<span>So we are wondering what would describe lightning most accurately: Alternating current, Direct current, Static electricity or static discharge. The most similar phenomenon to lightning would be static electricity sparks which happen when we have enormous quantity of charge. So D would be the correct answer.</span>
Answer:
Explanation:
Given
launch velocity 
Launch angle 
Range of Projectile 


Horizontal velocity remain same and only vertical velocity changes.
Initially vertical velocity is in upward direction but as soon as it reaches the ground its direction change but magnitude remain same.



The higher the sea surface temperature, the faster the warm, moist air rises into the atmosphere. This updraft creates a donut shaped vortex that is rising in the middle and going downward on the sides. The more moisture in the air (humidity), the stronger the vortex will become as the moisture rises through convective currents, cools, and falls through convective currents. This eventually causes rotation of the storm mass and you get a tropical cyclone. So, the high sea surface temperatures and humidity are actually the engine that forms a hurricane and causes it to increase in strength.
High level horizontal winds can prevent a hurricane from forming. These are called shear winds and they literally blow the top of the cyclone off, preventing it from forming properly.
The Normal Force = M x G x Cos(theta)
= 9.5 Kg x 9.8 m/s^2 x cos 23
= 9.5 Kg x 9.8 m/s^2 x 0.9205
Converting Kg to Newton,
1 Kg = 9.81 N
= 9.5 Kg x 9.81 N x 9.8 m/s^2 x 0.9205
= 840.702 N
The NUCLEUS is the center of the atom. it contains protons and NEUTRONS
protons have a POSITIVE charge
neutrons have a NEUTRAL charge
electrons have a NEGATIVE charge
