Answer:
I think it is eyeglasses
Explanation:
I think this because the glasses usually reflect the same thing sometimes and the light passes through really easy

BIg, big questions in Thermodynamics. ...
Not without "help" it can't. There are two versions of this. One is that it is impossible to take heat from something and convert it completely into work - there has to be some waste at a lower temperature. The other is that heat will not "spontaneously" go from a colder place to a warmer place. So, a domestic fridge needs a device to transfer the heat, that's that buzzing sound of a motor driving a refrigerant round in a cycle, taking heat out the fridge and making the surrounding warmer. It's also called a heat pump. The area near where the pump puts its heat can be felt to be warm.
Answer:
0.5 m.
Explanation:
From the question given above, the following data were obtained:
Force (F) = 5 N
Work done (W) = 2.5 J
Distance (s) =?
Workdone is simply defined as the product of force (F) and distance (s) moved in the direction of the force. Mathematically, it is expressed as:
Work done (W) = Force (F) × Distance (s)
W = F × s
With the above formula, we can obtain the distance to which the book has moved as follow:
Force (F) = 5 N
Work done (W) = 2.5 J
Distance (s) =?
W = F × s
2.5 = 5 × s
Divide both side by 5
s = 2.5/5
s = 0.5 m
Therefore, the book moved 0.5 m when the force was applied.
Math is the process of using the given information, along with
all the general stuff that you know, to find the missing information.
With no given information, we have no way to even guess at
an answer.
