Earth is 150 million kilometers from the sun, and the solar "wind" travels at about 400 km/sec. How long does it take particles
FrozenT [24]

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.

<em>The correct option is d) distal humerus fracture</em>

The humerus is one of the three bones which join to make up the elbow joint. A break in the lower end part of the upper elbow results in distal humerus fracture. Such types of events are caused due to high energy collisions such as during an accident. The distal humerus fracture can be treated through a surgery. During the surgery, the normal motion of the humerus is tried to be restored.
