Answer:

Explanation:
given,
86 out of every 100 TV households have at least one remote control
Probability of any material is calculated by.



now, Calculating probability that at least one remote control
q = 1 - 0.86
q = 0.14


As Potential energy =mgh
m= 0.95kg
h=3 meter
g = 9.8 m/sec^2. ( acceleration due to gravity)
So P.E =(0.95)(9.8)(3)kgm^2/s^2
P.E =27.93 joules
Answer:
the two factors are the mass of the objects and the coefficient of friction between them
Explanation:

Answer:
The work done by gravity is 
Explanation:
The data given in the question is :
Mass is 
Height from ground is 
As we know , the work done is state function , it depends on initial and final position not on the path followed.
So, work done by gravity = change in potential energy
Work done = Initial potential energy - final potential energy
Insert values from question
Work done = 
Work done = 
So, work done = 
Hence the work done by gravity is
