Answer:

SHUTTER speed - no longer shudder !!!!!! would be a placing on your camcorder - examine the handbook - verify interior the camcorder menu - let us know what digital camera you have possibly somebody else has one and can permit you comprehend.
Bubble wrap is a good thermal insulator, because air isThe air trapped in the bubbles are actully why it insulates so wellIf you put it so the bubbles are inwards and the flat side is outwards, this helps trap more air around the object and makes it a little more effective stillAluminium foil on the outside of a thermos made for a project will help reflect any radiated heat backHeat is trasferred by three methods: 1Conduction 2Convection 3Radiation Conduction is where you heat one end of a metal rod and the other end gets hot as wellThis is because the metal is conducting the heat away from the hot endConvection is where heat travels (typically through the air in a room)The heated air is less dense and so risesThe colder air then flows in at the bottom, until it gets heated and rises in turnConvection takes place in waterYou can actually see waves sometimes in water if you look into an electric kettle soon after it is turned onRadiation is where heat is trasmitted by elecro-magnetic radiation (infra-red)Stand by an fire and you can feel the heat from itPut a sheet of card infront of you and you can no longer feel the heatThis is because the card is stopping the infra-red light from reaching youI hope this helps?!
