Answer:
75% is the efficency of this maxhine
Answer:
286.7 m
Explanation:
So we are assuming the PE of the falcon is converted to KE
KE = PE
1/2 (.480)(75)^2 = .480 (9.81)(h ) solve for h = 286.7 m
Answer:
For A
Displacement= 1/2*3*6= 9m
For B
Displacement= 1/2*4*4= 8m
Answer:
Insulation helps to prevent that transfer of heat.
