Explanation:
We know that momentum is the product of mass and velocity so
Mass (m) = 3 kg
velocity (v) = 3 m/s
Now
Momentum
= m * v
= 3 * 3
= 9 kg. m/s

Answer:
CHICKENPOX
Explanation:
Varicella-zoster virus (VZV) causes chickenpox and herpes zoster (shingles).
CHICKENPOX follows initial exposure to the virus.
After the chickenpox runs its course, the virus retreats to nerve tissues near the spinal cord and brain, where it hides out.
Reactivation of the dormant virus results in the characteristic painful dermatomal rash of HERPES ZOSTER, which is often followed by pain in the distribution of the rash (postherpetic neuralgia).
Reactivation can be due to:-
1) A weakened immune system, which can wake the virus up
2) Cancer, HIV, or another disease that lower your body’s immunity
3) Being 50 or older
4) Being under a lot of stress
5) Past physical trauma
6) Taking long-term steroids or other medications that can weaken your immune system.
