Answer:
B) 1218
Explanation:
N = Total number of turns in the solenoid 
L = length of the solenoid = 34.00 cm = 0.34 m 
B = magnetic field at the center of the solenoid = 9 mT = 9 x 10⁻³ T
i = current carried by the solenoid = 2.000 A 
Magnetic field at the center of the solenoid is given as 


N = 1218
 
        
                    
             
        
        
        
<span>Without plate tectonics, new mountain belts could not form. Earth would be a Waterworld with occasional shield volcanoes emerging briefly above the waves. If regular catastrophic convective overturn occurred, as on Venus, life would have a precarious foothold indeed.

The horizontal component of velocity is
(22 m/s) • cosine(62°).
The vertical component of velocity is
(22 m/s) • sine(62°).
These are the original components, right after the kick. As time goes on, the horizontal one doesn't change. But the vertical one gets bigger and bigger, because gravity is accelerating the ball downward.
That's the complete story of projectile motion.
