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:
q = - 93.334 nC
Explanation:
GIVEN DATA:
Radius of ring 73 cm
charge on ring 610 nC
ELECTRIC FIELD p FROM CENTRE IS AT 70 CM
E = 2000 N/C
Electric field due tor ring is guiven as
![E = \frac{KQx}{[x^2+ R^2]^{3/2}}](https://tex.z-dn.net/?f=E%20%3D%20%5Cfrac%7BKQx%7D%7B%5Bx%5E2%2B%20R%5E2%5D%5E%7B3%2F2%7D%7D)
E1 = 3714.672 N/C
electric field due to point charge q
now the eelctric charge at point P is
E = E1 + E2
solving for q
q = - 93.334 nC
Answer:
The molecules in a solid are all packed together and vibrating.
The molecules in a liquid are able to fit into a space, because they aren't packed together, they are more apart from each other.
The molecules in a gas are even further apart from each other, and able to move way more freely.
Explanation:
Solid things are solid because of the molecules being so packed together.
Liquid things are liquid because of there being not as many in one space, it's more spread out.
Gas things are gas because of the molecules moving fast and there aren't as many so it's more spread out than other things.
I hope this helped!
