If the object is a square with sides of 3cm then the area is 0.0009 square metres.
We assume the pressure was measured on Earth's surface.
Weight (Newtons) = Pressure*area = (21 N/m2)*0.0009 m2 = 0.0189 Newtons.
The base area of 32 cm2 indicates the size, in terms of area, of the base of the object as 32 square centimetres. The height of 12 cm indicates that the perpendicular distance of the furtherst point of the object from the base is 12 centimetres.
Because Feck you, Goddamn cheating kids.
The answer depends on the object whose distance from Adrian is required.
perimeter (P)=2(length+base) find length, area = length * base = (p/2-base)*base
The two are related. The answer could be base 2, exponent 18 or base 8, exponent 6 or base 10, exponent 5.4185 or base 262144, exponent 1 or base 68,719,476,736 and exponent 0.5
If the area of the base is cut in half, then the pressure exerted by the object would double. This is because pressure is force divided by area, so reducing the base area by half would mean the force is now concentrated over a smaller area, resulting in higher pressure.
The line of action of weight is outside the base of the body.
The air pressure is greater at the base of the mountain compared to the peak. This is because the weight of the column of air above decreases as you move higher up in the atmosphere, leading to lower air pressure at higher elevations.
The weight and pressure is greater as the depth of water increases. The wide base is better able to withstand such forces. As the weight and pressure is less near the surface, the top of the dam wall doesn't need to be so wide.
The stability of an object can be increased by lowering its center of gravity, increasing its base of support, and adding weight to the base. Additionally, ensuring that the object is on a level surface and minimizing any external forces acting on it can also help improve stability.
The atmospheric pressure will be greater at the base of the mountain because pressure decreases with increasing altitude due to the weight of the overlying air. This means that as you climb higher up a mountain, the pressure will decrease.
As you move from the base to the top of a mountain, the air pressure decreases. This is because the weight of the air above decreases with elevation. At higher altitudes, there are fewer air molecules above, resulting in lower pressure.
Dams must hold back water of a certain depth, determined by the height of the dam. The pressure exerted by this water on the dam is dependent in part by its depth, since the base of the dam must be able to hold pressures exerted by the weight of all the water above the base. Since the pressure is greater at the base, the dam is broader at the base.
The tipping point of an object depends on factors like the shape, size, and weight distribution of the object. In general, the center of gravity needs to shift beyond the base of support for an object to fall when tipped. Objects with a lower center of gravity and wider base are less likely to fall when tipped compared to those with a higher center of gravity and narrower base.
Your center of gravity should be directly above your base of support when lifting an object to maintain balance and stability. This alignment helps distribute the weight of the object effectively through your body, reducing the risk of injury. Keeping your center of gravity over your base of support also helps you control the movement of the object more efficiently.
You need to know how high the water column is to calculate the pressure it exerts at its base! For example, a column of water 1 metre deep would exert a pressure of 9.81 kPa at its base (density x gravity x depth - 1000 * 9.81 * 1). This would be equal to approx 1.42 PSI.
Assumptions:Density of water = 1000 kgm-3.Gravitational acceleration = 9.81 ms-2To calculate the pressure head of a 1 m depth of water, it is necessary to find the unit weight:Unit Weight = Density x gravityUnit Weight = 9810 Nm-3To calculate the pressure head at the base of the column of water:Pressure = Unit Weight x DepthPressure = 9810 x 1Pressure = 9810 PaThe resulting pressure is 9.81 kPa.
