Answer:
because
Explanation:
streasm dont flow horizontal because if it did then that would be breaking all laws of physics and we know that what goes up must com down but water cant flow upstream only down if it does flow horizontally then it would either be between two hills or in a plains 
 
        
             
        
        
        
Answer:
 the greater the speed, the greater the electromotive force
* The metal pole must be parallel to the field
* you must keep the ball of the field
Explanation:
To determine the advice to the runners, let's use the Farad equation to and
            fem = -N  = -N
  = -N  
how the runners are moving
                  fi = B l x
             fem = -N B l v
therefore the advice we can give are:
* the greater the speed, the greater the electromotive force
* The metal pole must be parallel to the field
* you must keep the ball of the field
 
        
             
        
        
        
D is correct answer.Momentum it depends to acceleration and velocity, and inertia only depends on velocity.
Hope it helped.

Answer:
Magnitude of electric field is 1.06 x  V/m along negative X-direction
 V/m along negative X-direction
Explanation:
Given: initial velocity of proton = u = 3.5 x  m/s
 m/s 
final velocity of proton = v = 0 m/s 
initial point  = 0.2 m and final point is
 = 0.2 m and final point is  = 0.8 m
 = 0.8 m
According to conservation of energy:
change in in kinetic energy = change in potential energy of proton 
⇒ 
 
where q and m is the charge and mass of proton E is the electric field ,  and
 and  is the initial and final position of proton
 is the initial and final position of proton
on substituting the respected values we get,
1.023 x  = 9.6 x
 = 9.6 x  x E
 x E
⇒ E = 1.06 x  V/m
 V/m
external force is opposite to the motion as velocity of proton decreases with distance.
Therefore, magnitude of electric field is 1.06 x  V/m along negative X-direction
 V/m along negative X-direction
 
        
             
        
        
        
Answer:
Mark me as brain list plz 
Explanation:
Using Bernoulli's Theorem 
1/2 V12 +P1/d = 1/2V22 +P2/d 
V1 = 17.4
V2 =0
1 /2 V12 = Pressure Difference / d 
Where d = Density of air 
Pressure Difference =( 1/2 V12) Density of air
Pressure Difference = 369.36
Force = Pressure difference * area = 369.36 *3.5 = 1292.8 N
