what are the works of power which affect the mass?

Answer 1

#\text{Power}=12.635\ kW#

The power #P# of work on the block of mass #m=1400\ kg# moving with a constant velocity #v=1\ m/s# up the plane inclined at an angle #\theta=\tan^{-1}(3/4)# is given as
#P=\text{total force acting on the block down the plane}\times \text{velocity}#
#P=(mg\sin\theta+\mu mg\cos\theta) v#
#=mg(\sin\theta+mu\cos\theta)v#
#=(1400)(9.81)(3/5+(0.4) 4/5)\cdot 1#
#=12635.28 \ W#
#=12.635\ kW#

Works of power that affect the masses typically include political decisions, economic policies, social reforms, media influence, and cultural movements. These can shape public opinion, access to resources, social hierarchies, and overall quality of life for large populations. Examples include government legislation, corporate practices, advocacy campaigns, media narratives, and artistic expressions that impact the lives of many individuals within a society.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
