Johanna carries out an investigation where she uses a motor to lift different masses. She calculates the amount of energy transferred to a gravitational
potential energy store when the mass moves up and uses an energy meter to
measure the amount of energy transferred electrically by the motor.
а In one trial she calculates that the energy in the gravitational potential
store is 1.2 J. When she uses the motor to lift the mass she finds that the
energy meter gives a reading of 2.3).

you would have to sell 24 bracelets.

step-by-step explanation:

84/3.5 = 24

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
