Question 3 of 15 A reaction occurs in which a uranium-238 atom forms a thorium-234 atom
and a helium-4 atom. Is this a chemical reaction or a nuclear reaction, and
how do you know?
A. A nuclear reaction, because one reactant became two products.
B. A nuclear reaction, because there was a change in the original
atom's nucleus.
O C. A chemical reaction, because two products formed from one
reactant.
O D. A chemical reaction, because there was a rearrangement of the
atom's electrons.

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)

Consider two less-than-desirable options. in the first you are driving 30 mph and crash head-on into an identical car also going 30 mph. in the second option you are driving 30 mph and crash head-on into a stationary brick wall. in neither case does your car bounce off the thing it hits, and the collision time is the same in both cases. which of these two situations would result in the greatest impact force?
