A marble of mass of 10 g is placed on the track at the starting point. The height attained by the marble on the opposite side is measured. This is repeated five times.
Which of the following experimental results would support the conservation of energy
as it is explained in the reading?

Ireally just need to get finished with precal! i’m really sorry i have to do this! hope this !

We can infer that star y is closer but other factors must be considered including the heat of the star, the mass, and the brightness of the star. even though star x seems dimmer it may just be less bright or contain less heat.

Current supplied to consumers from generating plants like coal power plant, nuclear power plant, geothermal and others are in form of alternating current instead of direct current because it can be transported easily in a long distance. also, the alternating current has a wide range of frequency and the amount or energy can be increased or decreased.
