harmless, a sheet of paper
Alpha particles do not possess a high amount of energy and are not very ionizing, since they have a high mass. This makes them relatively safer to work with.
Answer:
kinetic energy
Explanation:
because it is at the top going down

Answer: For #1 scientists look for physical characteristics that are like Earth its self. These characteristics include water, rocks and other complex chemistry that can support life.
Explanation:
Explanation : When the lift falls, then the gravitational energy changed into the kinetic energy. Gravitational potential is associated with the mass of the lift and its position. When lift starts from rest , the mechanical energy of the lift change in the form of potential energy.
When the lift down than the potential energy lost and kinetic energy is gained. Lift loses height and gains speed.
The work is performed by the lift, when lift covers the distance against the gravitational force.
