Un acróbata de 60 kg realiza un acto de equilibrio sobre un bastón. El extremo del bastón, en contacto con el piso, tiene un áre

vivado [14]

Answer:

Pressure, $P=6.39\times 10^6\ Pa$

Explanation:

A 60 kg acrobat performs a balancing act on a cane. The end of the cane, in contact with the floor, has an area of 0.92 cm2. Calculate the pressure the cane exerts on the floor (neglect the weight of the cane).

We have,

Mass of acrobat, m = 60 kg

The end of the cane, in contact with the floor, has an area of, $A=0.92\ cm^2=0.92\times 10^{-4}\ m^2$

It is required to find the the pressure the cane exerts on the floor. Pressure exerted by an object is defined as the force acting per unit its area. Its formula is written as :

$P=\dfrac{F}{A}\\\\P=\dfrac{mg}{A}\\\\P=\dfrac{60\times 9.8}{0.92\times 10^{-4}}\\\\P=6.39\times 10^6\ Pa$

So, the pressure the cane exerts on the floor is $6.39\times 10^6\ Pa$ .

How to calculate percent error

olga_2 [115]

Answer:

Steps to Calculate the Percent Error

Subtract the accepted value from the experimental value.

Take the absolute value of step 1.

Divide that answer by the accepted value.

Multiply that answer by 100 and add the % symbol to express the answer as a percentage.

In which direction does the magnetic field in the center of the coil point?

RSB [31]

Each segment of circular loop carrying current produces magnetic field lines in the same direction with in the loop. The direction of magnetic field at the centre of circular coil is perpendicular to the place of the coil. i.e. along the axis of the coil. Please mark brainiest!!!
