Answer:
option 1 and option 2
Explanation:
option 1 and option 2
1)Take up the box: force is upwards, displacement is upwards as well, so good work as force & displacement are in the same direction
2) Accelerating:: because the individual is moving, force is positive, displacement is also in the same direction, so the work is positive.
3) carrying box at fixed speed :: as speed remain constant , force = 0 , therefore work =0
4) Decelerating to stop :: force is -ve because it is moving to finally stop, thus negative work
5) Lowering of the box :: force acts up direction , displacement is down , hence -ve work
Answer:
Barton's Taco Tico
1. The wages paid to the taco makers and other employees are variable costs.
2. The cost of materials are also variable costs.
Explanation:
Variable costs vary in total but remain fixed per unit. For example, the wages paid to the workers have a fixed rate. Therefore, the total will vary, depending on the total hours worked by each worker. Similarly, the costs of materials vary in total, but the price per material may be relatively fixed.
Debbie has a low tolerance for ambiguity.People who are high in execution have a tendency to have a low tolerance for ambiguity. They're the sort of individual who you give an errand, and they return to you with an entire rundown of inquiries, since they need to have the capacity to deliver a result that addresses your issues. Though with individuals who have a high resistance for uncertainty, they hazard doing things the wrong way a great deal of the time and conceivably committing a ton of errors.
