X-rays are high energy electrons
that can cause damage when exposed under extreme conditions. The best technology
that can block it is using a lightweight type of metal foam. It can take in
high energy collisions which also exhibits high forces. it does not only block
x-rays but also, neutron radiation and gamma rays.
Answer:
It would take 16.7 s for the work to be done by the engine.
Explanation:
From the question, given: Power = 390.3 kW
Work to be done = 6.5 x 
J
But, power and work done with respect to time, has a relationship of:
Power = 
So that,
time = 
Thus,
time = 
= 16.6539
time = 16.7 s
Time required is 16.7 seconds.
Thus, it would take 16.7 s for the work to be done by the engine.
Because the bell inside is halted and stops moving, so the changing of it going from side to side ISNT happening which is what causes the noise
In the first question, the answer would be the statement 'Brody is correct because the wave involves an input of energy'. The hand wave involves an input of energy and this energy is repeated and is carried from one place to another.
For the next question, the answer would be 'it is a transverse wave' because all are transverse waves.
