In an experiment, a student measures the speed of a toy car in locations K through N as it rolls down a ramp. Based on the data collected in the table, a conclusion was drawn by the student that unbalanced forces acting on the toy car affect its average speed. What reasoning led to the interpretation of this data and conclusion?
A) The average speed of the car decreases as distance traveled increases.
B) The average speed of the car increases as distance traveled increases.
C) The average speed of the car increases as the force of gravity decreases.
D) The average speed of the car decreases as the force of gravity increases.

Amachinist turns the power on to a grinding wheel, at rest, at time t = 0 s. the wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 96 rad/s. the wheel is run at that angular velocity for 40 s and then power is shut off. the wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. in this situation, the time interval of deceleration is closest to:

Calculate the minimum energy required to remove one proton from the nucleus 126c. this is called the proton-removal energy. (hint: find the difference between the mass of a 126c nucleus and the mass of a proton plus the mass of the nucleus formed when a proton is removed from 126c.) express your answer with the appropriate units. emin e m i n = nothing nothing request answer part b how does the proton-removal energy for 126c compare to the binding energy per nucleon for 126c, calculated using eb=(zmh+nmn−azm)c2?
