Answer:
the horizontal force acting on rod is - 25.909 N
veritical force is 25.48 N
Explanation:
Given data:
mass of rod is m 2.6 kg
length of rod is 1.5 m
Hinge distance from the wire is 0.70 m
Apply torque law about hinge
Tension in the wire is
= -25.909 N
the horizontal force acting on rod is
Fx = T
FX = - 25.909 N
vertical force is
Fy = mg
Answer:
a) L= 3568 m
b) 9×10^{-5} sec
c) 8.92×10^{-5} sec
Explanation:
runway length on the Earth L_o = 3600 m
Speed of the spacecraft flying past v= 4.00×10^7 m/s
then Einstein's length contraction theory,
Solving we get L= 3568 m
b) Time interval for an observer on earth when the spacecraft is directly over one end of the runway until it is directly over the other end.
L_o= 3600 m
speed v= 4.00×10^7 m/s
Then time interval Δt = L_o/v= = 9×10^{-5} sec
c) for the pilot the time interval will be
Δt_o = L/v = = 8.92×10^{-5} sec
Hi!
So, nuclear power plants are interesting. Many people may automatically assume that they will 'pollute' our atmosphere, but they do <em>not </em>produce pollution!
There is one <em>very </em>serious issue with nuclear power plants, however. If not handled properly, we can spill serious radioactive material. This material can be <em>deadly. </em>
Another issue is that it is not a renewable source. It won't last forever, so we will eventually have to find another alternative.
On the flip side, nuclear energy is <em>extremely </em>efficient and powerful. It is also a fairly clean way to gather energy, which makes it an attractive option knowing the state of our environment.
Hopefully, this helps! =)
