Answer:
153.0815W/m.K
Explanation:
Heat transferred in phase is changed is expressed as:
(m-mass, Q-heat, L-Latent heat of phase change)
Latent heat is the heat required to change the phase of 1kg of the material.
#The rate of heat flow(by conduction) per unit time:
#Heat flowing through melting ice.
To solve for k:
The thermal conductivity k of the metal is 153.0815W/m.K
Answer:
Explanation:
The electric field applies a force qE, but only in the y direction. This means that the x component of the
momentum must be conserved:
0 = Fx =dpx/dt
=⇒ px is conserved
pxi = γimvxi = pxf = γfmvxf (see the attactments)
the particle will acquire a velocity in the y
direction, and vxf <vxi. The x-component of the velocity, and thus the x-component of the momentum
must decrease.

Answer:
D physiological condition
Explanation:
Sensation and perceptions are complimentary to each other but have different roles within the brain. Sensations are the process of experiencing the world with the five senses and sending that information to the brain. Perceptions are the way we interpret sensations.
<span>So we want to know what does orange light has when we compare it to yellow light. So when we take a look at the electromagnetic spectrum we can see that orange color has longer wavelength than yellow color. So the correct answer is A. alonger wavelength.</span>
