Aim:To investigate the conservation of kinetic energy and the conservation of momentum in an oblique collisions between two objects. Hypothesis: By law of conservation the momentum and kinetic energy should be conserved in an oblique collision between two objects however in our case I hypothesize there will be a slight difference due to the fact that the system is not isolated and forces from outside will act upon it

Variation of current through the windings of insulated wire affect the strength in the electromagnet
(527 words) , Download 55 , Essay
Only on istudyhub
Research Question: How does a variation of current through the windings of insulated wire affect the strength in the electromagnet? Key Variables: Variable: Current (depends on the input voltage of the power kit) Constants: Length of the winding wire, Number of turns, Permeability (depends on the insulation around the wire and the physical properties (composition, diameter, length) of the nail) Hypothesis: If we double the current, then the strength in the electromagnet should also double. Rccording to the magnetic field strength equation, , the flux density B inside the solenoid is directly proportional to the current I
