Scanning at the resolution required to determine the details of individual synapses would requires a field strength high enough to cook a person's tissues.

以确定单个突触细节所需的分辨率进行扫描将需要足够高的场强以制造人的组织。

Its magnitude equals the mass  of the fluid displaced by the object times the gravitational field strength hold up, mass times  acceleration due to gravity?

它的大小等于物体排出的流体质量乘以引力场强度，质量乘以重力加速度？

Now we have net force equals density of the fluid times gravitational  field strength times area of one side of the cube times the length of one side of the cube.

现在我们有净力等于流体的密度乘以重力场强度乘以立方体一侧的面积乘以立方体一侧的长度。

I will add that the composition of the object  which is submerged in the fluid does not affect the buoyant force, only mass of the fluid  displaced by the object and the gravitational field strength determine the buoyant force.

我要补充一点， 浸没在流体中的物体的成分不会影响浮力，只有物体位移的流体质量和重力场强度决定了浮力。
