Select the correct answer. If the cross-sectional area of a wire is decreased while all other factors remain the same, how will the resistance change? А. It will increase.
B. It will decrease.
C. It will go to zero.
D. The cross-sectional area does not affect the resistance.

The car hoist allows the car to be driven onto the platform, after which the rear wheels are raised. if the loading from both rear wheels is 1380 lb, determine the force in the hydraulic cylinder ab. neglect the weight of the platform itself. member bcd is a right-angle bell crank pinned to the ramp at c. the force is positive if in tension, negative if in compression.

Determine the maximum r-value of the polar equation r =3+3 cos 0

The protons in a nucleus are approximately 2 ✕ 10^−15 m apart. consider the case where the protons are a distance d = 1.93 ✕ 10^−15 m apart. calculate the magnitude of the electric force (in n) between two protons at this distance.
