Answer: Option (C) is the correct answer.
Explanation:
In a chemical reaction, where two different compounds or a mate and a compound are reacting with each other then more reactive metal is able to displace less reactive metal.
When only one element gets displaced then it is known as a replacement or single replacement reaction.
For example,
Here, aluminium is more reactive in nature as compared to iron. Hence, iron is replaced by aluminium and this reaction is known as replacement reaction.
Thus, we can conclude that the given chemical reaction is replacement.
Answer:
The electric potential will be "259.695 volt".
Explanation:
In the given question, the figure is not provided. Below is the attached figure given.
Given:
Now,
At point P, the electric potential will be:
⇒
By putting values, we get
⇒
⇒
Answer:
Explanation:
The coordinate sketch for the system is shown in the attached file below. Also, in the cartesian coordinate system, since the height is less than the length and width, we did neglect the height. Thus, we eliminate the height and converted it to a two-dimension.
The given question is incomplete. The complete question is as follows.
A picture window has dimensions of 1.40 m, 2.50 m and is made of glass 6.00 mm thick. On a winter day, the outside temperature is , while the inside temperature is a comfortable
.
Part A
At what rate is heat being lost through the window by conduction?
Express your answer using three significant figures.
Part B
At what rate would heat be lost through the window if you covered it with a 0.750 mm-thick layer of paper (thermal conductivity 0.0500 W/m?K)?
Express your answer using three significant figures.
Explanation:
Formula for rate of heat transferred through single thick plane of glass is as follows.
=
=
When window is covered by paper then the rate of heat transfer is as follows.
=
=
Thus, we can conclude that heat lost is .
