if you have have the equation v(t)=30sin(63t- pi/2) where max voltage is 30 and the period is 100ms. at t=0 v is 30 (sorry i could give you a graph) how would a DC shift of 10 volts change the graph
Can anyone help me out. I don't know of any equation that i can us eto solve this A force 1000N is required to raise a concrete block to the surface of a fresh wate rlake. what is the force required to lift it out of the lake. I know that i need to figure out what the weight outside of wate ris...
i am working on this problem and can't figure out how to go about it at what depth in fresh water is the density 1% greater than its value at the surface? i am not sure what equation to use.My answer choices are 230m, 2300m, 23,000m, or 230,000
