Conduction is basically when hear is being transferred to another person/thing through the collision of particles nearby.
One example is when you snuggle with another person or thing such as an animal to keep warm. Heat is being transfer from that other person/thing body to yours.
Another example is when you hold a cold object for long such as a ice cube or a penny that was sitting on the counter for a while. The heat from your hands is conducted to the two objects and will melt the ice or if holding a penny, cause the penny to become warm.
Three ways to limit our exposure to radiation would be "time", "distance" and "shielding".
Time references how much time you're being exposed to the radiation. Example, in the sun. Limit the time you're outside. In an x-ray exam room, they try and get you out very quickly.
Distance references how close you are to the radiation. Again, in an x-ray room, they try and keep the radiation as far away from you.
Shielding would be to block yourself with lead (x-ray) or sunscreen (for sun exposure) to help protect you for further exposure.
Because people make those substance out of other things
1) False, an unbalanced force is needed or the object will stay in place.
2) True, weight is the amount of force gravity is putting on an object.
4) True, net force is equal to the mass of the object multiplied by the acceleration of an object.
5) False, however I'm not completely sure on this one.
6) Force is any interaction that will change the motion of an object.
7) vertical
8) horizontal
9) horizontal.
10) vertical or both.
A firework exploding is a chemical change as soon as you light the fuse the combustion reacts with the gunpowder.
