Scientists have studied two species of sand lizards, the Mojave fringe-toed lizard and the western zebra-tailed
lizard, to understand the extent to which the different
structure of the two species' toes is related to their
preferred habitats-fine sand for the Mojave lizard and
coarse sand for the zebra-tailed lizard. (Figure 1)
shows a somewhat simplified velocity-versus-time
graph for the Mojave fringe-toed lizard. Examine the maximum acceleration of the lizard in both m/s^2, and g’s. estimate it’s acceleration at t=150ms

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.

the only real purpose of sputnik 1 was to beat the us into space. we were getting close to launching a useful satellite, explorer 1 - which launched on january 31, 1958. the ussr had to beat that, so they launched sputnik 1 on october 4, 19
