The bottom of a box has a surface area of 58.8 cm 2 . The mass of the box is 12.0 kg. Acceleration due to gravity at sea level is 9.80 m/s 2 . What is the pressure exerted by the box where it rests

P = 20 kPa

Explanation:

Given that,

The surface area of the bottom of the box, A = 58.8 cm² = 0.00588 m²

The mass of the box, m = 12 kg

The acceleration due to gravity, g = 9.8 m/s²

We need to find the pressure exerted by the box where it rests. Oressure is equal to the force acting per unit area. So,

Pressure = Force/Area

So, the required pressure is 20 kPa.

- the Magnetic field lines will spread out of the north end of the magnet.

- the magnetic fields will three-dimensional and resemble a bubble.

Explanation:

- Usually, when drawing magnetic field lines, we start outwardly from the North pole to the South Pole. This same direction is also prevalent on the Earth due to the fact that the Earth functions as a giant magnet. Thus, one characteristic of the model is that the Magnetic field lines will spread out of the north end of the magnet.

- Another thing is that Magnetic field forces are usually driven as a result bubble like configuration which affects the objects that are in such a configuration. Thus, another characteristic of the model is that the magnetic fields will three-dimensional and resemble a bubble.
