(WILL GIVE BRAINLIST) your class goes in a field trip to observe drilling machinery. the geologists at the drill site show you displays of drilled rocks to compare different types of drills and methods. the drilled holes in one dock display are significantly larger than the holes drilled in the display next to it. given this information, which statement is correct? A. the rock display with larger holes show petroleum drilling, which is deep underground. B. the rock display with smaller holes show petroleum drilling, which is closer to the surface. C. the rock display with smaller holes shows copper drilling which is deep underground.
D. he rock display with the larger holes shows copper drilling, which is closer to the surface.

Acube has a volume of 2011 cubic inches. what is the angle measure between a side of a cube and its interior diagonal?

11. you want to calculate the displacement of an object thrown over a bridge. using -10 m/s2 for acceleration due to gravity, what would be the total displacement of the object if it took 8 seconds before hitting the water?

The frequency of vibrations of a vibrating violin string is given by f = 1 2l t ρ where l is the length of the string, t is its tension, and ρ is its linear density.† (a) find the rate of change of the frequency with respect to the following. (i) the length (when t and ρ are constant) (ii) the tension (when l and ρ are constant) (iii) the linear density (when l and t are constant) (b) the pitch of a note (how high or low the note sounds) is determined by the frequency f. (the higher the frequency, the higher the pitch.) use the signs of the derivatives in part (a) to determine what happens to the pitch of a note for the following. (i) when the effective length of a string is decreased by placing a finger on the string so a shorter portion of the string vibrates df dl 0 and l is ⇒ f is ⇒ (ii) when the tension is increased by turning a tuning peg df dt 0 and t is ⇒ f is ⇒ (iii) when the linear density is increased by switching to another string df dρ 0 and ρ is ⇒ f is ⇒
