Answer: Liquid
“A substance will take on the shape of an open container if it is a Liquid. Explanation: The major state of matter are solid, liquid and gas. Liquid usually have a definite volume.”
Use the velocity expression for uniform acceleration and solve for t: v = v0 + at. v0 is zero since the object is at rest. 49 m/s = a(t), and solve for t. t = 49 m/s / 9.8 = 5 seconds.
The electric field due to a point charge of 20uC at a distance of 1 meter away from it is 180000 
.
First, you have to know that the space surrounding a load suffers some kind of disturbance, since a load located in that space will suffer a force. The disturbance that this charge creates around it is called an electric field.
In other words, an electric field exists in a certain region of space if, when introducing a charge called witness charge or test charge, it undergoes the action of an electric force.
The electric field E created by the point charge q at any point P, located at a distance r, is defined as:
where K is the constant of Coulomb's law.
In this case, you know:
- K= 9×10⁹
- q= 20 uC=20×10⁻⁶ C
- r= 1 m
Replacing in the definition of electric field:
Solving:
<u><em>E=180000 </em></u><u><em /></u>
Finally, the electric field due to a point charge of 20uC at a distance of 1 meter away from it is 180000 .

When the magnitude of all opposing forces is equal, then the force is called balanced. The forces on W and Y are balanced while the forces on X and Z are unbalanced.
<h2>
Net Force:</h2>
It is defined as the vector sum of all forces acting on the object. The forces with the same magnitude in the opposite direction cancel each other.
<h3>Balanced force: </h3>
When the magnitude of all opposing forces is equal, then the force is called balanced.
<h3>Unbalanced force: </h3>
When a force is more than the opposing force, the force is called unbalanced.
Therefore, the forces on W and Y are balanced while the forces on X and Z are unbalanced.
