The speed of sound in air can be expressed as 331 m/sec at 0 degree celsius. it increases 0.6 m/sec for each celsius degree above zero. assume the temperature of the room is 25 degree celsius. calculate the speed of sound in m/s at this temperature.

Let f(x) = x4- 8x2 . find the relativeextrema of this function using the second derivative test.

A3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular? a 3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular?
