Answer:
When you toss a rolled up sock across the room, it travels faster as it becomes round and has more weight added on it and this causes the sock to travel in the direction you wish and this gives you a high chance of the sock going straight into the laundry basket, no matter how far away you are. 
On the other hand, throwing a sock without rolling it up will cause the sock to just flat down as you throw it. It will travel at a low speed because it has no weight on it since it is flat, and if you try to throw it, it will atleast land 21 cm away from you. About a 0% chance of it getting in the basket.
Hope this helped! => 
 
        
             
        
        
        
Since each student emits 100 W, so 170 students will emit:
total heat = 100 W * 170 = 17,000 W 
 
Convert minutes to seconds:
time = 50 min * (60 s / min) = 3000 s
 
The energy is therefore:
E = 17,000 W * 3000 s
<span>E = 51 x 10^6 J = 51 MJ</span>
 
        
             
        
        
        
Answer:
Without any external forces a moving object will continue to move in a straight line. The gravitational force between the two objects will provide the centripetal force to keep the objects moving around one another.
1. satellite in orbit around the earth             (motion of earth is negligible)
2. moon in orbit around the earth     (center of motion several thousand miles         
                                                              from center of earth)
3. earth in orbit around sun    (center of rotation close to center of sun)
4. binary stars         (if masses of stars are equal center of rotation is in middle)
 
        
             
        
        
        
The climate change can directly impact the formation of hurricanes because increasing temperature increases intensity of hurricanes.
<h3>How climate change could impact the formation of hurricanes?</h3>
Evaporation increases as temperatures rise which also causes the transfer of heat from the oceans to the atmosphere. As the storms travel across oceans whose water is warm, they absorb more water vapor and heat which increases rainfall as well as intensity of hurricanes.
So we can conclude that the climate change impacted the formation of hurricanes due to increasing temperature that increases intensity of hurricanes.
