If a car takes a banked curve at less than the ideal speed, friction is needed to keep it from sliding toward the inside of the curve (a real problem on icy mountain roads). (a) Calculate the ideal speed in (m/s) to take a 110 m radius curve banked at 15°. 16.99 Correct: Your answer is correct. m/s

ideal speed(v)≅17m/s

Explanation:

Given: Radius, r = 110 m

Angle(α) = 15°

g=9.81m/

Find; (a) The ideal speed, v.

tanα=

make V subject of the formula;

v=

v=

v=

v≅17m/s

cell differentiation  is how generic embryonic  cells  become specialized  cells. this occurs  through a process called gene expression. gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a  cell  functions.

explanation:

the higher the current the higher the mag field around it the higher the influence on the compass
