The outer layer of space ships are covered with tiles primarily to protect the shuttle for entering back into the atmosphere. On re-entry space ships generally take a great deal of heat damage, as well as being worn down by the atmosphere.
There are 92 natural ones and about 20 more made in particle-Physics labs.
If we only stick to the 92 natural ones, then there are
(92!) / (88! times 4!) = 2,794,155 possible answers to your question.
Here's one: Osmium
Neodymium
Iridium
Gold .
Answer:
Part A W= 2772J
Part B = -2.772J
Explanation:
Work = force × distance
Part A when you move from lower to upper level
= mgh
= 63× 4.4×10
=2772J
=2.772KJ
Part B
When you move from upper to lower
The acceleration due to gravity becomes negative -10m/s^2
Therefore Work =-2772KJ
Work = -2.772KJ
Answer and Explanation :
The opposition of the flow of alternating current produced by a magnetic field is called inductive reactance it is denoted by 
, The value of the inductive reactance depends on the value of inductance. The good thing about inductive reactance is that it is not responsible for the power loss as resistance is responsible for the power loss
Answer:
T = 0.638 s
Explanation:
vmax = Aω
ω = 7.02/0.713 = 9.8457 rad/s
T = 2π/ω = 2π/9.8457 = 0.63816
