If it has a mass of 72 kg, then its weight on earth is 705.6 newtons (about 158.7 pounds). Its size, shape, color, fabric, contents, or the pressure it exerts on the ground don't matter. Consider this: If you set the suitcase down on its bottom, on one side, or on one end, its pressure on the ground would be different in each case, but its weight would not change.
"Tangent" to a circle means touching the circle at one point, and only one point. Think of a skinny bicycle wheel standing on the ground. The ground is 'tangent' to the wheel.
In order to walk from 15 below ground to 45 above ground, you have to climb a total of 60 floors.
The answer will depend on the tyre pressure and the mass of and in the Highlander.
In addition to the height of the object, the length of its shadow depends on a few other things that are not described in the question. -- Is the object standing straight upright ? -- Is the shadow cast on the ground or on sometheing else? -- If on the ground, is the ground level ? -- What is the altitude (angle) of the sun ?
The woman in high heels exerts more pressure on the ground because the pressure exerted is force divided by area; the smaller contact area of the heels concentrates the force, resulting in higher pressure. So, a 500N woman standing in 0.005m high heels exerts more pressure than a 500N woman standing in 0.05m work boots.
assuming they all weigh the same, they would be equal. if not, the heavier one would be exerting more pressure on the ground. if you are looking for an answer relating to pressure exerted in a specific spot, calculate it by surface area.
An ordinary human standing exerts a pressure equivalent to the body weight divided by the area in contact with the ground. On average, this pressure is about 10-15 pounds per square inch (psi).
The woman in high heels exerts more pressure on the ground because the weight of her body is distributed over a smaller area due to the small surface area of the heel compared to the work boots. This results in higher pressure on the ground beneath the heels.
The pressure exerted by a man standing on one leg depends on his weight, the surface area of his foot in contact with the ground, and the force distribution. Generally, the pressure will be higher when standing on one leg compared to standing on two legs because the force is concentrated on a smaller area.
in which situation you exert more force downward, standing or lying horizantilly?
it depends on the area
Yes, a pile of soil sitting on the ground exerts force on the ground beneath it. The soil has mass, and gravity pulls it down on the whatever is under it. A red ant standing atop the pile of soil exerts an extra force on it, to continue the figure.
The woman in high heels exerts more pressure on the ground because the smaller surface area of the heels concentrates her weight onto a smaller area, increasing the pressure. The work boots would distribute her weight over a larger surface area, resulting in less pressure on the ground.
There is more pressure when the man is standing, since pressure is the amount of force acting on a certain area and is calculated by dividing the force by the area. When a man is standing, the area of contact with the ground is less than the area of contact when lying down. Since his weight is constant, there is more pressure when he is standing.
The empty cardboard box exerts more pressure on the ground because its weight is concentrated on the bottom. When the cardboard is flattened for recycling, its weight is distributed over a larger area, reducing the pressure exerted on the ground.
The force the ground exerts on the moose is equal in magnitude but opposite in direction to the force the moose exerts on the ground. Therefore, the force exerted by the ground on the moose is also 3kN, assuming the moose is not accelerating vertically.
