25. A student wants to perform an experiment where they have to measure the time interval for a ball bearing rolling down a slope (as with your first practical), in order to determine the acceleration on the ball-bearing. They take 1 measurement for every distance (they move the end of the measuring equipment 10 cm further way every time), and then they plot a graph. This graph comes out with very scattered values that do not form a straight line at all. What could be the reason for this? Choose all correct answers. A. They should have taken more than one measurement at every distance. B. The stopping wires might have malfunctioned sometimes, so they should have made sure that the stopping wires only touched the metal when the ball bearing rolled over it. C. The graph is fine with only one value measured per distance. It is the acceleration that was not consistent. Nothing needs to be changed. D. The graph axes need to be adjusted to make the data show a straight line.

The graph to the right shows velocity vs. time for a cart on a track with a friction pad attached. The cart was launched from rest by a hoop spring. Use this graph to answer the following question: so long as the ramp is level, even with the friction pad NOT in contact with the track it is impossible to produce a region "b" that is flat (horizontal), i.e. that shows a constant velocity. This is because b V a of errors inherent to the motion detector the acceler tion gravity causes the cart to rate air currents in the room significantly affect the motion of the cart there is still a small amount of friction between the wheels of the cart and the track, and the axels of the cart with the body of the cart achieving constant velocity is not physically realistic under any circumstances
An inclined straight line in an s-t graph means: The object is not in motion. Velocity is constant. Acceleration is constant. Erratic motion takes place.

1. The wheel starts rotating from rest, 2) if its angular velocity Was a function of angular position 0 is W=0.1-0², where O is in radian, and its radius ris 0.2 m, what is the magnitude of the angular acceleration (in rad/s?) of the wheel after the wheel has turned 1.1 revolution(s) from rest. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point. P
As the potential across the resistor increased, the current through the resistor increased. If the change in current is proportional to the voltage, the data should be in a straight line and it should go through zero. In these two examples how close is the y-intercept to zero? Is there a proportional relationship between voltage and current? If so, write the equation for each run in the form potential = constant x current. (Use a numerical value for the constant.)
Posted below is a picture of a data table and a diagram of an experiment. In the experiment you rolled a marble down a ruler ramp off the end of a coffee table to observe projectiles and conservation of energy. You do 3 trials for each initial height. Each height is measured in meters. h= initial height of marble off of table Y= height of table off floor X= horizontal distance marble goes from edge of table to where it strikes the floor a) use the table to find information you need to solve for theoretical range and % of error in measured range.
Please make the code for this graph and make sure it comes up the same. I need help making this.
