<span> If you make 46 pushes then your sister swings through 46 cycles and she does so in 90 seconds. The frequency would be 46/90 = 0.511 Hz.</span>
80% from burning fossil fuels
<span>So we want to know which statement is true for the body of mass m=2000kg that is lifted to a height of h=15m in t=15 s. Lets calculate each of the following: Gravity force on the body is F=m*g=2000*9.81=19620 N so a is FALSE. Potential energy of the body when it is lifted to the height of 15 m is Ep=m*g*h=2000*9.81*15=294300 J so b is FALSE. Work to lift the body is: W=Fg*h=2000*9.81*15= Ep=294300 J so c is FALSE. Power P=W/t=294300/15=19620 W So d is TRUE. </span>
Answer:
Elbow Lake
Explanation:
An oxbow lake is a stagnant lake that forms along a winding river due to soil erosion resulting in an abandoned stream, cut off from the river. An oxbow lake begins as meander or a curve in a river after some time, the curve becomes larger as a result of erosion and hydraulic action.
