Energy Basics:Question 1 The diagram shows a cart at four positions as it moves
along its track. At which positions is the sum of the potential
energy and kinetic energy of the cart the same?
Select one:
BY
A and B, only
O Cand D, only
all positions, A through D
B and C, only

The sum of the kinetic and potential energies are equal at points B and C, only

Mechanical energy refers to energy that is possessed by a body either as a result of its motion or as a result of its position. There are two forms of mechanical energy;

Kinetic energy refers to energy possessed by a body by virtue of its motion while the potential energy is energy possessed by a body by virtue of its position. Looking at the image, the sum of the kinetic and potential energies are equal at points B and C, only

Step-by-step explanation:

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
