Explain why an electric discharge occurs?
Because there is a potential difference between two objects.
When a pendulum swings the size of the swing gradually reduces with time until the pendulum stops explain how this can be possible if energy is conserved?
Energy is conserved in an isolated system, meaning since energy cannot be created or destroyed, the amount of energy in the system is the same. The point is, what is the 'system' in a certain scenario. Even if the pendulum was in an isolated room, that doesn't mean the pendulum will swing forever, because energy is constsntly lost to the environment, due to the friction with the air. But while energy is lost from the pendulum, energy is gained by the surrounding air molecules (also isolated), and thus energy in the system is conserved. Eventually the pendulum's kinetic energy will be zero, having lost too much to be able to make it move.
Do a stretched spring and a box on a high shelf both have potential energy why or why not explain you answer?
yes because is more
Explain how energy is conserved in the simple pendulum?
Remember the formula used to calculate the gravitational potential energy of a mass given its mass and height above an arbitrary zero level isPEgravity = mghWhen a pendulum is pulled back from equilibrium through an angle θ, its height is calculated with the formulah = L - L cos θwhere θ is the angular displacementThe formula used to calculate the kinetic energy of a massive particle isKE = ½ mv2In the absence of non-conservative forces, such as friction or applied, external forces, the mechanical energy in a system is conserved. That isDuring the swing of a simple pendulum, when does the bob possess maximum PE?PE is maximum at the endpoints (maximum amplitude)During the swing of a simple pendulum, when does the bob possess maximum KE?KE is maximum at equilibrium (bottom position)During the swing of a simple pendulum, what is the magnitude of the bob's maximum velocity?Another way of looking at conservation of energy is with the following energy diagram. As you can see,the "purple" curve represents the pendulum bob's KE which during each cycle begins with an initial value of zero, increases to a maximum value, and then returns to zerothe "green" curve represents the PE of the bob which begins each cycle at a maximum value, then becomes zero as the bob passes through its equilibrium position, and returns to its maximum valuethe "brown" line represents the total energy of the pendulum bob that always remains constantIf a pendulum is initially released at an angle of 37º, at what angle will its PE and the KE be equal?25.9ºRefer to the following information for the next question.At any intermediate position during the oscillation, the pendulum bob would have both PE and KE.PEmax = PEintermediate + KEintermediate = KEmaxIf the pendulum was released at point A, derive an expression for the pendulum's instantaneous velocity at point B, an intermediate position in its swing.See the related lesson on vertical circles if you are asked to calculate the tension of the string during the pendulum's oscillation. Remember that a pendulum is merely the bottom half of a vertical circle! These conservation of energy methods are the easiest way to determine an object's speed so that tensions can be calculated.
Explain how the maximum height is related to the maximum potential energy?
This question makes sense in the context of something like a pendulum. At the top of its swing, a pendulum is at maximum height, is not moving and so has zero kinetic energy, and has maximum potential energy since all its energy is potential. As it falls, it gradually moves with increasing speed, so its potential energy is being converted to kinetic energy. At the bottom of the swing, it is moving at maximum speed, and all its energy is kinetic, none is potential, Then it starts to move upwards again, and its kinetic energy is gradually converted back to potential energy.
Explain the process of preparing a detailed business plan?
Preparing a detailed business plan means researching various aspects of your potential business. You will need to determine exactly how you would market to customers and who you would hire for certain positions.
What is potential to growth internally and externally for business production?
explain the potential for growth of a business internally
What are positions of players in a volleyball team?
Well, it's kind of hard to explain, but the positions are not hard to learn, it depends on how many players are in the team.
Does the theory fully explain the positions of the continents today?
no.i think it doesnt.
Explain why scientists might use models to represent earth's processes?

Explain the energy conversions that occur as a pendulum swings and how does this demonstrate conservation of energy?
When the pendulum is at it's highest point in it's path of flight, the pendulum is not moving, and has purely potential energy. When the pendulum reaches the lowest point in it's flight, that potential energy is converted into kinetic. The total amount of energy has not changed though. Let's make up numbers to prove how this is true. Say we have a ball on the end of the pendulum that weighs 10kg. At it's max height, the ball reaches 5 meters above it's starting point. Since potential energy (PE) = mass (m) x gravity (g) x height (h), our PE = (5kg)(10m/s^2)(5m) = 250 Joules. As I mentioned earlier, total potential energy will equal the total kinetic energy (KE). When the ball reaches it's lowest point (where it's velocity is the highest), we can use our PE energy from the first equation to determine how fast the ball is moving at the bottom of the swing. KE = (1/2) x mass (m) x velocity (v) squared. Since KE also equals PE, we have 250 = (1/2)(5)(v^2) --> 100 = v^2. Therefore the veolcity equals 10 meters per second.

What will happens to the time period of simple pendulum if bob of the pendulum is completely immersed in water Explain?
Essentially , a simple pendulum is ignorant of air resistance, its more a tool to calculate gravitational acceleration, immersing it in liquid would introduce a drag force and bouyancy on the bob which alters the net force on the bob (essentially reducing the gravity)
