Brown middle school is trying to become a "green school". to do this, parents, faculty and staff members are meeting to discuss ways to reduce their use of non-renewable natural resources, overall. after reviewing the government data in science classes, the faculty has asked for input from students.
a list of good ideas was generated. all but one would be an excellent tactic to include in the school's plan to conserve resources. that is a) turn off lights when a room is not infuse.
b) turn on computers and office equipment only when needed.
c) rely more on natural lighting instead of electric lights.
d) ask students and staff to bundle up and turn off the heat.

The force needed to overcome static friction is usually less than that needed to overcome kinetic friction.true or false?

3. a worker pushes a 30.5 kg polished stone along a polished table with a force on bonin a straight line for 5.20 s after starting from rest. there is no friction between thestone and the table. at the end of the table. the stone is hooked to a cable with a lengthof 62.0 cm to rotate it to a rough table to store until they can be picked up. the roughtable has a coefficient of static friction 0.702 with the polished stone. remember that 8= 9.80 m/s2a) what is the speed of the stone when it is hooked to the cable? b) what is the tension in the cable while the stone is rotating? (there is still nofriction)c) how much force is needed to make the stone begin sliding from rest on therough table? ius = 0.70262.0 cm30.5 kg20.5 kg6= 0
