Which of the following demonstrates a translation?

Physics
2 answers:

A translation means moving something up down or left/right

Lets use that definition to figure the answer out

A). A spinning Wheel

No, because it is spinning, not moving up or down left/right

B). a child swinging on a swing

No because the child is in a swinging state of motion, not left or right, or up or down.

C). The blade of a kitchen blender

No, because it is in a spinning motion, which we ruled out to be incorrect previously.

Therefore the correct choice is

<h2>D) A sliding hockey puck</h2>

Why?

A sliding puck is always moving left or right, view the hockey field as an XY plane, and it is being translated left & right.

2) Why do you think fossil fueled cars are still out numbering alternative and replacement fueled cars even though fossil fuels
Misha Larkins [42]

Answer:

Fossil-fueled cars are still outnumbering the alternative and replacement-fueled cars because they are generally cost-effective and are efficient.

Explanation:

<em>Fossil fuels</em> are non-renewable energy that cannot be replenished. Although many people know how harmful using them can be to the environment, still, people continue to buy cars that are powered by it. This is because, <em>using fossil-fueled cars can help you save money</em> compared to using<em> replacement-fueled cars.</em><em> Its engines are also more powerful,</em> which means they can arrive at their destination in just a few minutes. <u>This makes it efficient.</u> The cost of maintaining a fossil-fueled car is less expensive compared to<em> replacement-fueled cars.</em> People are naturally keen when it comes to budgeting, thus, many people still buy cars powered by fossil fuels.

A physicist does 100 joules of work on a simple machine that raise a box of bioks through a heigjt of 0.2metres. if the efficien
11Alexandr11 [23.1K]

Answer:

the work converted to thermal energy is 40 J.

Explanation:

Given;

work done by the physicist,w = 100 J

height through which the book is raised, h = 0.2 m

efficiency of machine = 60% = 0.6

The useful work done by the machine is calculated as;

useful work = 0.6 x 100 = 60 J

The wasted energy = 100 J - 60 J

The wasted energy = 40 J

The wasted energy by the machine is possibly converted to thermal energy by the frictional part of the machine.

Therefore, the work converted to thermal energy is 40 J.
