Apendulum consists of a 2 kg bob attached to a light string of length 3 m. the bob is struck horizontally so that it has an initial horizontal velocity of 4.1 m/s. for the point at which the string makes an angle of 30° with the vertical, calculate the following: (a) the /s)(b) the gravitational potential energy (relative to its value is at the lowest )(c) the tension in the )(d) what is the angle of the string with the vertical when the bob reaches its greatest )

Iwould sure like to answer your question but i honestly just don’t know

There is no graph to look at on here, but i shall explain them to you. a line graph is just in its title it’s a graph with a line running through the dots to show an increase or decrease. a bar graph is used to show how much or how little something is so a comparison. a scatter plot is used to graph points to tell the data. and i don’t know what a histogram is.

Multiply the 3 dimensions, assuming it is a rectangular cuboid, to get the volume in cm³ divide mass by volume to get density in g/cm³

Ohm's law tells you that i = v/r where v is equivalent voltage and r is equivalent resistance of the circuit
since all circuits have the same voltage, your question is really asking which circuit has the lowest total resistance, since the lower the resistance, the higher the current
circuit a has a resistance of 5 ohms; circuit c is in series so has a resistance of 10 ohms; circuit b is in parallel and therefore has a resistance of 2.5 ohms (review your notes on adding resistances in parallel and series); therefore b has the highest current
