Answer:
A) Become 1/ 2 of its original value.
B) Become one-half of its original value.
Explanation:
As we know that heat transfer trough the wall of thickness t given as
Where
K=Thermal conductivity of the wall
A= Cross sectional area of the wall
t=Thickness of the wall
ΔT=temperature difference across the wall surfaces.
When the thickness become double ,lets sat t' = 2 t
Then new heat transfer
Therefore the new heat transfer become half of the original.
Answer:
and the forces acting on the particle as a function of time.
Explanation:
The principle of linear impulse and momentum is obtained by integrating the equation of motion with respect to time. hope this helps you :)
Answer:
The magnitude of the maximum radial acceleration of the stone is 122.034 m/s^2
Explanation:
Maximum radial acceleration (a) = w^2r
w = v/r
w^2 = (v/r)^2 = v^2/r^2
a = v^2/r^2 × r = v^2/r
v is the maximum speed the stone attains = 12 m/s
r is the radius of the circular path = 1.18 m
a = 12^2/1.18 = 144/1.18 = 122.034 m/s^2
Answer:
Explanation:
Maybe start by trying to draw out some transverse waves, longitudinal waves, stationary waves etc. From there you could explain things about each type. For example, particles oscillate in the direction of energy transfer in longitudinal waves or you could include that all electromagnetic waves are examples of transverse waves. Hope this helps you get started :)
