Phase 1: A virus in animals has caused no known infections in humans.<span>Phase 2: An animal flu virus has caused infection in humans.</span><span>Phase 3: Sporadic cases or small clusters of disease occur in humans. Human-to-human transmission, if any, is insufficient to cause community-level outbreaks.</span><span>Phase 4: The risk for a pandemic is greatly increased but not certain.</span><span>Phase 5: Spread of disease between humans is occurring in more than one country of one WHO region.</span><span>Phase 6: Community-level outbreaks are in at least one additional country in a different WHO region from phase 5. A global pandemic is under way.</span>
How many people die from a pandemic depends upon:
<span>The number of people who become infectedThe severity of disease caused by the virus (its virulence)The vulnerability of affected populations<span>The effectiveness of preventive steps

Answer:
The rate of heat transfer of the second object is greater than the first object.
Explanation:
= Emissivity of the object
= Stefan-Boltzmann constant =
= Temperature of surface 1 =
= Temperature of surface 2 =
= Surrounding temperature =
Rate of heat transfer is given by
So,
Hence, the rate of heat transfer of the second object is greater than the first object.
Answer:
forces acting on the two will be equal and opposite in nature according to Newton's third law of motion.
Explanation:
Given:
mass of Karen, (let)
then, mass of Bill,
When they are standing near one another and suddenly Bill pushes Karen then this can be treated as elastic collision and the conservation of momentum applies as:
Sum of final and initial momentum of the system is zero.
But the forces acting on the two will be equal and opposite in nature according to Newton's third law of motion.
