Answer:
P = 5280 W
Explanation:
The conductivity of the materials determines that heat flows from the hot part to the cold part, the equation for thermal conductivity transfer is
P = Q / t = k A (
-
) / L
Where k is the thermal conductivity of the glass 0.8 W / ºC, A the area of the window, T the temperature and L is glass thickness
Let's calculate the window area
A = l * a
A = 2.0 1.0
A = 2.0 m²
Let's replace
L = 0.5 cm (1 m / 100 cm) = 0.005 m
P = 0.8 2 (20.5 - 4) / 0.005
P = 5280 W
The momentum should be .5 because you multiply the mass and velocity to get momentum
Answer:
Definiton 1.the refusal to accept or comply with something; the attempt to prevent something by action or argument
Definition 2. the ability not to be affected by something, especially adversely
Definition 3. the impeding, slowing, or stopping effect exerted by one material thing on another
Definiton 4: the degree to which a substance or device opposes the passage of an electric current, causing energy dissipation. Ohm's law resistance (measured in ohms) is equal to the voltage divided by the current.
