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.
Explanation:
The expression for the magnetic field around the current carrying wire is given by :
Here,
I is electric current and r is distance from the wire.
The factors affect the strength of magnetic field around current carrying wire are :
- Electric current
- Distance from wire
Answer:
a. Zombie
Explanation:
Zombies- A cracker — a computer hacker who intends mischief or harm — secretly infiltrates an unsuspecting victim’s computer and uses it to conduct illegal activities. The user generally remains unaware that his computer has been taken over — he can still use it, though it might slow down considerably. As his computer begins to either send out massive amounts of spam or attack Web pages, he becomes the focal point for any investigations involving his computer’s suspicious activities. In one case of zombies it was found that over 1.5 million computers were affected in an attack.
