Answer:
The correct answer is - 4.34 days.
Explanation:
Given:
Distance from the sun to earth = 150 million kilometer
= 1500,00,000 km
The solar "wind" travels = 400 km/sec
= 400*60*60 km/ hour
= 1440000 km/hour
Then time = distance/speed
time = 1500,00,000 km/1440000 km/hour
time = 104.166666667 hours
time = 104.166666667/24
= 4.34 days.
Answer:
C
Explanation:
Many kinds of air pollution can't be seen, which means A is incorrect. Any kind of pollution can be harmful to you, which means B is incorrect too. Air pollution is very harmful but in most cases can't be directly seen, so C is correct. Pollution can be found everywhere, so D is incorrect also.
The "set-point theory" implies that each individual is genetically programmed to carry a particular amount of body weight.
The set point is the weight range in which your specific body is programmed to work. The set point theory trusts that a man's body will battle to keep up that specific weight range.
It is a sphere to be precise.
Because of the omnidirectional nature of the gravitational attraction, mass tends to form spheres in the macro scale of planets and similarly massive celestial bodies.
Both are used for energy to the body.
