A. Buoyant force = density of fluid * volume of fluid displaced * gravitational acceleration. B. Buoyant force = weight of the object * volume of the object. C. Buoyant force = density of the object * volume of the object * gravitational acceleration. D. Buoyant force = weight of the ...
I propose that buoyant force be generally defined as the negative of the total weight of the fluids that are displaced, rather than as the net force exerted by fluid pressures on the surface of an object. In the case of a body fully surrounded by fluids, these two definitions are equivalen...

A. The object will sink. B. The object will float. C. The object will stay in the same place. D. The object will disappear. 相关知识点: 试题来源: 解析 B。中文解析:“If the buoyant force is greater than the weight of the object, the object will float.”。 反馈...
What is the upthrust equation?Question:What is the upthrust equation?Upthrust or Buoyant Force:The concept of the buoyant force on a body submerged in a fluid is explained by Archimedes' principle. According to this principle, the buoyant force exerted on a body immersed in a fluid is equal...
A 1.5 kg block displaces 4.0 kg of water when it is held fully immersed. What is the buoyant force? A. Calculate the buoyant force. B. What is the specific gravity of the object if the fluid is water? If your weight is 300 N, what is the upthrust on you when you are floating ...
解析 B。解析:文章中提到“When an object is placed in water, it experiences an upward force called buoyant force. If the buoyant force is greater than the weight of the object, the object will float.”,所以使物体漂浮的力是浮力。反馈 收藏 ...
That means that the more force you apply to an object, the greater the acceleration. And, the more mass the object has, the lower the acceleration. Newton's Second Law can be written in equation form: F = ma. For falling objects we can write F=mg where g is the acceleration due to...
To determine the direction of the buoyant force on an object immersed in a liquid, we can follow these steps:1. Understanding Buoyant Force: - Buoyant force is the upward force exerted by a fluid on an object that is submer
