Answer:
4.33m
Explanation:
Power = work done/ time
work done = power × time =650 × 2 = 1300J
work done = force × distance
distance = work done/force
distance = 1300/300 = 4.33m
I believe that your answer is true
Answer:
Plumbing appliance
Explanation:
Plumbing appliance are instrument connected to a water source in order to perform specific plumbing function, this instrument has it operation or control dependent on more energized component such as control or heating element, motor etc. some example of plumbing appliances are water heater, washing machine etc.
Answer:
511.1 J
Explanation:
We are given that
Mass of wood block=m=3 kg
Vertical distance,h=23 m
Horizontal distance =x=30 m
Distance traveled in downward direction y=40 m
Initial velocity,u=0

Where 






By work energy theorem
Change in kinetic energy=Work done= mgh-W



Hence, the work done due to friction on the block as it slides down the ramp=511.1 J
