lestion: 1 ianna is pushing a lawn mower using a force of 300 N.If she hes the mower a distance of 800 m.how much work has she done? A. 1,100J B. 24,000J C. 110 .000 J D. 240,0 ooJ Question. 2 Which simple machine includes an inclined plane? A. wheel and axle B. lever C. pulley D. screw

## Step1<br />For question 1, we need to calculate the work done by Ianna. The formula for work is given by:<br />### **Work = Force x Distance**<br />In this case, the force applied is 300 N and the distance moved is 800 m. Substituting these values into the formula, we get:<br />### **Work = 300 N x 800 m = 240,000 J**<br /><br />## Step2<br />For question 2, we need to identify which simple machine includes an inclined plane. The options provided are wheel and axle, lever, pulley, and screw. Among these, the screw is the simple machine that includes an inclined plane.
