What must be true about two objects if heat is flowing between them

Vedmedyk [2.9K]

Answer:

The objects must be different temperatures.

Explanation:The objects must be different temperatures. eat will flow from Object 1 to Object 2 in examples 1, 2, and 4, and heat will flow from Object 2 to Object 1 in Example 3. Which factors affect heat transfer between a warm and a cool substance?

The first hill of a roller coaster is 42 meters high. The top of the second hill of the one

Marta_Voda [28]

Answer:

Part a)

Speed of the roller coaster is

$v = 13.3 m/s$

Part b)

Since it is moving with non zero speed at some height above the ground

So we will have

Kinetic energy + Potential energy Both

Explanation:

As we know that there is no friction on the path

So here we can use mechanical energy conservation law

so we will have

Part a)

$U_i + K_i = U_f + K_f$

$mgh + 0 = \frac{1}{2}mv^2 + mgH$

$34500(9.81)(42) = \frac{1}{2}(34500)v^2 + 34500(9.81)(33)$

$v = 13.3 m/s$

Part b)

Since it is moving with non zero speed at some height above the ground

So we will have

Kinetic energy + Potential energy Both

According to the de Broglie relation, the wavelength of a "matter" wave is inversely proportional to the momentum of the particl

ValentinkaMS [17]

Answer:

Yes the statement is correct

Explanation:

The de-broglie relation is mathematically represented as

$\lambda =\frac{h}{p}$

where

p is momentum of the system

From the relation we can see that the wavelength is inversely proportional to the momentum of the particle.
