Answer:
If you were to inject air into space what would have happen?
Explanation:
In order for air to defy gravity, it would require atmospheric pressure. But air dosen't defy gravity unless it has the support of atmospheric pressure.

Answer:
The tension in the string connecting block 50 to block 51 is 50 N.
Explanation:
Given that,
Number of block = 100
Force = 100 N
let m be the mass of each block.
We need to calculate the net force acting on the 100th block
Using second law of newton



We need to calculate the tension in the string between blocks 99 and 100
Using formula of force


We need to calculate the total number of masses attached to the string
Using formula for mass


We need to calculate the tension in the string connecting block 50 to block 51
Using formula of tension

Put the value into the formula



Hence, The tension in the string connecting block 50 to block 51 is 50 N.

Answer:
E = 31.329 N/C.
Explanation:
The differential electric field  at the center of curvature of the arc is
 at the center of curvature of the arc is 
  <em>(we have a cosine because vertical components cancel, leaving only horizontal cosine components of E. )</em>
 <em>(we have a cosine because vertical components cancel, leaving only horizontal cosine components of E. )</em>
where  is the radius of curvature.
 is the radius of curvature. 
Now 
 ,
,
where  is the charge per unit length, and it has the value
 is the charge per unit length, and it has the value 

Thus, the electric field at the center of the curvature of the arc is: 


Now, we find  and
 and  . To do this we ask ourselves what fraction is the arc length  3.0 of the circumference of the circle:
. To do this we ask ourselves what fraction is the arc length  3.0 of the circumference of the circle: 

and this is  
 radians.
 radians.
Therefore, 

evaluating the integral, and putting in the numerical values  we get:
