Increasing its velocity will add to the kinetic energy more as the formula for kinetic energy is 0.5*m*v^2. (The speed will be squared making it greater)
What are the two sets? I only see the two answers?
Answer:
The action of rotating around something like for ex.. Child A stands in the middle of a room while Child B goes around Child A, Child B is rotating around Child A. Another ex. is; The earth rotates around the sun every 365 days the earth is rotating or going around the sun in a circle. So rotating to me is the act of rotating around something in any way shape or form.
PS: A middle schooler answered this so if you don't wanna believe me or think I'm wrong because I am younger you do you.
Answer:
the minimum value of torque is 101.7 N-m.
Explanation:
Given that,
Mass of bundle of shingles, m = 30 kg
Upward acceleration of the shingles,
The radius of the motor of the pulley, r = 0.3 m
Let T is the tension acting on the shingles when it is lifted up. It can be calculated as :
T-mg=ma
T=m(g+a)
Let 
is the minimum torque that the motor must be able to provide. It is given by :
the minimum value of torque is 
Yes, the first law of thermodynamics was created using the law of conservation of energy that is applied in a thermodynamic systems.the first law of thermodynamics is the change in internal energy of an
isolated system is equal to the amount of heat (Q) added to the system
minus the work (w) done by the system to the surroundings . while the law of conservation of energy states that in an isolated system that energy is constant, and energy can change its form but it cannot be created or destroyed.
