100points plzz me a glass rod with a silk cloth is an example of charging by
question 1 options:
conduction
induction
friction
question 2 (1 point)
rubbing a glass rod with a silk cloth will cause the rod to become more because it is losing electrons and the cloth to become more charged because it is gaining electrons.
question 2 options:
negatively; positively
positively ; neutral
positively ; negatively
neutral ; negatively
question 3 (1 point)
all matter is made up of both positive and negative charges, but we can only transfer the charges.
question 3 options:
positive
hyperactive
negative
neutral
question 4 (1 point)
charging by a method used to charge an object without actually touching the object to any other charged object.
question 4 options:
conditioning
conduction
friction
induction
question 5 (1 point)
when a charged object is brought near (without touching) a neutral object, this induces the electrons within the neutral object to move. this is an example of a temporary charge by
question 5 options:
condition
conduction
induction
friction
question 6 (1 point)
grounding allows charged objects to become neutral by electrons either flowing from the earth to the object or electrons flowing from the object to the earth through a conductor.
question 6 options:
true
false
question 7 (1 point)
when an uncharged student (standing on an insulating mat) touches a negatively charged van de graaff generator, this is an example of charging by
question 7 options:
conduction
friction
induction
condition
question 8 (1 point)
a positively charged object will be repelled by a negatively charged object because the charges are different.
question 8 options:
true
false
question 9 (1 point)
which of the following is an example of static electricity?
question 9 options:
current flowing through an outlet in your home
electrons moving from the battery through the wires to a light and back to the battery.
a build up of charges on a sock from a dryer

Some technological solutions to problems like global warming meet the specific needs and situations of local communities. an example from india involves converting the solid waste from cattle into clean-burning fuel for cooking. this reduces the amount of greenhouse gases, specifically methane and carbon dioxide, released into the environment from wood fires. when evaluating the feasibility of implementing this solution, computer models are used to weigh costs against benefits. what factor is least likely to impact the decision on adopting this technology?
