### Power Exertion Order Activity**Objective:**Arrange the individuals by the amount of power exerted from least to most.**Instructions:**Use the arrows to move each item into the correct order. Click the "up" arrow to move the item up, or click the "down" arrow to move the item down. Once all items are in the correct order, submit your response.**Task:**Identify the order from least power exerted to most power exerted based on the given data.1. **Jennifer**: - Lifts 490 N - Distance: 1 m - Time: 2 seconds2. **Paul**: - Lifts 1,470 N - Distance: 1 m - Time: 2 seconds3. **Mark**: - Lifts 980 N - Distance: 1 m - Time: 1 second**Analysis:**To determine the power exerted, use the power formula:\[ \text{Power} (P) = \frac{\text{Work} (W)}{\text{Time} (t)} \]Where \( \text{Work} (W) = \text{Force} (F) \times \text{Distance} (d) \).Calculate the power for each individual:- **Jennifer**: \[ P = \frac{490 \, \text{N} \times 1 \, \text{m}}{2 \, \text{s}} = \frac{490}{2} = 245 \, \text{W} \]- **Paul**: \[ P = \frac{1,470 \, \text{N} \times 1 \, \text{m}}{2 \, \text{s}} = \frac{1,470}{2} = 735 \, \text{W} \]- **Mark**: \[ P = \frac{980 \, \text{N} \times 1 \, \text{m}}{1 \, \text{s}} = \frac{980}{1} = 980 \, \text{W} \]**Order from Least to Most Power:**1. Jennifer (245 W)2. Paul (735 W)3. Mark (980 W)Please move the items accordingly

pomtj Retake question Students roll a tennis ball down two different ramps of equal height but different angles as shown in the diagram below. Ignore friction. The students notice that the tennis ball rolls down the steeper ramp in less time than the longer ramp. Which tennis ball has more kinetic energy at the bottom of the ramp? (5c1; DOK 1). The tennis ball on the less steep ramp has more KE because it can accelerate for a greater time. Locked The tennis ball on the steeper ramp has more KE because it exerts a greater force on the tennis ball. The tennis ball on the less steep ramp because the ramp is much longer, so it would do more work. They would have the same KE since the change in PE is the same for both tennis balls.
