For Ethernet, if an adapter determines that a frame it has just received is addressed to a different adapter
a. it discards the frame without sending an error message to the network layer
b. it sends a NACK (not acknowledged frame) to the sending host
c. it delivers the frame to the network layer, and lets the network layer decide what to do
d. it discards the frame and sends an error message to the network layer
Answer:
Option A
Explanation:
The nodal address has to match the signal message address for it to function well but if the it doesn't match the nodal receiver address, it disregards it.
The correct answer is
b. low frequencies and low energy.
In fact, microwaves and radio waves have frequency up to
, which are really low compared, for instance, to the frequency of gamma rays (
). Moreover, the energy of an electromagnetic wave is directly proportional to its frequency:

where h is the Planck constant and f the frequency; therefore, low frequency means also low energy.
Answer:
12 m/s

At what maximum speed is the cyclist traveling for a short time if he has a maximum power of 420W and at this speed he must overcome the resistance 35N.
The Power, P, expended by a moving body with velocity, v, moving against a resistive force of F is given as
P = Fv
P = 420 W
F = 35 N
v = ?
420 = 35v
v = (420/35) = 12 m/s
In Polish/Po polsku
Moc P, wydana przez poruszające się ciało z prędkością v, poruszająca się przeciw sile oporu F, jest podana jako
P = Fv
P = 420 W
F = 35 N
v = ?
420 = 35v
v = (420/35) = 12 m/s

Answer: damping coefficient = 1.5×10^5Ns/m
Explanation:
Please find the attached file for the solution
The statement above is TRUE.
When analyzing forces it is permitted to break the motion and forces into horizontal and vertical components. This is especially true for two dimensional projectile motion, in order to simplify the calculation, the forces and the motion has to be broken down into horizontal and vertical components. The vertical component is affected by the force of gravity while the horizontal component is not affected by gravity for short displacements. With greater displacement, the force of gravity comes into play.
