the radii of the circles i, i0, and t give an estimate of the error in your experimental values for each of the horizontal ranges. using this estimate of uncertainty, what is the fractional uncertainty in each distance measurement? how do these uncertainties compare with the percent differences between the initial and final values of the kinetic energy, between the initial and final values of the x-component of the total momentum, and between the final y-components of the two balls?

i believe it is b. what was the cause of the big bang

hope this !

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
