Answer:
The acceleration is 2.448 meters per square second and is vertically upward.
Explanation:
The Free Body Diagram of the plastic ball in the liquid is presented in the image attached below. By Second Newton's Law, we know that forces acting on the plastic ball is:
(1)
Where:
- Buoyant force, measured in newtons.
- Mass of the plastic ball, measured in kilograms.
- Gravitational acceleration, measured in meters per square second.
- Net acceleration, measured in meters per square second.
If we know that 
, 
and 
, then the net acceleration of the plastic ball is:
The acceleration is 2.448 meters per square second and is vertically upward.
Answer:
Explanation:
Let establish a control volume in the industrial pressure cooker, which is a transient state system. From the First Law of Thermodynamics, the heating process is modelled:
The heat transfered to the cooker is:
Properties at each state are described below:
State 1
State 2
The heat transfered to the cooker is:
Answer:
142m/s2
Explanation:
The solution is in the attached file below
<span>The amount of kinetic energy an object has depends on its "speed." Kinetic energy is energy a object has while its in motion so the key word is speed.
