Dinosaur and bird so u can see how they developed and how they aged to become something popular<span />
1.085m
Explanation:
Using
a= lambda/sinစ
Sinစ= (587.5*10^-9) x 0.75*10^-3
= 0.000783
Sinစ=0.875*10^-3/d
0.000783= 0.875/d
d= 1.085m
It wears down its components causing it to not work as effectively, it also creates heat which can cause(according on the machine) it to burn out. Another Immediate problem is that it can slow the machine causing it to lose efficiency.
Answer:
by reducing friction.....
Answer:
The probability of higher energy state is 0.4200.
Explanation:
Given that,
Temperature = 247 K
Energy difference between two states 
We need to calculate the probability of higher energy state
Probability of 
Probability of 
The total probability is

Here, E₁ = lower energy state
E₂ = higher energy state
Put the value of E₁ in to the formula



Here, 
Put the value into the formula


Hence, The probability of higher energy state is 0.4200.
