Answer:

<em>UP</em>

Explanation:

heat flows from higher level to lower level

( higher concentration to lower concentration )

and since temperature in above block is less than the lower block, the heat will flow from lower block to higher block .

Chứng minh V=kq/r từ mối liên hệ giữ E và V
Marat540 [252]

Answer:V=Aq=KQr

Explanation:

Không biết V bạn kí hiệu ở đây là gì nhỉ? Có phải là điện thế?

Điện thế tại 1 điểm trong điện trường được định nghĩa là công làm vật dịch chuyển từ vị trí đó đến vô cùng. V = A/q

Chứng minh thì được, nhưng chỉ e bạn không có hiểu biết về nguyên hàm, tích phân nên không hiểu.

- Xét tại vị trí cách điện tích Q một đoạn x, khi đó điện tích q sẽ chịu 1 lực: dF=KQ.qx2

Điện tích q dịch chuyển 1 khoảng dx rất nhỏ. Khi đó công do lực điện trường gây ra là:

dA=dF.dx=KQ.qx2dx

Công để dịch chuyển điện tích q từ vị trí r đến vô cùng là:

A=∫∞rdA=∫∞rKQ.qx2dx=KQ.qr−KQ.q∞=KQ.qr

Theo đúng định nghĩa: V=Aq=KQr

In an electron microscope, electrons are accelerated to great velocities. Calculate the wavelength of an electron traveling with
Diano4ka-milaya [45]

Answer:

Wavelength, \lambda=1.04\times 10^{-13}\ m

Explanation:

It is given that,

Velocity of an electron, v=7\times 10^6\ m/s

Mass of an electron, m=9.1\times 10^{-28}\ kg

We need to find the wavelength of an electron. It can be calculated using the De- Broglie wavelength as :

\lambda=\dfrac{h}{mv}

\lambda=\dfrac{6.63\times 10^{-34}}{9.1\times 10^{-28}\times 7\times 10^6}

\lambda=1.04\times 10^{-13}\ m

So, the wavelength of an electron is 1.04\times 10^{-13}\ m. Hence, this is the required solution.
