Determine the linear velocity of a point rotating at 25 revolutions per minute at a distance of 2 feet from the center of the rotating object. Give answer in feet/sec/ 25/60 = 5/12 revs per second Convert rev per second to rad/sec 5/12*2*pi = 2.618 rad/sec at a distance of 2 ...

Given that x is an integer between -2 and 2, state the relation represented by the equation y = 2-abs(x) by listing a set of ordered pairs. Then state whether the relation is a function. I think it's: (-2,0) (-1,1) (0,2) (1,1) (2,0)

**Physics - Waves**

So the answer is 400(345.8/340.8) = 405.87 Hz?

**Physics - Waves**

So the answer to the first question is 394.3 Hz and the answer to the second question is 400 Hz?

**Physics - Waves**

My thinking is: f2=f1(V/V+Vs) f2=Heard frequency=394.3 Hz f1=Source frequency=400Hz V=velocity of sound in medium=332+0.6(23)=345.8 m/s Vs=velocity of source=5 m/s I'm not sure about the second question, though.

When thrown into the air from the top of a 50 ft building, a ball’s height, S, at time t can be found by S(t) = -16t^2 + 32t + 50. When t = 1, s = -16(1)^2 + 32(1) + 50 = 66. This implies that after 1 second, the height of the ball is 66 feet. When t = 2, s = -16(2)^2 + ...
