Answer:
70.7m/s
Explanation:
V = ( v + u)
_____
2
V = average velocity
v = final velocity
u = initial velocity
velocity = distance
______
time
u (initial velocity) = 33 ÷ 2
change mins to seconds
1 min = 60 secs
2 mins = ?
cross multiply
60 × 2 = 120 secs
u = 33 ÷ 120
u = 0.275m/s
v ( final velocity) = 29 ÷ 1.3
change mins to secs
1 min = 60 secs
1.3 mins = ?
cross multiply
1.3 × 60 = 78 secs
v = 29 ÷ 78
v = 0.371 m/s
V = ( v + u )
_____
2
V = ( 0.371 + 0.275)
____________
2
V = 0.51 m/s
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.
