity

v = (d)/t

v = (133 x 0.162)/(6 x 60   +  6)

v = (133 x 0.162)/(366)

v = 0.0588 m/s

P = (89.2 x 9.8) x 0.0588

P = 51.4 W

<h3>Amount of food calories burnt</h3>

4.1868 kJ = 1 Cal

18.83465 kJ = ?

= 4.5 Cal

An airplane with constant speed 696 mph than another 40 minutes constant speed 804 mph what is distance it go?
sleet_krkn [62]

Answer:

536 miles

Explanation:

If the airplane is running at a speed of 804 miles per hour, and covers a distance, x in a particular number of mile. The distance in mile can be gotten they the application of direct formula. Multiplying the speed by the time it took, and thus

804 mph * 40

Remember the time is in minutes and not hours, so, you convert it to hours.

804 * 40/60 hours =

536 miles

Imagine that you are sitting in a chamber with your back to one wall. An electron beam, moving horizontally from the front wall
Allisa [31]

Answer:

Flemmings' left hand rule  and Downward direction

Explanation:

The person could able to determine the path of force by applying the left-hand rule of Fleming.

Via holding the thumb the forefinger and second finger at right angles for one other

The left-hand rule is applied in the electric motors

On the other hand, the right-hand rule is applied for electric generators.

So different hands are used for the different thing as there is a difference between the cause and effect

Therefore in this case there is a left hand rule used and the direction is downward
