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
Answer:
By using observations from the Atacama Cosmology Telescope (ACT) in Chile, the new findings match the measurements of the Planck satellite data of the same ancient light.
Explanation:
Explanation:
A circuit breaker is an automatic switch that cut off current in a circuit when the current become too large. When the current in a circuit increases, the strength of the electromagnet will increase in accordance; this will pull the soft iron armature towards the electromagnet.
